Knowledge is Power (Battery Testing)

It’s likely happened to you once or twice.  You head to your vehicle, open the door, turn the key and… lo and behold, your battery is dead. Now you’re stranded, may have to get a jump or a tow, and you’ll definitely be late for wherever you were headed. While your vehicle may sometimes give you warning signs, other times it doesn’t.  

As many as one out of every four vehicles will have to have its battery replaced in the next 12 months.  If you don’t want to be surprised the next time your battery fails, consider having it tested.

There are different types of battery testing.  One measures voltage. Another checks for something called conductance.  By sending a certain type of electric current into the battery, it can measure how healthy your vehicle’s battery is.  There’s also a load test.  It checks how your battery is working while drawing power from it.  Newer test equipment found in professional service facilities can check for a number of different conditions using different methods. 

Most vehicle batteries last around five years.  It all depends on how you drive and in what conditions.  Extreme heat and cold will take their toll on a battery and shorten its life.  Stop-and-go city driving will also place batteries under more stress than smooth, continuous driving.  

So, what are some signs that your battery is starting to show its age? Well, the battery or alternator light may illuminate after you’ve started the vehicle or come on while you are driving.  If you’ve left lights or some equipment on and drained the battery, that can be very hard on it.

Because the battery is one of your vehicle’s most important components, it’s a good idea to have us check it regularly. In addition to examining the battery itself, a technician will also inspect the terminals and cables for corrosion, damage, fraying wires and loose connections.  It’s smart to have us do it before any extreme weather changes are expected or before long trips. In this case, knowledge truly is power.

Are Modern Vehicles Maintenance Free?

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern vehicles are so reliable, they are virtually maintenance free."

Any good myth has some elements of truth. No offense to Winnetka Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Winnetka.

• Some vehicles in Winnetka no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts are up in the valve train that didn't even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they've always been.

So the maintenance mindset is still important for car owners in Winnetka if we want our vehicles to last a long time. The checklist may change over time, but there'll always be a check list. Your friendly and professional service advisor at {[ Shop }} can answer any questions you have about your vehicles maintenance schedule.

Watching Your Check Engine Light

Did you know that most of the cars driving around Winnetka, CA, carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Winnetka area have as many as 12 networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Winnetka drivers know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Winnetka drivers when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to A.G. Automotive & Diagnosis in Winnetka to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your friendly and knowledgeable technicians at A.G. Automotive & Diagnosis have special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you're Check Engine light is on.

(Ball Joint Replacement)

Every day that goes by, our bodies get a little more wear and tear on them.  Our vehicles have the same issue.  The older we get and the farther we travel, certain parts start showing some wear.  

Think of your hips. There are parts of our vehicles that are similar to them; just like hips allow your legs to pivot in several directions, your vehicle has similar parts called ball joints, and they connect your vehicle’s wheels to the suspension, allowing them to move together.  These ball joints get a good workout every time the vehicle is moving, especially on bumpy roads.  

Usually, these joints are well lubricated with grease, so they’ll work smoothly and quietly. They’re surrounded by a rubber sleeve called a boot, but that can wear out with age or exposure to moisture or debris.  When the rubber breaks, the grease can leak out, and damage accelerates.

When the ball joints start wearing out, you may start to hear clunking sounds that come from the corners of your vehicle.  You might hear it more clearly when you are turning a corner or going over a bump.  Over time, it might get worse.  Other signs are sloppy steering, vibrations when you’re moving and uneven tire wear.
If a ball joint gets extremely worn, it’s possible you can lose control of your vehicle, a dangerous situation indeed.

If you notice any of these symptoms, bring it to us so a technician can diagnose the problem.  If they determine you need a new ball joint, the technician will check the condition of all the suspension components.  We usually recommend if one of a pair of ball joints goes bad, the other is likely quite worn as well and should be replaced, too. In no time, you’ll be back on the road with an updated agile suspension that feels young again.
