Auxiliary Drive Belt Tensioner for the 2.5L 6-cylinder BMW diesel engine (M51).

This tensioner maintains correct tension on the ancillary drive belt, which drives the alternator, viscous fan, and other auxiliary components. The spring-loaded mechanism damps belt tension fluctuations caused by engine speed changes and varying loads, preventing belt slip and premature wear. It works in conjunction with the tensioner bracket assembly on the BMW M51 engine.

Frequently asked questions

What does the STC4168 belt tensioner do?

The STC4168 belt tensioner maintains correct tension on the auxiliary drive belt of the 2.5L 6-cylinder BMW M51 diesel engine. The spring-loaded mechanism damps tension changes as engine speed and load vary, driving the alternator and viscous fan without belt slip.

What are the signs of a worn belt tensioner?

A worn belt tensioner typically shows up as belt squeal, belt slip or a rattle from the tensioner area, especially on start-up. Left unchecked it can let the auxiliary belt wear quickly or come off, so replacement is worthwhile once symptoms appear.

Which model and engine does the STC4168 fit?

The STC4168 fits the Range Rover P38 (1994-2001) with the 2.5L 6-cylinder BMW M51 diesel engine. It works with the tensioner bracket assembly on that engine, so confirm you have the BMW diesel before ordering.
