The function and purpose of Drive Belt Tensioner & Pulley.

Your engine's accessories would not function properly unless your GMC Sierra 3500 HD drive belt tensioner keeps those belts tight. Your engine uses a drive or serpentine belt to transfer the momentum at the crankshaft to the pulleys on your accessories. 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 A/C compressor, water pump, or more. GMC Sierra 3500 HD engines have drive or serpentine belt tensioners that should be adjusted regularly so that the belts can keep working properly.

Time has come... buy your replacements right now.
