What is this? This is the inspection of one of the car's most important belts — the notched rubber belt known as the timing belt. This belt allows the crankshaft to drive the camshaft, which in turn opens and closes the valves. Without this belt, the engine can't run.
During the inspection, your mechanic will look for signs of wear, such as cracks, shredding or excessive slack. To determine if your timing belt is loose, ask your mechanic to check the tension. All cars have ways to adjust the timing belt tension. Some cars have self-adjusting mechanisms, while others need to be adjusted manually. It's a good idea to check for signs of oil leaks from the adjacent seals as well. This can damage the belt and considerably shorten its life.
When? We recommend this service every 100,000 kilometres as a preventative measure unless directed to do it sooner by your mechanic.
Why do I have to do this? This AC Delco video explains what happens if your timing belt breaks. The short answer is, your vehicle won't run without it! And, in some cases, if it breaks it can damage the engine leading to the need for a new one. So, even though the timing belt is an expensive maintenance item it does cost less than an engine.
Car Care Tip:Find out if you have an interference or non - interference engine. Ifyou have an interference engine, don't try to squeeze every last mile out of your timing belt. Change it at the recommended interval. If your vehicle has a non-interference engine it's not vital the timing belt not break - the worst that will happen is being stranded on the side of the road.
Also, some vehicles have timing chains. This is different from a timing belt and can't be serviced.
