The 90 is still is overheating. I am at a loss. I cant keep driving over to where it is working on the car doing the same **** every time with no changes. I seriously dont see the root of this problem. PLEASE offer any and all ideas, I need help here.
Here is the scenario. I can start the car and it will run fine for 15-20 minutes. It doesnt get hot to fast or stay cold to long. Seems to be equal to my 92 3.8s warm up time.
The upper radiator hose will start to get warm around the time the dummy gauge is at the M in norm. I also have pressure in the system. From here it will slowly keep creeping up until it hits the N in norm. Not fast by any means. When I hit this point I turn the car off because I know that it will just continue on its way up.
The radiator never really gets hot, almost like there is no flow. There are NO air bubbles. I can open both the vent on top of the engine and the radiator cap and I still have full coolant levels.
I have replaced...
New water pump
new 195* thermostat
16# radiator cap
flushed coolant about 3 times
Compression checks out fine. The oil is still as clear as when I put it in; no water in it. No knocks or pings.
Im sure the gaskets went on the right way.
Can that stop leak plug up the passageways in a block? The guy I bought the car from liked that stuff more than he should have. The radiator was plugged from the stuff, thats why I replaced it. If so how can I clean it out? Pressure washer? Chemicals?
Any other ideas? Im at a loss here.
