2010 Honda Ridgeline Timing Belt Tensioner Replacement Cost

The timing belt tensioner, as the name implies, provides tension to the timing belt to ensure total contact between the teeth on the belt and the teeth on the camshaft and crankshaft timing gears. With the appropriate amount of tension from the belt tensioner, the belt and gears will remain aligned so the engine remains properly timed.

As the timing belt is installed this timing belt tensioner pulley is tightened to manufacturer specifications, and that places the proper amount of tension on the belt. It is bolted through the center into the engine, and the smooth side of the timing belt rests tightly against the pulley as it constantly rotates.

If the timing belt tensioner fails, there will be a very audible chirping noise from the front of the engine. This is because the tensioner bearing is no longer smooth. If it is not changed immediately, the engine will being running roughly, or stall completely. As a worst-case scenario, internal engine damage may occur due to slippage or breakage of the timing belt. The check engine light will illuminate on the dashboard in the event of total failure, and OBD trouble codes for misfires, crankshaft position, and camshaft position will be stored.

It is not recommended to drive a vehicle suspected of timing component damage. If the vehicle will run at all, it can quickly result in complete engine failure as described above.

Timing belt tensioner pulleys are replaced during a timing belt replacement service, either as preventive maintenance, or due to suspected failure. This means the average timing belt tensioner replacement occurs between 60,000 and 105,000 miles, depending on the manufacturer specified timing belt service interval.
