Restore Your Get-Up-and-Go (Fuel and Air Induction Cleaning)

You may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned.

As the hours pile up on your engine, carbon deposits can build up.  It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to.

While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions.

The fuel and air enter your engine through the fuel induction system and air induction system. Because of things like high operating temperatures and impurities, carbon in the fuel can leave behind dark, sooty deposits in the fuel induction system such as the fuel injectors and the throttle body. These and other residue reduce your engine's efficiency and performance. Our service center can use special fuel injector cleaners to remove those deposits from your engine.

The technician may manually clean some of the deposits and also put a fuel additive in the fuel tank that will get rid of other deposits that are still in the fuel system

Keeping the air induction system clean is also important.  A technician can use a liquid cleaner specially designed for the job. Not only can this improve your fuel economy, it may also reduce exhaust emissions and help your engine last longer.

Most gasoline now contains detergents that help reduce or prevent these problems, but direct injection is now being used in more vehicles that are more susceptible to clogging. Ask your service advisor if your vehicle could benefit from fuel and air induction cleaning.

Unlock the Secret (Malfunctioning Door Lock Actuator)

What a convenience power door locks are on a vehicle.  The latest don't even require you to push the button on the key fob; all you have to do is have it with you.  But sometimes there's a component of power door locks that can fail, especially when they are used several times each day.  Those are called the door lock actuators.

The actuator is an electric part that works with others (like motors and gears) to lock and unlock doors.  You can hear them work, sometimes with the little whirr of the gear or the quiet clunk of the lock finishing its cycle.  And it's good to pay attention to that sound because if it starts to sound different, it could be a signal that your lock is on the brink of failing. Another sign of a failing power door lock actuator is they start working intermittently or quickly and erratically.  The driver's door is often the first to start acting up since it's the one that usually gets the most use.

When you start to notice these signs, consider a visit to your service facility to get your vehicle checked out.  If you wait too long, you may find yourself getting locked out of your vehicle. Many vehicles do have mechanical keys available as a failsafe so you are at least able to get inside.  Some of them are hidden inside the key fob and you should know how to access them.  Check with your owner's manual or ask your service advisor.

It's extremely inconvenient to have to unlock your vehicle with the mechanical key, then get inside and unlock the other doors. It's even more inconvenient if you have passengers in the rear seats.  And that doesn't even count having to go through the same thing to lock the doors when you arrive at your destination.

There are many things that can cause power door locks to malfunction, but if it turns out to be a power lock actuator, the most common remedy is to replace it.  Some are easier for technicians to reach than others, depending on your vehicle's design.  But once your locks are working again, you might think you've found the "key" to happiness!

Steering You Right (Power Steering Signs of Problems)

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is.

Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid.

Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for:

• A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn.
• Signs of hydraulic fluid leaking, such as wet spots under your vehicle.
• The smell of burning oil while you're driving.
• Steering wheel hard to turn or vibrating.

If you notice any of these signs, it's a good idea to have a trained technician check them out.  They may be signs of:

• Power steering pump going bad
• Steering rack or gear seals wearing out, causing them to lose hydraulic fluid
• Broken fluid hose
• Defective power steering cooler
• Loss of pressure in the power steering gearbox
• Worn out steering pump belt
• Failing electric power steering motor

It's important to have these checked out sooner rather than later. You need to be able to steer properly in order to drive safely. Plus, some of these problems can cause more serious—and expensive—damage if they're not fixed.  Power steering is a wonderful feature of your vehicle.  Keep it well maintained and it will steer you right.

The Light Many Drivers Fear (Check Engine Light)

Ask just about any driver about one thing they fear seeing inside their vehicle and they'll say it's the Check Engine light coming on. You know, that little light on your instrument panel that is in the shape of a vehicle engine, often accompanied by the words Check, Check Engine, Check Engine Service, or Service Engine Soon.

There are so many different reasons that light shows up, from something as simple as a loose gas cap to a more serious problem that requires immediate attention. 

The Check Engine light comes on because a component of your vehicle's onboard diagnostics system is telling you something isn't operating normally. Your vehicle has a lot of sensors built in, all tied together by computers.  When the sensors are showing that things somewhere aren't functioning the way they should be, they alert the vehicle's diagnostic computers and tell you something's amiss.

The simple rule is if the Check Engine light is on steadily, it's something you should have checked soon but it's not urgent.  If it's flashing or has turned red or orange instead of yellow, get your vehicle checked out as soon as possible.  If you don't, you may be facing some costly repairs.

Here are a few problem areas that may trigger your Check Engine Light. 

• Something's wrong with the emissions equipment.  Maybe too much fuel is getting into the catalytic converter, or the exhaust gas recirculation system isn't working right.  Because some of these components are expensive to replace, it's worthwhile to have a technician look at your vehicle sooner rather than later.
• Your ignition system isn't working right.  That means spark plugs, coils, and wires.  If your engine is misfiring, that could translate into an illuminated Check Engine light.
• The transmission isn't behaving the way it should.  The transmission works in tandem with the engine, so if a sensor sees something wrong there, it will tell the vehicle to turn on the Check Engine light.

As you can see, there are many things that can cause the light to come on, and when it does, it really is a good idea to find out why.  When you bring your vehicle in, we have an electronic device that can read a code or multiple codes stored in your vehicle's computers.  That will provide the technician with clues pointing to the cause of the trouble and helps pinpoint where that trouble is.
