Having problems with your 1990 Honda Civic ?
I need to replace the thermostat, but I can't find the thermostat housing. It's a 1990 honda civic ex.
I can't tell if it's by the upper or lower radiator hose.

\015\012The thermostat housing is on the passenger side of the engine head near the top. Check your hoses as there are some under and behind the carb/intake that can become problematic and leak coolant. If this has been helpful please leave positive feedback. Thanks, SnugglePants
