DESCRIPTION
This pulley and lever attaches to the tensioner, ensuring there is enough traction from the main drive belt for the water pump and alternator to function. Something as simple as a loose belt can cause a failure of both the cooling and charging systems. Manufactured by INA, an original equipment supplier to BMW, and repackaged by IPD Germany.
HELPFUL TIPS
It's a good idea to replace the tensioner at the same time.
