the thermostat is located in the housing where the top radiator hose enters the engine. Note: there is also a brass screw on the top of the housing, this is to bleed the air from the cooling system when you replace the thermostat (or do other cooling system repairs)

Where is the thermostat located on a Plymouth Sundance?
The thermostat is on the top side of the engine. Follow the hose from the radiator to where it goes connects to the engine. The housing may have the coil bolted on to the outside, depending upon the model. On the top side of the housing is an Allen screw, which should help identify it, plus the temperature sensor is on it as well. The housing must be removed to change out the thermostat. The set screw must also be removed during refilling the system to allow air to escape.

Where the top radiator hose meets the engine there is a small hemi spherical housing, the thermostat's inside. The brass screw on top of this housing is where you bleed the air from the cooling system after replacing it and refilling the system. Be sure not to overtighten it after you screw it back together or you can snap the top off of it (brass is soft)

How do you locate and replace the thermostat on a 1998 Mazda Protege?
On almost all cars, the thermostat housing is right where the top radiator hose meets the engine itself. Drain 50% of the coolant,remove the housing bolts, remove the thermostat (note how it is positioned so you don't put the new one in upside down) scrape the old gasket material off the engine and housing, put new thermostat in, put new gasket in place, attatch housing with bolts (don't overtighten)...and refill with coolant. If there is a screw on the housing, start car, loosen screw until coolant starts to come out with no bubbles. This will bleed air out of the system so the motor doesn't overheat.
Where is the cooling system bleeder on a 1985 BMW 318i?
AnswerIt should be on the thermostat housing. Usually top of screw has a slit in it. Or rarely may have a nut shaped head. When loosening do not take bolt out all of the way.NOTE:A 1985 BMW 318i has an in-line thermostat. It has 3 hose fittings and connects to the lower radiator hose, the water pump, and the top of the engine. There is no screw or other adjustment on the thermostat housing. Some auto parts stores have a standard thermostat listed instead, so maybe there is a different engine configuration, but the in-line thermostat seems most common.
