I replaced my radiator and thermostat after the old radiator cracked, but I used a Gates 180° thermostat instead of the OE 170° thermostat. Since installing it 3 days ago, I've only been able to get the thermostat to open once, when it was a sunny warmer day. Lately on cooler days (50°) the thermostat does not even open while driving uphill at high rpm (lower radiator hose stays very cool), and the engine doesn't seem to get very hot at all (the fan blows quite a bit though). Meanwhile since the thermostat isn't opening, it seems like my upper and lower radiator hoses are bulging with pressure since the coolant isn't circulating through the thermostat--can it sustain that? At the same time, I've noticed that even though the engine is warm, the heater takes awhile to put out heat, and sometimes intermittently puts out very warm heat or no heat. Could there still somehow be more air in the system causing that heater problem, or something else (vacuum?) Causing it? (I already followed the instructions using the air bleed bolt, etc to remove the air from the coolant system.)
have the same problem?
