Continental is the OEM supplier for the stock serpentine accessory belt on your M52TU or M54 engine. They are also the OEM for many other components on your entire car. This extensive kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually and you get OEM-quality over any 3rd party aftermarket brands.

Included in the accessory belt and tensioner kit is:

main drive belt, 11281706545
A/C belt, 11281437450
mechanical belt tensioner with pulley, 11281427252
A/C belt tensioner with pulley, 11287512758
deflection pulley, 11281748130
mounting bolts

This kit fits cars with the mechanical belt tensioner only. Generally this is all cars up to 2002 model year but you may want to double check your car and match the picture to the tensioner on your engine. The hydraulic tensioner has a miniature shock absorber on the belt tensioner. You can also tell early from late by the A/C belt. BMW changed the spec from a 5-rib belt up to 2002 to a 4-rib belt from 2003 onwards. This kit does not fit any M56 SULEV engines.

This item fits the following BMWs:
1999-2002 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi
1999-2002 E39 BMW 525i 528i 530i
2000-2002 E53 BMW X5 3.0i
1999-2002 Z3 BMW Z3 2.3 Z3 2.5i Z3 2.8 Z3 3.0i
