What is Carbon Build-Up? How Does it Affect my Engine?

What is Carbon Build-Up? How Does it Affect my Engine?

What is Carbon Build-up? How Does it Affect my Engine?  Carbon build-up can be found inside the engine. Over time carbon builds up inside the engine from exhaust and fuel combustion. As the engine burns fuel, the layers of carbon build up causing the valves to stick. This can impede the valves sealing correctly when disposing of exhaust or intaking air into the cylinder.  Carbon can also plug up your fuel injector nozzles resulting in poor fuel delivery.  For example, when there is a fire in the chimney you can see soot start to build up on the inside walls. This is exactly what is happening inside the engine!  Oil travels a long road before it winds up in your vehicle. Gasoline from oil refiners such as Shell, Chevron, etc. mix their gasoline with their own kind of detergents. These detergents are formulated to remove or prevent the carbon build up in the fuel injectors and intake valves. This may differ though with a direct injec ... read more

Why Is My Car Hard to Steer?

Why Is My Car Hard to Steer?

Why Is My Car Hard To Steer? Why Is My Car Not Driving Straight? Why Is My Car Making A Strange Noise When Turning?    The answer to this question may be the result of a bad Tie Rod. The Tie Rod connects the Steering Gear or Power Steering Rack to the wheel of your vehicle. Over time, the pivoting joint of the tie rod can wear out, causing your tire to no longer stay in alignment. When you are turning your wheel a little bit and the steering feels loose, or the vehicle isn't responding to the way you are turning your steering wheel, this would be the reason. Other symptoms include: No steering at all or unusual steering  High pitched squealing noise (especially around turns) Uneven wear on tires Wheel alignment off             Our mechanics routinely check your tie rods when your vehicle comes in for service. To safely inspect ... read more

Do I have to Replace my Timing Belt?

Do I have to Replace my Timing Belt?

Do I Have to Replace my Timing Belt?    The simple answer is yes. Some vehicles have a Timing Belt, and others have a timing chain. These are necessary to keep the engine working properly and "in time". A Timing Belt is what keeps the engine valves and pistons "in time" with each other so that they don't collide. It is part of the internal engine system that creates a synchrony of movement between the Camshaft and Crankshaft to ensure that these engine valves open and close in unison during the Cylinder's in/out strokes.    The Timing Belt is rubber, so it does not last forever. In most cases, your manufacturer will recommend replacing as part of routine maintenance. This is about 70,000 miles, but every manufacturer is different. You can consult your owner's manual or come to our shop with trained professionals to ensure you are ... read more

What Happens When An A/C Actuator Goes Bad?

What Happens When An A/C Actuator Goes Bad?

What Happens When An A/C Actuator Goes Bad?   You might be thinking to yourself, what is an Actuator? We have had a few vehicles come in with this issue, that can range from a quite difficult job, to one not so intricate. Depending on your vehicle make and model this might be an extensive repair, in other cases, it could be a quick fix.    An Actuator or Blend Door Actuator, is a small electric motor in your vehicle that runs in forward and reverse motion to move the Blend Door/ Air Mix Door between fresh air and re-circulation modes, hot and cold air flow, and floor/defrost modes. The Actuator is what actually went out with one of these vehicles. So, the Blend Door was not swinging back and forth, causing the hot/cold airflow to be minimal. In another vehicle, we diagnosed a similar issue but the Actuator was working correctly. The ... read more
