Tensioner for BMW 8 Series E31 (1991-1997)

Clear BMW chassis

Please ensure your correct model is selected

The belt tensioner is responsible for keeping proper tension on the belt at all times and during all running conditions. When the tensioner ages, it loses some of the spring tension and can allow the belt to slip if left unchecked. Turner Motorsport carries Genuine BMW and high quality aftermarket options to get you back on the road in no time.

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc). OEM replacement for BMW part # 11281720039 and 11281715630.
