To all;

Those of you who are looking to change out your drive and AC belts with 4 zone climate control, you need a special tool to change out the AC belt. The good news is that its only $20.00. I also found both belts for a grand total of $30.00 at Pelican Parts. They are not OEM BMW Belts, but they are Cont-tech belts, which is an OEM supplier to BMW and are made in Germany.

Below is the special belt tool you will need.

You just have to take the fan out and upper radiate hose prior to pulling the fan, remove the tensioner pulley and spare pulley, replace them and then use the pulley by removing the pin to secure the drive belt in place. Then use the special tool on the AC pulley and to move the AC Belt in place.

It takes all of an hour.

If your at around 100k and have not done this, you should.
