Unhappy 95 gt overheating update!

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

run a block check and see if it has a blown head gasket

that is a little warm on the intake a tstat housing. i know if u have a small leak in the system it can get air in it and throw the sensor all off therefore ur gauge will read wrong

If i had a small leak wouldn't i see water coming out somewhere? besides the possibility of a blown head gasket, even though the head gaskets are brand new.

I bet you put a head gasket on backwards...

what type of gaskets do you have? I think there is a way to look at the tabs and see if it's on the wrong way.

I put them the right way, the word front facing the top and front.

It sounds to me like you maybe have air trapped in the system. I had A similar problem with my 95. Take the radiator cap off and let it run for an our. And keep the radiator full of coolant. GOOD LUCK !!!!

After the car is warm turn on your heater full blast. Then grab the heater core lines. If there not hot you've got a blockage in the lines. If one is hot and the other is even slighty cooler your heater core is blocked. Also see if your getting any heat through the vents. I've had lots of overheating problems in my Bronco, I also wanted to see it crushed. I eventually had to replace the lower manifold because there was a void in a water jacket from the previous moron snapping a bolt and drilling it out crooked. Honestly I'm suprised it runs still. Good luck and let us know.

If not mistaken, the word "front" only is on one side so it will be front bottom on one side and front top on the other, that's how it was on my FelPro gaskets anyways...

But sounds like you payed pretty close attention. Good luck.

Matt.
