Q: where is the thermostat on a Honda Accord EX 1992 on 1992 Honda Accord

Have removed the metal housing where the top radiator hose attaches to the engine housing. There is a temperature sensor (?) also going into this metal housing. There is coolant coming out when removed but no thermostat there. Where is it and how do I remove it? What other parts need to be removed to get to it? Any other hints?

It is under the throttle housing air duct area where the bottom radiator hose attaches to the silver aluminum housing that is secured with two bolts (10mm head). After replacing the thermostat and gasket fill the cooling system and open the 12mm bleed screw to allow air to escape when refilling the cooling system (also turn the heater to full hot).

It is easy to assume the thermostat is in the other hose (as with most older cars). The air duct between the air filter housing and intake manifold does have to be removed to get easier access to the thermostat. Pour coolant in the radiator with the "bleed screw open" and you will see coolant push air pockets out the "bleed screw". When pockets of air are no longer present tighten the bleed screw and run the engine. Allow the engine to run until the electric fan cycles on and off, switch off the engine allow it to coo , top off coolant level in the expansion tank and readiator as required and you should be ready to test drive!
