The serpentine belt routing diagram for a 1992 Audi 100 CS with 2.8 liters V6 engine


CS = Crankshaft
Gen = Alternator
G = Guide pulley
T = Tensioner pulley
AC = Air Conditioning
PAS = Power Assisted Steering

sounds like the camshaft, or crankshaft position sensor is unplugged.

Water pump sits in the front of the engine top centerline. Look just below the coil pack. It uses the timing v-belt for operation so it takes a bit of mechanical know how to remove/replace (r&r) it, as the timing can be thrown off if the v-belt is not reinstalled correctly. Get past the timing belt, the water pump is r&r is just a few bolts away. I'm currently babying my water pump...the part is relatively inexpensive compared with an almost $500 labor charge (5hrs, dealer est.) to replace it. I'll be hitting up the dealer as my '93 Audi 90 CS Quattro is a daily driver. G/L

you dont need a diagram to see the timing marks on the top/bottom pulleys,just clean them off and run a piece of chalk around the perimeter.they are a bit obvious.....

I am not sure if you have the 90 or the 90 Quattro.

if the car did not travel too far,when the belt broke, and there is no major oil leak from bottom of engine, then you may be lucky not to have caused internal damage, therefor it can be fixed

On the low side charge outlet, right on the compressor itself

Replace the thermostat and flush the cooling system.

check the switch to turn on the air. it might be loose.
