Fan belts 95 940

Can someone please tell me how the 3 fans belts are configured on a
1995 940 turbo? The belts currently on the car are as follows - the
first belt (closest to the engine) runs the water pump and the power
steering. The second belt (middle) just the alternator and the third
belt (furthest from the engine) just the air conditioner. I seems to
me that there should be more than one belt running the water pump
since this is the most critical of the 4 componenets (Water pump,
power steering, alternator and a/c). Does anyone know the proper
configuration for the 3 belts?


Thanks

It is no more critical than the alternator and drives both of the critical,
fluid-based components. If you feel that the water pump merits it's own belt
drive, then you should change to a diesel version of your car, in which the
water pump is driven from the cambelt. Do you have an owner's handbook for your
car? In it you will find most of the interesting details.

Cheers, Peter.

The need for two belts driving an accessory is to do with how much
stress that accessory puts on the belt. The thing that is capable of
putting most load on a belt is the alternator when you are running
with high-load electrics turned on, which is why you will sometimes
see two belts driving this. The water and steering pumps or the AC
compressor are comparatively light loads and really don't put that
much stress on a belt.

If your concern is about the risk of a belt breaking, the belts should
be checked for wear, damage and tension at each 12k mile service. A
broken belt is a rare thing these days, but as they have to be removed
when the cam belt is routinely changed it makes sense to change the
accessory belts as well.

How they're routed on your car is how they came from the factory.
However, I've seen a couple of cars where the middle belt has been
exchanged for a longer one that also goes around the second water pump
pulley groove. I have no idea how much longer this belt needs to be,
but if you're worried about it, you may want to look into this for peace
of mind.
