Replacing a thermostat on a 1989 Audi 100 should take an estimated 15 minutes. First you will need to disconnect the radiator hose by taking off the two clamps.

Yes your thermostat is working if it is drawing coolant after about ten minutes.

If it starts within ten minutes your thermostat is working fine

It could be that you are low on coolant, but if that is not the case, your thermostat may be stuck open. After the vehicle has been running for about 15 minutes, put your hand on the top of the radiator. If it is not too hot to touch, your thermostat should probably be replaced.
