Operation: Idler pulleys are used for timing belt routing and help to maintain belt alignment. Advice: Idler pulley bearings are of the sealed type and can not be serviced. Check to make sure that there is no wobble or play in the bearing and that it turns smoothly. If any play or roughness is found, the idler pulley should be replaced with the timing belt. Recommendations: Idler pulley
Operation: The tensioner pulley is used to maintain proper timing belt tension. Advice: Too much tension will cause a strain on any bearings involved. Not enough tension can lead to jumped timing. Tensioner pulley bearings are of the sealed type and can not be serviced. Check to make sure that there is no wobble or play in the bearing and that it turns smoothly. If any play or roughness is found, the tensioner pulley should be replaced with the timing belt. Recommendations: Belt tensioner Belt tensioner pulley
Operation: The water pump is sometimes driven by the timing belt. Advice: The life expectancy for the timing belt and the water pump are close to the same. If the water pump is driven by the timing belt, due to the lack of easy access, it is wise to replace them both at the same time. For more information select the "Job Info" tab under water pump lookup. Recommendations: Water pump Gasket sealant Antifreeze
Advice: Most timing belt jobs require the removal of all belts and some hoses in order to gain access to the timing components. While you have them off is an excellent time to evaluate the condition of the belts and hoses and replace as needed. For more information select the "Job Info" tab under belt or hose lookup. Recommendations: Belts Hoses Antifreeze
Operation: Both the camshaft and the crankshaft have oil seals to prevent oil from entering the timing area and contaminating the timing belt. Advice: One of the biggest reasons for premature timing belt failure is contamination from oil and antifreeze. Replacing the oil seals located behind the camshaft and crankshaft sprockets will help to ensure a long life from your new timing belt. Recommendations: Camshaft oil seal Crankshaft oil seal
