My engine is not getting to operating temperature,its over cooling so, I installed a manual ball valve after the t stat but im scared that I might do damage to something if pressure rises too much, the only setting i haven t tried on yet is fully closed ( completely isolating the radiator ). I set it to half closed, no effect, 3/4 closed no effect, 8/10 closed no effect , why wont this coolant heat up? !!! I checked the thermostat in boiling water and confirmed the temperature with an infrared heat reader, the t stat opens perfectly. Lets go over everything: New nissan 85 degree thermostat new water pump new radiator fan always off heater core is clean with no leaks half the radiator blocked with a piece of cardboard topped up with coolant with no leaks And restricted flow to the radiator with a manual ball valve with half closed, 3/4 closed and 8/10 closed with no effects. Yesterday before I installed this manual ball valve I sat in traffic for about 20 mins and it made to 1/3 of the gauge with no fan or nothing, and something remarkable happened... I got heat in the cabin .... but once I started moving again its back on the C line -_-... crap

My temp guage needle would never make it to horizontal, even after a new thermostat so I assumed it was normal. Your situation is worse though, hopefully someone sheds light on it...
