Mazda CX-7 Timing Belt Tensioners and Mazda CX-7 Timing Chain Tensioners
Timing belt and timing chain tensioners keep the appropriate amount of tension on the belt or chain to prevent it from slipping off the gears, or putting too much pressure on the components which would cause excess wear.
If the timing tensioner fails while the vehicle is operating, the chances of damage to the engine are very high. On most engines (interference engines) when they are operating the timing system keeps the valves and pistons from colliding with one another. Should the timing system fail and the valve train stop, the pistons are likely to smash into the valves causing major damage. For this reason timing belt and timing chain tensioners should be replaced any time the timing system is serviced.
Servicing the timing system should be performed by a professional or mechanic with the knowledge and experience to do the job correctly.
