I have a 95gt Mustang, mods are in my sig. anyways this over heating problem started about two weeks ago, i replaced the water pump, coolant sensor, t-stat and i flushed the radiator, i stuck a hose in the top radiator hose inlet and water came out of the bottom inlet pretty fast, I then stuck the water hose on the bottom inlet hose and it took awhile for it to come out of the top inlet, but it eventually came out but it seemed like it took a little bit, also the upper radiator hose gets extremely pressurized and the right side of the radiator was cold while the left was hot, seems weird because yesterday both sides were hot as was the lower radiator hose and today it is cold, is the lower radiator hose supposed to be cold? and when it does overheat it doesn't boil water out of the reservoir or anything, anyways i need this fixed any insight would be great thanks guys.
UPDATE: i used a non contact laser thermometer and on the t stat housing is was 225 degrees and at the intake manifold right after the t stat housing it was also 225 degrees, the lower radiator hose is at 105 degrees and the upper around 190
and when i try to squeeze the upper radiator hose its extremely pressurized and its so hot that you cant touch it. i also checked the stock gauge by grounding out the sensor wire and the gauge went to full hot so that had to be working, when it over heats it right on the red line and when i shift it budges down a tiny bit than goes back up in between shifts or if i drive it another 100 feet, there is no water in my oil or smoke coming out of my exhaust. I am about ready to take this thing to pick and pull and watch them crush it
