A/C Tensioner & Pulley with Lever - Genuine BMW - E53 X5 4.4i 4.6is M62

This is the original BMW replacement tensioner, pulley, and tensioner lever for the A/C belt on the 1999-2003 E53 X5 4.4i/4.6is. This is an assembled piece that includes the tensioner as well as two deflection pulleys. Perfect for when a complete overhaul is called for. The tensioner is like a small shock absorber that maintains pressure on the belt. A loose belt will cause insufficient charging from the alternator, poor cooling performance from the water pump, and stiffer steering from lower power steering pump output. It might also lead to the belt slipping from the pulleys or premature belt wear.

This part is listed by BMW as BMW part number 11287515867 (11-28-7-515-867) and is described as Genuine BMW A/C Tensioner & Pulley with Lever for E53 X5 4.4i 4.6is M62 (1999, 2000, 2001, 2002, 2003).
