The thermostatis in the water jacket at the gearbox or right hand end of the engine block at the top, follow the top radiator hose. Two 12mm bolts hold the jacket in place. You will need a "genuine" or genuine identical thermostat as the thermostat "floats in the gasket. I fell for the trick of buying a cheaper alternative but they don't fit!! You will aso need a new gasket. Take out the two bolts, remove the jacket, you will have to damage the gasket. Make sure you dont score the mating surfaces. clean up the joint faces. Tst that the replacement thermosatat worksby boiling in a pot of water first. Then fit it in the engine side, will only go in one way up. Fit the gasket put the top jacket on and bolt up. Refill with coolant and run till warm to check for leaks. Don't overtighten bolts as alloy threads.

They're extremely plentiful, in all the popular price ranges. No one's collecting them, and there's a good market for automatic-transmission Accords. the car in on the one you really want. NO

Where is the thermostat located on a 1984 Honda Civic?

is usually where the top hose from your radiator is conected to on your engine. has the best answers for '84-87 civics. the water pump thermostat is housed behind, and slightly lower then, the distributor, fallow the main lower hose from the radiator back to the engine block, there are two or three studs that hold a small houseing on over the thermostat, between it, and that large radiator hose, used a 12mm socket to removed them, and of course alwas replace the gaskat.
