BMW N52 Engine Serpentine Belt Tensioner Pulley Kit | E81 E82 E87 E88 E90 E91 E92 E93 E60 X1 X3 X5

BMW N52 Serpentine Belt Tensioner Kit – Complete Replacement for Drive Belt System

The serpentine belt is responsible for transferring power from your engine to critical accessories like the alternator, A/C compressor, power steering pump, and more. Over time, the tensioner and pulley can wear out, leading to belt slack. This slack can cause the belt to slip off unexpectedly, risking serious engine damage — especially if it gets pulled into the crankshaft seal.

Our Complete Drive Belt Tensioner Kit is designed to reinforce your engine’s accessory system, restoring optimal tension and preventing catastrophic failure. This all-in-one kit includes everything you need to get the job done right.

• Restores Smooth Engine Idle – Eliminates tension-related vibrations and squeaks
• Improves Accessory Performance – Ensures the alternator, A/C compressor, and power steering operate at full efficiency
• Complete Kit – Includes a replacement belt tensioner, pulley, bolt, and drive belt for a full fix
• OEM Fitment – Precision-designed to match factory specs for a snug, secure fit

FITMENT: Compatible with all BMW N52 engines, including: E81, E82, E87, E88, E90, E91, E92, E93, E60, X1, X3, X5.
