Re: Where is the thermostat on my 2.8 V6 engine 1999?
If it's the same as the 99 2.8 V6 in the A4, it's quite a ways inside the front of the engine. You have to remove a lot of the front of the engine and you'll find it partially hidden behind the timing belt tensioner. Foolish place to put such a part unfortunately, but at least on my A4 that's where it is.

if you have the 3.5 v6 izuzu engine the thermostat is a major job, requires removing upper intake ,because it is under not in front of like most thermostats. about 3-4 hour job depending what kind of problems you run into.
The thermostat is located in front of the engine, between V cylinder banks, for Audi A8 V8 4.2 Quattro Automatic. See pictures below:
Remove the thermostat housing (2 bolts) and the old thermostat. Note the orientation of the old thermostat (vent valve facing UP). Clean both thermostat housing and block surfaces and remove all traces of old gasket material. Install the new thermostat vent valve facing UP.
Before you replace check to test the car when idling. let the engine build up heat and test the engine temp. if the fan is not activating and shutting off accorrdingly then only you need to check for the thermostat. Since your car is overheating it means that your fan is not working at all or cutting off fast. Insuch a case you can go ahead. But if the fan is working fine and the AC is also switched on, then if the heat goes up, you will need to check for the radiator having any blocks. Check to see physically for any vent blocks on the fins reducing the air flow. even is any paper is stuck this can make the temp go up even if the fan is working. use a good pray washer to clean the radiator. if not flush your radiator and check for rust in system. if all this is not giving any result check for the engine management, for fault in the tining system. The fault should be here. but make sure before you drag to the traffic to test for a long duration idling with the AC put on.hope this is helpful. good day
run it and let it get hot (not to the point of overheating just let it warm up to normal or slightly above normal). put your hand near the upper radiator hose, if you feel not heat, touch it, be careful as it may be hot. if it is not hot at all but the engine is warmed up it is the thermostat, the thermostat is located where the upper radiator hose connects to the motor, usually a 2bolt metal fitting, if this is the case just replace the thermostat.
