Performing A Brake Job On A Chevy Volt
There is nothing special about pad and rotor replacement on the Volt. The only precaution is to make sure the High Pressure Accumulator (HPA) is depleted.
Active Wheel Speed Sensor Diagnostics
There are two “types” of sensors generally found on the modern car – the passive speed sensor and the active speed sensor. They both perform the same function, but work entirely different. The passive speed sensor uses a magnet with fine copper wire wrapped around it to create its own alternating magnetic field. The polarity changes from positive to negative as the tone ring passes by the magnetic field. This frequency changes with wheel speed.
Judging Brake Pads: Do You Trust Your Pads?
Buying a quality brake pad is like buying medicine. When you are buying a legal drug, you are not just paying the cost to manufacture, package and market the pill. The bulk of what you are paying for is research and development. The same is true for brake pads.
10 Alignment Tips To Increase Productivity And Profit
Tires are not perfect! Like every part on the car, tires and wheels are made within tolerances. These tolerances include runout and radial force variation. The changes in uniformity and stacked tolerances in the tire and wheel can cause a steering pull. You can try rotating the tires to cancel out the pull or at least move the worst tire to a non-steering axle. But, during the next rotation, the pull could return.
Catalytic Converters: New Diagnostic Strategies
Catalytic converter failures on today’s vehicles are rarely caused by defects in catalytic converters. Most catalytic converter failures can be traced back to problems caused by what happens in the combustion chamber. Almost every part on the engine determines how long it will last. It could be a faulty line of computer code that pulses an injector too long, or it could be a stuck piston ring that allows oil to be sucked into the combustion chamber. These little details can limit the life of a catalytic converter.
Alignment Service On A 1998-2006 BMW 3 Series
The BMW E46 was the best selling generation of the 3 Series. And while the rear-wheel-drive sports sedan is one of the more complicated cars to align, it offers many service and repair opportunities. The front suspension is a strut design with the familiar sickle-shaped control arm that was introduced on this platform in 1983. The rear suspension carried over from the E36, but it has a unique rear trailing arm design.
Diagnosing Exhaust Gas Recirculation (EGR)
Exhaust gas recirculation is the dilution of the air/fuel mixture to control amounts of exhaust gas. Since exhaust gas does not burn, this lowers the combustion temperatures and reduces NOx emissions from the engine. At lower combustion temperatures, very little of the nitrogen in the air combines with oxygen to form NOx. Most of the nitrogen is simply carried out with the exhaust gases.
Cooling System Tips For The 6.0L/7.3L Powerstroke Engine
One of the most overlooked preventive maintenance items in a diesel engine is the coolant system. Maintaining the coolant system is just as important as an oil change – in fact, the coolant condition in a diesel engine may even be more important than in a gasoline engine.
Breaking Down Why Engine Oil Breaks Down
First off, all oil breaks down. That generally will include base stocks and additives. Without focusing on performance characteristics, the most significant difference from one oil to another is how quickly breakdown occurs. Although there are many factors that contribute to the breakdown of an oil, heat is one of the most important.
Great Bear Auto Repair’s Mama Bear Puts Her Own Touch On Long-Time Family Business
Audra Fordin, the fourth-generation owner of Great Bear Auto Repair and Auto Body Shop, in Flushing, NY, is known as “Mrs. Fix It.” Like many owners in the business, Fordin learned about car repair as a child spending her weekends and vacation days taking it all in at the shop, then run by her father, Bill Fordin. “When I was small, I was fortunate to work with both my dad and my grandpa. I learned from the best, first hand,” she said.
