Mercury Timing Belt Idler Pulley provides consistent belt positioning that ensures the engine operates smoothly with its timing being accurate and with a low noise level. Mercury has had a reputation since 1939 of being sharply styled, with less noise in the cabins and bumps that are absorbed in the suspensions, a combination of comfort and value. Models that drivers adored included the Cougar and the Grand Marquis, and despite the fact that they were dropped by the year 2011, the brand remains bright because of the comfortable ride, spacious interior and luxurious touch. Although named after the swift messenger god of Roman mythology, Mercury emphasized smooth suspension, quiet cabins, and easy steering to deliver a relaxed and memorable driving experience. Timing Belt Idler Pulley is a smooth wheel that is applied to guide the timing belt and will maintain alignment, reduce slack, and eliminate wear so that valves and pistons can remain in position. In order to replace the Mercury Timing Belt Idler Pulley, one has to park, allow the engine to cool down, and disconnect the battery so as to prevent sparks. Eliminate covers and attachments, record routing of belts and release tension using a wrench. Unbolt the worn pulley, check the surface and stud, and install with a new Mercury Timing Belt Idler Pulley with any spacer installed, in the proper position. Add thread locker when required, screw, spin the wheel with the hand, replace the belt, apply tension, check the timing marks, turn the crank with the hand, replace covers, connect battery again then start the engine to confirm spinning.
