it's located on the engine . or take it to the dealer . if you don't know what you are doing . those vehicle are expensive . if i were u . i take it to the dealer . Easy there! The thermostat is on top of the water pump and is a simple fix. You need an "O" gasket when you replace the thermostat.

It is cooling the engine off. Your Honda may be running slightly hot. I suggest you service the cooling system. Drain, flush, replace the thermostat, install a 50/50 mix of antifreeze & distilled water, bleed air from system.

Make sure antifreeze level is not low. And also "bleed" air from the cooling system. Look for bleeders where water hoses enter the engine. (might be one right on the thermostat housing).

What would cause an 1990 Acura Integra to overheat?
could happen if the thermostat is not opening, or if there's a pressure leak in the cooling system, insufficient cooling fluid, or a bad water-pump, a kink in a hose or blockage in the cooling-system. Anything that keeps the coolant from flowing in and out of the block or causes a loss of pressure. It isn't enough to just have coolant in the system, the sysem has to hold a head of steam as well. Otherwise the water will just get hot and blow out of the system.
