Mercury Mariner Drive Belt Tensioner & Pulley

Your Mariner is a prized possession.

Select Your VehicleThe vehicle in your driveway symbolizes the best in class compared to all the other cars, trucks, and SUVs on the road today. While it may not be difficult to buy replacement parts for Mercury vehicles, these days only the highest quality are required to fix your automobile. Mercury automobile owners have become used to a certain level of reliability when driving their Mariner around town. It's not every day that you find yourself in need of a replacement Drive Belt Tensioner & Pulley for your vehicle.

Don't go too long without fixing your Drive Belt Tensioner & Pulley... here's why.

One of the keys to maintaining an operational engine and full use of your accessories is keeping an eye on your Mercury Mariner drive belt tensioner. Your engine uses a drive or serpentine belt to transfer the momentum at the crankshaft to the pulleys on your accessories. Due to the pressure these belts are operating under, they could simply come off the pulleys unless the belt tensioner keeps them in contact; potentially leaving your car or truck without the use of its alternator, water pump, or more. Mercury Mariner engines should have their belt tensioners inspected and adjusted in order to ensure proper operation of the serpentine or drive belts.
