A vehicle’s engine is responsible for converting energy into mechanical motion. It accomplishes this through the combustion of fossil fuel with air, both of which are released into a combustion chamber by several valves. The resulting force of the expanding gases pushes a piston downward. Subsequently, the crankshaft coverts the downward movement into a rotary motion that is then distributed to other vehicle components. This process relies on precise timing and accuracy to be successful. The valves must release the air and fuel into the combustion chamber at the right moment and remain closed while the fuel is being compressed and the piston is being pushed downward. Lastly, an exhaust valve must open to allow the unwanted exhaust gases out. The process of opening and closing the valves is done by a rubber timing belt.They should also be replaced at the first signs of wear—a broken timing belt will not only make your vehicle inoperable, but it can cause serious damage to other components in the engine.
Timing belts fail without warning and on some vehicles, are almost as hard to check as they are to change. In most cases, your only protection is to change the belt at the recommended intervals. Timing belt replacement is not a cheap job but it is far less costly than the alternative. Unfortuantely there’s no good rule of thumb for how long a timing belt witll last since the expected lifespan of your timing belt is specific to your car and engine configuration, usually between 60,000 and 100,000 miles. Stay proactive and change your timing belt based on what your car’s manufactuerer recommends.Your timing belt will make an average of 30 million revolutions each year—make sure it makes another 30 million next year by coming to Auto Care Experts!
