Z4 Maintenance.

My car has 63k miles. Should I change the serpentine belt? Also, when should I change the transmission fluid and can you guys tell me what maintenance should I do at 64k miles?

Auto or manual ?

Belt - depends, you should check it.. I had 40k on mine and I went to an indy shop, the guy checked it for free and told me come back in another 10k to check again.

If you have someone reliable that can check for you

Personally I'd change the belt, ie, they not only age with mileage, but also with time, especially if you live in a hot environment, and/or, the car gets parked out in the hot sun... rubber is rubber and heat and time are not its friends. Besides: the belt is cheap, and the swap is straightforward.

Thanks. Also, does anyone know the diagram for the serpentine belt for my car? It is a Z4 2007 3.0si, with a steptronic(manual or automatic).

Maybe it's "cheating"... but I've always just drawn a picture of the belt and the routing, before I take the old one off... and use that pic to route the new one. ;-)

I'll use my camera, since trying to draw the picture is kinda hard to see. Thanks!

+1 .. to put the new belt on, plan on compressing the tensioner pulley almost to fully compressed, ie, a long breaker bar is to your advantage, likewise, positioning it so that one can get the necessary (angular) swing to compress the tensioner is necessary - sometime from above is the correct approach, and sometimes from below... one of the problems I continue to run into is: it seems to take less compression of the tensioner to remove the old belt than to put the new one on - so the position that worked for taking the old one off, sometime (all too often) isn't the appropriate one to put the new one on... take your time, and a 2nd set of hands can be quite useful.

As good as a drawing, maybe better... but either is better than a manual: case in point - my 2.3 Z doesn't match any manual I've seen - the manuals all show an additional tensioner that isn't there - hence the routing is different. Good luck.
