Cadillac STS Drive Belt Tensioner & Pulley

Why you drive your STS.

Cadillac automobile owners have come to expect a certain level of performance when driving their STS around town. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs on the road today. It's not a regular occurrence that you find yourself in need of a replacement Drive Belt Tensioner & Pulley to fix your vehicle. You bought your STS because its a reputation for strength and American engineering struck a chord inside you; so why would you settle for second best when it comes to great quality auto parts?

Why Drive Belt Tensioner & Pulley replacement is so important.

One of the keys to maintaining an operational engine and full use of your accessories is keeping an eye on your Cadillac STS drive belt tensioner. Your engine accessories are essentially siphoning power from the crank and sending it to your accessories through a drive or serpentine belt. 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. Cadillac STS engines have drive or serpentine belt tensioners that should be adjusted regularly so that the belts can keep working properly.
