About Mercury Idler Pulley

Mercury is a division of the American automobile maker Ford. During the 1950s, it received great success. Mercury has plenty of quality vehicles and parts, such as the idler pulley. The idler pulley is essential as it is in charge of routing the timing belt so that it remains in the correct position.
Although Mercury has lots of auto parts with impressive performance, the idler pulley parts still need repair and maintenance after a long time of usage. It provides tension and helps guide the belt to the proper routing. The removal process for an idler pulley is as follows. First open the hood, next remove the engine drive belt, then locate the idler pulley. Finally, remove the mounting bolt for the idler pulley, and the pulley from the engine. We offer a lot of Mercury parts of great value. There are plenty of inexpensive and quality Mercury parts online.
