Battery Care and Troubleshooting

Some tips for taking care of your battery.

Image of a mechanic using a multi-meter to check the voltage of a car battery.Fall is upon us and it’s time to think about winter preparations. Among the many things on our lists, making sure our cars are in tip-top shape to handle the tough Minnesota winter is a big item with many little things to be done. Among those little things is something not so little if it fails – the battery. Because the battery powers all the lights and accessories in your car, you need to make sure it’s ready for the long, hard job of powering through winter. Here is a quick breakdown of tips for you to make sure your battery is good condition as we roll into cold weather.

Signs your car battery is about to die.

Car batteries usually last two to five years, depending on quality, operating conditions, and condition of the vehicle.

There are a few simple warning signs that will tell you it’s time for a new battery.
Long crank times in any kind of weather.

If your car takes longer to start than usual, especially if the battery has not been replaced in more than three years, this is a sign that the battery is wearing out. If the engine has to crank excessively in order to start, the battery should be checked. Keep in mind that cold weather affects the battery and its ability to perform, so it’s fairly normal for your car to start with difficulty in the wintertime. Everything slows down in the cold, including electric current. It is also hard to vaporize gasoline, and oil thickens up when it’s cold. Batteries put out only half their normal power when the temperature is freezing – so be patient, but be aware. If your car “cold cranks” in warmer weather, it’s a good time to change the battery.

Engine cranks, but won’t start.

The engine cranks, but won’t turn over. This a pretty solid sign that the battery is dying or already dead. You could get a jump start, but you’ll just need another one when you turn off the car. Driving around town, going from jump to jump might be a unique way to meet people, but let’s face it – it’s no way to spend a weekend. Get a jump and get a new battery.

image of jumper cables attached to car battery terminals.Too many jump starts will kill a battery.

Jump starting a battery too much will kill it. It’s hard on a battery when you basically shock back into action. If you have to jump start your car more than three times in a week, it’s time to replace the battery. One thing you can try that will get you through the interim is get the jump, then let the engine run for 30 minutes so the alternator can recharge the battery. Once this is done, shut off the car, wait two or three minutes, then try to start the car again. If it starts, turn it off, wait another couple minutes, then start it again. If it consistently starts, you probably won’t be stranded wherever you go next – but that doesn’t mean your battery is good to go. Your next stop really should be to get a new battery.

Engine won’t crank, won’t start, and there are no lights.

This is a pretty sure sign the battery is dead. Again, you could get a jump, but the battery has left the building – or the engine compartment, as it were. Something to consider in this situation is there might be a combined issue with the alternator, because that’s the part that keeps the battery charged. If the engine won’t crank, but you do have lights and other functions, then there could be other problems in the car’s electrical system or other areas of the engine. Some issues might be a bad ignition switch, a failed starter or solenoid (which usually causes a check engine light), or a poor electrical connection somewhere in the ignition system. Electrical problems should be properly diagnosed and fixed by a mechanic.

Your car starts fine one day, then does not start at all the next day.

There two battery-related issues that might cause your car to start intermittently or unreliably.

Battery terminals are loose, broken, or corroded.

A visual check usually will reveal if there is any corrosion or other problems with the battery terminals. You should check for tightness of cables, as well. If there is corrosion or the terminals are damaged, the battery will not perform at its best.

Parasitic draw on the battery is slowly draining its power.

Sometimes there is a condition somewhere in the electrical system called a “parasitic draw” that drains the battery of its power slowly, usually overnight. A certified mechanic can help diagnose, find, and fix this problem. If you decide to do it yourself, you’ll need a multimeter with amp capabilities up to 20 amps (A) and down to 200 milliamps (mA), and a fuse checker.

Simple battery maintenance will save you a lot of trouble.

  • Visual inspection to check for corrosion around the battery terminals. Look for a white powdery chalk-like substance. Corrosion affects electrical conduction. Clean the terminal with a wire brush. Never ever put baking soda on a battery to clean it. Coat it with grease before reconnecting the battery. The grease prevents further corrosion and improves electrical conduction.
  • Check the battery cables, as they are usually a prime cause of battery issues and are easy to check.
  • Make sure the cables are attached securely to the terminals and are not frayed, damaged, or falling apart. They should not wiggle or move around if they are properly tightened.
  • On older batteries with access to the cells, you can add distilled water to help the battery keep a charge.
  • Keeping a clean engine compartment in general prevents a lot of dirt and crud from covering the battery and collecting around the battery terminals, and possibly compromising its performance. It also makes overall engine maintenance and troubleshooting easier and less messy – and mechanic’s job a little easier if you have to bring your car in for a diagnosis.

SAFETY NOTES: Proceed with caution when performing maintenance on a battery. The sulfuric acid in batteries is highly corrosive and can burn your skin and eat holes in your clothes. There is even a slight danger of explosion. Always work in a well-ventilated area. Wear gloves and eye protection. Never lean over the battery when charging or testing it, or when jump-starting the engine. Keep a solution of water and baking soda handy in case battery acid gets on your clothes or skin. This mixture can neutralize the acid.

Reasons Your Car Won’t Start

There are many reasons your car won’t start.

There are few things worse than the feeling you get when you put your key in the ignition of your car, turn it, and… nothing. Silence. Probably more aggravating is when your car does make sounds like it’s going to start – it’s trying, it’s turning over, chugging, coughing. It just won’t catch and sputter to life.

Here are a few of the most common causes of your car not starting.

Starting with the starter…

A bad starter might lead you to think that the battery is weak or nearly dead. If the starter pulls more current than the battery has, it will turn slowly and make a “GRR, GRR, GRR” cranking noise, which sounds a lot like a weak or dying battery. If you hear a lot of grinding, that’s the starter, and it might be damaged – either the fly wheel or the teeth should be checked. If the starter doesn’t even respond, its relay or, solenoid might be burned out. The ignition switch could be the culprit, too.

image of jumper cables attached to car battery terminals.Of course, it’s the battery!

That is what many people immediately assume. It is indeed one of the most common causes of a car refusing to start, but a dead battery doesn’t mean a completely bad battery to be thrown away. It just means the battery doesn’t have a charge, and it might be that another component has failed. There are a lot of ways to knock out a battery.

  • Forgetting to turn off the headlights.
  • Door/courtesy light has been left on (door ajar, switch set to on).
  • Defective interior light generally unnoticed – trunk, glovebox.
  • Dirty, corroded battery terminals, or low battery water.
  • A defective, failing charging system that does not recharge the battery (see alternator).

Of course, batteries do get old and start to fail. Most have a life expectancy of about 3 to 5 years, depending on quality and your driving habits and conditions. Batteries have to work harder in cold temperatures, and usually show signs of failing when the weather turns cold.

Related: Transmission Problems Caused by Battery Corrosion

The alternator has failed and nothing is getting any electric love.

If the alternator has died, the battery has not been getting a return on its output and has not been charging. When the car is running, the charging system (alternator, voltage regulator) should recharge the battery and provide sufficient electrical power to the vehicle. The battery then serves merely as a backup. If the vehicle requires more electrical current than the charging system can provide, the battery picks up the slack. This can happen in extremely cold weather, particularly if you’re stuck in traffic and it’s snowing or raining. You’re constantly starting and stopping, brake lights are constantly on, headlights on, heater, defogger (which usually is accomplished through the air conditioning), interior dash lights, devices like smart phones being charged, radio on, possibly integrated wireless, phone, Bluetooth, onboard computer, entertainment, internet/satellite/cell service connections. It all takes electrical power. The alternator has a pretty tough, thankless job. The battery just sits there!

If the starter can crank the engine without a problem, then the battery and alternator are probably fine.

So, the engine cranks fine, but won’t turn over and go.

When you turn the key in the ignition and the engine cranks normally, but won’t catch or fire and start running, this means the battery and alternator are working as they should, and the problem lies elsewhere. If you keep cranking the engine, the battery will eventually run down and need to be recharged. So, what else could be wrong? Determining where or what might require a trip to a mechanic, but here are some things to be aware of.

Image - mechanic fixing fuel pumpThe fuel pump has conked out.

Here’s another component with a dirty, thankless job. The fuel pump sits in the gaseous darkness of the gas tank, pumping fuel the length of the car to the engine. A malfunctioning fuel pump can give different signs of imminent failure: faint whining, chugging or sputtering at high speeds, chugging or lack of power during acceleration, noticeable loss of power and performance, unexpected surging, and of course, an engine that won’t start.

Out of gas?

If the fuel pump is operating properly, then maybe you’re just out of gas. Check the needle on the dash. In some older cars you might have to turn on the ignition for the needle to register, but you shouldn’t have to start the entire engine. Of course, if the battery is dead, then checking the needle is not an option.

Cold weather and ethanol can cause problems.

Sometimes in cold weather, ethanol that is mixed in the gasoline can cause water vapor condensation in the fuel tank or fuel line. In cold weather, this water can freeze and cause blockages in the fuel line. Keep your gas tank at least half full during the winter to avoid this problem.

Your car might just need a tune-up.

It’s easy to forget about more simple, smaller parts and processes that happen in the engine. Spark plugs are a good example of things that often go overlooked. A thorough engine tune-up will address any basic operational issues, including spark plugs, timing, air/fuel mixture, and other things that can affect your car’s ability to start and run reliably.

Signs Your Suspension Needs Repair

Is It Time for a New Suspension or Just Repairs?

image - drawing diagram of automobile suspension suspension, all four wheels.It’s usually easy to tell if your car’s suspension is having issues, but it can be difficult to diagnose the actual cause of the problems. Bad or worn shocks, struts, springs, tie rods or ball joints can cause costly damage to your vehicle and make it unsafe to drive.

Unfortunately, the suspension is often taken for granted – but it supports the entire weight of your vehicle. Suspensions are more than just about a smooth ride. A worn out suspension affects your ability to control the car, especially when stopping or turning, and can affect performance at different speeds. Pay attention to how your car handles, sounds it makes, and have problems checked immediately as they come up.

We get it – wear and tear happens, it comes with every part of every car. Regular wear and tear also comes with the need for a regular inspection and maintenance plan. Suspension maintenance and repairs are just as important as any other maintenance items, like oil changes or brakes. If you ignore problems with your car and allow them to fester, you will end up with more and more repairs that cost more and more money to fix.

Symptoms of a Bad or Failing Suspension

There are many things to look for to determine if your suspension system is failing in some way or needs repair. Since the suspension affects so many other systems that influence the control you have over your vehicle, it’s important to be aware of symptoms to determine if individual parts or the system at large is failing.

Car Ride is Not Smooth

There are many reasons your car might not drive smoothly. Aside from the tires, the suspension is usually one of the first suspects when your ride becomes bumpy or rough. When you can feel every bump in the road and it makes your car bounce, it’s time to get your suspension looked at. You can test the suspension yourself by doing the “bounce test.” While the car is parked, put all your weight on the front end and then release. If the car bounces up and down like a kid at a techno concert, the shocks and struts need to be replaced.

Worn out shocks can mean big problems if you don’t get them replaced.

Shock absorbers keep your tires on the road. If they don’t, the car will bounce all over the road and become uncontrollable. Shock absorbers serve to “absorb” the bumps and bounces. When they wear out, you definitely feel it in the performance and controllability of your car. If they fail entirely, your car could be severely damaged.

Car is Difficult to Steer

If your car becomes hard to steer, especially at low speed, something might be wrong with the suspension. Because your steering is linked to the suspension and the two rely on each other to get their respective jobs done, it’s important to pay attention to the steering – it’s the way you control your car.

If something is affecting your control of the car, it could be the suspension or it could be something in the steering system itself.

image of woman driving, having trouble controlling car, passenger in panic, shouting stop.Low power steering fluid, worn or loose belts, worn out control arm bushings could all be part of the problem. Squealing or whining when you turn the wheels of your car is usually a sign that the power steering pump is failing. As you can see, when steering becomes difficult, it’s time to steer your car to a mechanic.

Car Drifts or Pulls to One Side

If your car drifts or pulls to one side as you drive down a straight road, it could be due to any one of a number of reasons – tires, brakes, steering or suspension. It’s a difficult problem to diagnose, but there are things you can do yourself to possibly eliminate the causes and save yourself a trip to the mechanic.

The first thing you can do is check your tires.

Check the tire pressure. An underinflated tire can cause the entire car to ride strangely, including pulling it to one side. If you find yourself constantly fighting your steering wheel, check the tire pressure. Additionally, you’ll experience uneven tire wear all around and decreased gas mileage. If the tires haven’t been rotated regularly, get them rotated. This can be a cost effective solution to an annoying issue.

Have the alignment checked.

If you do a lot of driving on rough roads, or have hit more than one pothole or curb, and you notice some weirdness in the steering, there’s a good chance you need an alignment. A poor alignment will cause uneven tire wear, which then becomes another potential cause of the car drifting or pulling.

If the suspension is damaged, get it fixed to avoid bigger issues.

If your car drifts or pulls, a tie rod, spring, or control arm could be broken. This will cause severe difficulty in steering and affect your ability to control the car beyond just casual drift or pull. Go to a mechanic and have it fixed immediately.

Car Sits Low or Nose Dives

If one corner of the car seems to sit low when it’s parked, this is a sign of a damaged or broken spring.

When driving, you’ll notice a clunking sound when you go over bumps or turn. This is because the damaged or broken spring can’t support the weight of the car. A blown spring will put undue stress on the shock absorber, too, and vice versa. The two work so closely together that if one goes, the other has to compensate. But the spring is primarily responsible for any variations you see in the level sitting of your car.

If your car nose dives, leans back or rolls, the shocks or struts need to be replaced.

Braking transfers the weight of the vehicle to the front, and if the shocks and/or struts are worn out, this will cause the car’s nose to dive or dip down much more than you’re used to. You’ll notice it. Additionally, the car will lean back when you accelerate, as the weight of the car is transferred to the rear. When you take a corner, the car will roll – not roll over, but lean excessively to one side. The car will not be level, but it will lean so one side of the car dips down and the other side rises up, all without the tires leaving the ground.

When to Get a Transmission Fluid Flush – Infographic

How often should you flush your transmission fluid?

Preventative maintenance can prevent costly repairs.

It’s a lot cheaper to do some regular maintenance to keep your car running smoothly. Part of your maintenance schedule should include a transmission fluid check and, if needed, a fluid flush. Here’s a handy infographic that tells you what to know.

Signs of Bad Fuel Injectors

Is It Time for New Fuel Injectors?

A fuel injector is part of your vehicle’s fuel system. Fuel injectors are the component that spray the fuel into the engine. These are controlled by the vehicle’s engine computer (ECM), which controls how it sprays fuel into the engine, following purposely timed intervals and patterns that help optimize the engine’s efficiency and overall performance.image of used, dirty, fuel injectors.

Symptoms of a Bad or Failing Fuel Injector

There are many things to look for to determine if your fuel injector is failing in some way or needs to be replaced. Since these are a part of the fuel system, it’s important to watch for these symptoms to determine if the fuel injector is bad or failing.

Engine Performance Issues

Often, when a fuel injector is clogged or starting to fail, you will experience engine performance issues. These types of issues can include everything from engine performance issues to strange smells – all of which your local Minnesota AAMCO auto repair center can diagnose.

Check Engine Light Comes On

A bad fuel injector can cause too much or not enough fuel to be delivered into the engine – this will cause the Check Engine light on the car to turn on, indicating an issue. Your trusted Minnesota AAMCO auto repair center can help decipher your check engine light and figure out what issues need to be addressed.

Vehicle Won’t Start or Struggles When Starting

If the fuel injector is not delivering enough fuel to the engine system, this can cause the car to struggle when trying to turn over or not turn over at all (just cranks with no result). This can also cause the engine to stall due to the air-fuel ratio not being correct.

Vehicle Misfires

This can occur if your engine is not receiving enough fuel from the fuel injector – which stems from fuel injectors being clogged and dirty.

Poor Idle

You will notice a rough or choppy engine idle when the car is not moving. It might even feel like the engine it going to stall every time you stop. This can be caused by the fuel not being properly injected to the engine cylinder.

Engine doesn’t Reach Its Full RPM

If too much fuel is being injected into the engine, this can cause the engine to surge. This will make it feel like your car is jumping forward quickly but struggling to fully take off. You may also notice a loss in power or acceleration. 

Smell of Fuel

Another symptom of a failing or leaking fuel injector is a fuel odor. Because fuel injectors hold high amounts of pressure, and over time they can begin to leak around the seal at the tip of the injector or nozzle. A leak from either of these areas can affect engine performance – most noticeably fuel efficiency – and will give off the smell of gasoline. If you begin to smell gas fumes, you should take your car into a mechanic as soon as possible to avoid any further damage or safety hazards.

image of new, clean fuel injectors ready to be installed.Because fuel injectors are one of the main components for an engine being able to run – by providing fuel to the engine – they are extremely important to the overall functionality and performance of your vehicle. If you start noticing any of the previously mentioned symptoms, or suspect that there could be some issues with your fuel injectors or any part of the fuel system, schedule an appointment with a professional mechanic to diagnose the problem and provide next steps for how to fix it.

How to Tell if Your Brakes Are Bad

Identifying Common Brake Problems

Squeaking, Squealing, Grinding, Shaking

Your brakes need to be fixed.

Over your vehicle’s lifespan, you will likely experience a number or different issues specifically related to the brakes. While these repairs may not always seem to be pressing, problems with the brakes can become dangerous very quickly. Don’t worry! We are going to review some of the most commonly reported problems which require repair.

Paying attention to changes in the way your vehicle drives can indicate brake problems with minimal mechanic experience. We are going to outline some of the most common sounds, smells, and sensations which signal trouble. We will also look at some of the most frequently replaced brake system components.

Brake Pads

It is quite common to replace brake pads, and this is one of the simpler solutions to brake problems. Typically, brake pads are replaced approximately every 50,000 miles (though this really depends on your vehicle make, type, and the type of pads you are using – check your manual for recommendations). Worn pads will cause a metal on metal, grinding sound, and you will notice the braking distance increases. When a brake pad overheats, it causes it to crack, and then they will begin to squeak or squeal. If you’re hearing this sound on a regular basis, it is absolutely time to get them replaced!

Rotors

The surface of rotors must be flat in order to keep contact with the brake pads. Over time, a rotor’s surface will begin to warp due to heat damage, which then causes the vehicle to pulsate or jerk when the brakes are applied. If your rotors are overheated the surface will have a blue or purple hue which hardens the surface preventing the pads from gripping the rotors. Some rotors can be resurfaced (where they physically reshape these discs so that they are smooth and flat again), while others require replacing.

The caliper and caliper brackets hold the brake pads and force them against the rotor to stop the vehicle. When caliper pistons become stuck, the car will begin pulling to one side as the brakes are applied. This will also cause your rotors to overheat and wear down much more quickly. Essentially, one of your brakes is engaged regardless of whether you are driving or stopped. This is much more than just an inconvenience, this can be quite dangerous and should be addressed immediately.

Emergency Brake Engagement

It may seem like more of an issue of attention to detail, but this happens more often than you may think! It is easy to forget when you’ve put your emergency brake on, especially since some modern cars use a button instead of a lever. Leaving your emergency brake on will cause performance issues and damage to the entire system. If you suddenly hear a squeaking or grinding sound, be sure to confirm that your emergency brake is not engaged. 

Brake Light

When the brake light on the dashboard is illuminated, it can indicate that there is a serious issue with the braking system. In many cases, this light points to a problem with the hydraulics and should be inspected and repaired right away. This is not an error light which you should ignore. (This light also indicates that your parking brake is engaged!)

Smoking Brakes

Your brakes should not smoke… Ever. If you are experiencing this, it means that the brake pads have been burned, or that something is leaking onto the brakes. This is a dangerous problem which should be addressed immediately. Any indication of burning should be handled with urgency to prevent further damage and major repairs.

Leaks

If the brake system is leaking, it is usually a sign of a hydraulic issue. If you are able to press the brake pedal all the way to the floor, it can often be traced back to a leak. This type of leak is typically a slow leak where the brake fluid is lost gradually, but this eventually causes the brake system to fail altogether. A puddle of fluid on the ground or a low brake pedal are all symptoms of a leak.

AAMCO Minnesota for All Your Brake Services

Your brake system has a big, important job to do, and should not be taken for granted. Always be aware of the last time work was done on your car’s brakes, and make sure you keep them in top stopping condition! Your vehicle’s manual should provide you a recommended maintenance plan. At AAMCO Minnesota, we have seen it all, and we’ll help you make the best decision regarding solutions to the problems you’ve been encountering. Give us a call, or book an appointment online to get your car back in tiptop shape!
