BMW E46 330i Belt Tensioner Pulley
$69.99
The belt tensioner pulley keeps constant, correct tension on the serpentine belt that drives your alternator, power steering pump, and A/C compressor. When it wears out, bearing noise, belt slap, or a squealing engine bay are usually the first signs, and a failed tensioner can let the belt slip or come off entirely.
This tensioner pulley is built for the BMW E46 3-Series 330i with the 3.0L I6 M54 engine, matching the mounting and pulley dimensions of the factory setup so it bolts in without modification.
Made to direct OEM fitment specs with a durable spring-loaded housing and sealed bearing, it's a reliable way to quiet down belt noise and restore proper accessory drive tension.

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
