1986-1989 honda accord,2.0L
Using a 12mm box end wrench, crack the bleeder screw located on the thermostat housing open to bleed the air out of the cooling system, ( this is done with the engine running, make sure that you keep your hands away from all moving parts ). If engine coolant starts coming out you will need to close the bleeder screw.
At the same time, keep an eye on the temperature gauge, if the engine temperature goes past 200 degrees F, turn the engine off and allow it to cool down, once it has cooled down open the radiator cap and add coolant if needed, start the engine again and repeat the steps described earlier, once the thermostat opens the engine coolant will circulate through the radiator and the engine temperature will remain at a constant 195 degrees F.
Inspect for leaks, make sure that the bleeder screw is tight and install the air intake hose back on the engine, take the car for a test drive, at your return inspect for leaks again, if you don't see any and the thermostat works properly you are done.
