Timing Belt Tensioner Replacement
The timing belt tensioner is what applies pressure to the timing belt, keeping it tight and running smoothly. When something goes wrong, it is often the tensioner that is the cause and not the timing belt itself.
If the tensioner breaks, the timing belt can slip or break and the split second synchronization of engine parts is lost and the damage could be catastrophic.A broken timing belt can cause the pistons to collide with the valves, potentially bending or breaking them, as well as the piston, cylinder and crank-shaft.
