This is the replacement hydraulic tensioner with pulleys for the main drive belt on the 1999-2003 M62TU engine used in the E39 540i, E38 740i, and 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 tensioner and pulley assembly is manufactured by INA, the original supplier to BMW for this part and other engine components. Since it is an OEM part, it conforms to the original design that BMW specified for the engines listed above. It comes with a two year warranty.
