Without a fully functioning timing belt, your vehicle would not run. The timing belt is an internal engine component that rotates the engine’s cam and crankshaft in sync and ensure each cylinder fires at the appropriate time. The timing belt is located under a timing cover and is in the front of the engine. It’s commonly manufactured out of high-quality rubber with nylon reinforced cords inside to extend the life of the belt. However, it is subject to incredible forces inside your motor and will need to be replaced eventually.
