Where is the thermostat on a 1992 Audi 100?

follow the lower radiator hose to where it is clamped to the motor...remove the part where the hose was clamped to, and Viola...also You should be able to find a shop manual at your local library with the right info...make copies as they are usually only in the REFERENCE section....good luck:)

Detach alternator, and servopump, and you see the thermostat housing from under the car.
