06 X3 Belt Tensioner

I recently bought an 06 X3, it seems the belt tensioner needs to be replaced due to unpleasant sound it's generating.

Repair shop says due to a design change, all parts / belts will need to be replaced, 10 parts, for a total cost of more than $900.

Im new to BMW's but it seems like there should be an aftermarket spring loaded tensioner available. Vehicle has 126k and the belts were replaced less than a year ago.

Question is, is there an aftermarket part and is it an acceptable idea to use it in this case?

Please advise.

Short answer:yes. Google bmw wholesale parts or check ebay or amazon. You might as well get both the A/C tensioner and the accessory belt tensioner since you are going to be in there. I just helped my brother change his acc. tensioner and it took less than a half hour. He got his part at Autozone for $60.

I second the above. You need a spring-loaded belt tensioner, not the hydraulic one that BMW migrated to (that needs the extra parts to retrofit).

It's actually just the pulley that needs replacing usually as the bearing grease dries up. You can get the required Dayco or Gates pulley separately for less than $20 - but not from BMW.

Here's a post that talks about the Dayco and Gates pulleys, and which one may have the better bearings.

http://www.bimmerfest.com/forums/sho...08&postcount=6

Note that replacing the pulley in a mechanical tensioner instead of the whole thing is Option A in saving some money.

To save even more, you can choose Option B which is using a pick to carefully remove the oil seal on the worn pulley, cleaning it out, and repacking with fresh grease.

But be prepared to find that the source of the noise could be something else - such as the water pump. Once the belt is slackened off those things can all be checked.

(It's a good idea to take a pic. of the belt routing before removing it. Reassembly isn't always intuitive.)

Get the pulley for the mechanical serpentine belt tensioner. I replaced mine with a Dayco 89133 unit that I got from Canadian Tire for $16. It is made by INA iirc.

$900 is crazy..
