Good To Know

Q: Should the belt also be replaced with this assembly? A: A new belt is recommended whenever a tensioner is replaced, since worn belts and worn tensioners often share the same noise symptoms.

Q: How do I confirm this fits my BMW? A: Compare the OEM part number 11281427252 against the number on your current tensioner or look it up by your vehicle's model year and engine.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
