Automotive Tips from Ken's Auto Center: Battery Testing

The simple fact is that 70% of car batteries fail within 4 years. They just need to be replaced at Ken's Auto Center when they are no longer able to hold a full charge.

Batteries are a big ticket item for most San Diego drivers and it’s tempting to put off buying a new one as long as possible. But a battery that cannot hold a full charge requires the alternator to work extra hard, causing it to wear out prematurely.

Your Ken's Auto Center service advisor can test your battery to see if it should be replaced. Testing is a good idea for CA drivers because a battery might still be good, but become dead because of a bad alternator or even a worn serpentine belt and tensioner.

Battery Replacement for Your vehicle

Modern vehicles in and around San Diego run on 12 volt electrical systems. 12 volts is enough to get the job done for San Diego drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us CA drivers have all the power outlets for our cell phones, computers and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given San Diego drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your vehicle. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more important to get it replaced.

Special safety precautions are taken when working with batteries at Ken's Auto Center in San Diego, CA. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any San Diego resident working with their battery. Be careful to not spill acid on your clothes or the vehicle's paint. Of course, avoid short circuiting the battery as well.

Sometimes there is quite a price range in San Diego auto part stores for batteries that will work in a particular car. Think of it as "good," "better" and "best." More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves in the long run for San Diego drivers.

The Need for Speed (Wheel Speed Sensor Maintenance)

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue.

Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. 

If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll still have working brakes, but you will lose the functionality of that computerized system.

When your vehicle warns you the ABS has a non-working sensor, you can have a technician check to see what's going on. It could be one of the sensors is dirty and a cleaning will solve the problem.  But it also could be that one or more sensors needs to be replaced. 

A technician will use computerized diagnostic equipment to determine what and where the problem is, replace any bad parts and then check to make sure the system is fully operational. 

Antilock brakes and traction control are significant technologies that help prevent your vehicle from slipping on less-than-perfect road surfaces, especially useful during wintery weather.  Make sure they're helping you drive the way they designed to.

Wired! (Battery Cable Service)

Colder weather brings out the worst in a vehicle's battery.  On a very cold day, you may have experienced that your engine cranks slowly when starting.  But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables.  After all, you have to have some way to get the current out of the battery and out to where it needs to go.

Battery cables have a couple of enemies: corrosion and age.  You may have looked under the hood and noticed a light-colored powder or crust around the terminals.  That's what happens when acids corrode the ends of the battery terminals.  Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all.

Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle's electrical parts (like the sound system or the horn) don't work or, in some cases, the vehicle won't start at all.

When you take your vehicle to a repair facility, the technician will use instruments to check voltages to see how much current is getting to what location. That includes a starter draw test during which the battery's voltage is checked when the starter is cranked.  The technician will also visually inspect the cables and the charging system. To make sure the alternator is putting out the right voltage, the technician will measure that as well. 

If the problem is found to be the battery cable assembly, the entire set may have to be replaced. Sometimes they can be repaired. 

During the colder months, it's vital that your vehicle has the proper power going to its electrical components.  Having a vehicle that won't start or run smoothly is not something you want to battle with when you're already up against challenging weather.  Keep your electrons flowing… and your vehicle moving.

Keeping Your Cool (Water Pump Replacement)

No matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected.  Well, cool, anyway. If your vehicle has a gasoline engine, it's powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT.

There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump.  Technically, it's pumping more than water. It should actually be called the "coolant" pump since the liquid that circulates through the system is a mixture of water and coolant. 

Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that shows the temperature is too high, it could mean a bad water pump. 

They can fail for many reasons. They have bearings in them that wear out, as does the seal between the pump and the engine. They're often driven by a belt or chain that can go bad.  Corrosion can spell the end of a water pump, too. 

If a technician determines your water pump has failed, it's time to replace it. In addition, other components of the cooling system will be inspected.  The best way to avoid a water pump failure is regular maintenance of your cooling system which includes regular draining and flushing of the coolant. 

Just like it's important for you to keep your cool, the same goes for your vehicle's engine.
