Easy on the Wheel (Power Steering)

Steering a vehicle these days doesn't take much effort, but if you got behind the wheel back before power steering was invented, you'd need to practically have the strength of Hercules to turn the wheel.   

The first power steering systems widely available changed everything.  Chrysler introduced its Hydraguide power system in 1951. The "hydra" was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most "natural" steering experience of power systems.

Recently, automakers have turned to electric power steering.  It gets its power from the car's electrical battery and charging system and uses an electric motor to turn the wheels.  Since it's not powered by the mechanical energy of your vehicle's engine, electric power steering increases fuel economy.  Electric power steering also doesn't require hoses and fluids, meaning there are fewer things that can go wrong.  That means less maintenance. 

There's a third system that combines both of the others, called electro-hydraulic power steering. In this system, the hydraulic power steering pump is powered by an electric motor and, some say, gives the driver that more natural feel of hydraulic systems.  

Because steering is so important for the safe operation of any vehicle, it's essential to make sure yours is working the way it should. Different types of systems require different kinds of upkeep. Regular, scheduled maintenance according to the manufacturer's recommendations should help keep your steering in top shape so you can avoid any sudden steering failures.  Bring your vehicle to us so a technician can inspect your steering system.  And, of course, if you notice any steering problems, make an appointment right away to have those issues looked at.  Now that's one stop that makes sense!

A Clean Connection (Battery Cleaning)

A clean connection is a wonderful thing.  Think of a good cell phone signal or an airline connection with ample time and short distance to the next gate. Good connections are also important for your vehicle’s battery, and one secret to that is to make sure it’s periodically cleaned.

If it’s been a while since you have had any service to your battery, bring it in so we can inspect it for any corrosion that might have formed.  Corrosion on the battery terminals will affect the connection between the battery and your vehicle’s electrical system. The amount of corrosion you can expect can be influenced by such things as the kind of climate you live in (dry or humid, warm or cold), if there’s lots of salt on the roads and how old your battery is.  

We have tools and chemicals to safely remove the corrosion for an optimal electrical connection. In order to reduce the amount of corrosion re-forming on the battery, we’ll apply a special protective coating.  

It’s also important to have your battery tested, especially if it’s more than a few years old or hasn’t been tested in a while.  Our equipment can measure how well a battery holds a charge and how much more life you should expect from it. We can discuss when you might expect to buy a new one, since a battery is definitely the kind of thing you don’t want to have fail you when you’re least expecting it.

Making Sense of the O2 Sensor (Oxygen Sensor Replacement)

As you know, today’s vehicles rely on a lot of computers in them to keep them running clean and efficiently.  Those computers depend on information delivered by several sensors throughout the engine and exhaust system.  And one of the most important is the oxygen sensor.  

Known as the O2 sensor for short, it looks for too much unburned oxygen that has made it into the exhaust. That signals something isn’t right with the engine’s air-fuel mixture.  The sensor sends signals to the engine’s computers, which can then make adjustments to make sure the engine is running as it was designed to.

Some vehicles can have several O2 sensors, and since they can measure oxygen at various points in the combustion/exhaust process, the computers can pinpoint where the problems lie.  For example, an O2 sensor can detect how much oxygen is coming out of the engine’s combustion chamber, and another one can measure oxygen coming out of the catalytic converter.

As you can see, it’s important that those O2 sensors are working correctly.  If they’re not, the computer is getting bad information.  Garbage in, garbage out. That can result in lousy fuel economy and excess pollution coming out of your tailpipe. It can also affect your vehicle’s performance.  Sometimes your Check Engine light will illuminate when one of your O2 sensors goes bad.  Or you may notice your engine misfiring or idling roughly. 

If you notice any of these symptoms, bring your vehicle on in, and a technician will pinpoint the trouble spot.

Braking Good (Brake Drum Replacement)

Maybe your vehicle feels like Breaking Bad.  In other words, when you brake, things are bad.  You may find it takes you a longer distance to stop, you feel a vibration, or it’s pulsating when you depress the brake pedal, or perhaps your vehicle pulls to one side.

Those can be symptoms of failing brake drums.  While a lot more vehicles these days have disc brakes, many vehicles still have brake drums, almost always in the rear wheels. The drum is a cast iron shallow cylinder that surrounds the other parts, including curved brake shoes that press pads against the drum to slow you down or stop the vehicle.

Any time you have things going wrong with your brakes, you should get them fixed soon.  Safely operating any vehicle depends on having the brakes be able to slow and stop you dependably.  It can make the difference between avoiding a collision and having one. 

When you bring your vehicle in, a technician will inspect your braking system. Depending on the wear, drum brakes can be resurfaced or replaced. Sometimes it’s cheaper to replace the drum than to resurface it.  It’s important for all the other brake system components to be inspected first and all worn parts replaced.  

Most of the time, when you have your drums resurfaced or replaced, the brake shoes should be replaced at the same time. You have brakes at each end of your axles, and the same brake service should be done at both ends so that both sides can have consistent, even stopping power. 

Your brakes can save your life.  If their braking power is bad, you owe it to yourself and others on the road to let us help make them good again.  Good and safe.
