Hi,

I need to change the drivebelt on my 1985 W201. The car has no AC. I am
wondering if it is sufficient to loosen the alternator so the tension of
the belt gets slack enough to get the belt off, or is it anything else I
need to take in consideration?

Thanks in advance for your reply,

This car should have serpentine belt.... one belt that loops through
everything. You need to loosen that big bolt on the tensioner...the one with
idle wheel... and then on the top side, you will see a brass like hollow
nut/bolt-like tensioner adjuster... loosen that and the tensioner will
release the belt.

While you are doing that, I suggest you replace the idle wheel... that black
cover in the center of the wheel pops off and you can then replace the
wheel... only $20... Your idle wheel probably already rattling.,, making
your engine sounds like a diesel.

Ok, great - thanks for your advice. Do you know of any images with
pointers to the tensioner and the "brass like hollow nut/bolt-like
tensioner adjuster"? I think I have an idea of how it looks, but would
like to be certain.

Naah, not really. It's got only 61 000 certified kilometers on the
odometer :-D http://borge.berg-olsen.net/

Thanks - I found it and have changed the belt now. What took the longest
was drawing the path of the serpentine belt on paper so I could get it
right. :)
