Timing Belt Service
If you 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 manufacturer recommends that you replace the timing belt at 60,000 miles, don't forget that this also means replacements at 120,000 miles, 180,000 miles and so on.
Preventative maintenance are the words to keep in mind for saving money and keeping your car on the road longer. As an integral part of your car’s engine, timing belt must be maintained on schedule in order to avoid very damages to your engine. A broken timing belt, or a timing belt with missing “teeth”, will cause the engine to stop and likely permanent damage to the valves, camshaft, cylinder head, and cylinders.
So to avoid the need for a new engine, which could cost thousands, follow the scheduled maintenance for timing belt service. And the very best way to ensure that your timing belt is going to work properly for the life of the scheduled maintenance is to replace all the components it comes in contact with, as well as the various oil seals that lay underneath the timing cover.
The timing belt propels the camshaft or camshafts, the crankshaft, and the water pump (if it is attached to the timing belt). These sprockets very accurately propel the shafts so that valves open and close as the cylinders move up and down. Sprockets do not have bearings and do not wear easily, thus we don’t recommend replacing them. Idler pulleys pull the belt out of the way of other components. They are just a means to make more space. Water pumps are also commonly propelled by the timing belt. The timing belt tensioner is a pulley that adjusts tension either mechanically by spring or automatically with a pneumatic pin to keep tension on the belt and avoid slippage. The bearings in these pulleys dry out and can overheat and freeze, causing the belt to snap. Automatic tensioners also dry out and lose tension, but we do not always recommend replacement.
