GMC Sierra 3500 Drive Belt Tensioner & Pulley

Why you drive your Sierra 3500.

Select Your VehicleYour GMC dealership isn't the only place to buy genuine or original equipment quality replacement parts for your Sierra 3500. When your GMC Sierra 3500 left the factory, it was destined for a driver who values longevity in their automobile. Obviously, you bought your Sierra 3500 because you understood you would be getting performance and rugged design both impeccably combined into one car, truck, or SUV. Anyone who drives a GMC knows that when it comes to repairing their automobile only the most superior replacement parts will do.

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

Your engine's accessories would not function properly unless your GMC Sierra 3500 drive belt tensioner keeps those belts tight. Your engine transfers power from the crankshaft to these accessories through the drive belts. But since they are traveling at such high speeds, the belt tensioners ensure the drive belts maintain a good grip on the pulley or else they will fly off; potentially leaving your car or truck without the use of its alternator, water pump, or more. GMC Sierra 3500 engines have drive or serpentine belt tensioners that should be adjusted regularly so that the belts can keep working properly.
