I've now tried different t-stats and drilling a hole in one of them. After touching some of the hoses, ive notice the top radiator hose is really hot but the radiator was cold. So I'm guessing that my radiator is clogged. Now knowing that i might have to replace the radiator, would it be possible to create a hybrid system using a open cooling system radiator in a closed system or does that not really work.

I first notice it about a week ago driving at highway speeds, so i had it towed home and it sat in my driveway, after replacing the thermostat in , let the air out of the system and it stated to overheat at city driving speeds. How i know its overheating because coolant was forcing its way out of where the line attachs to the coolant tankon the bottom and the gauge needle was in the red.

Ok i've done a compression test and each cylinder reads the same psi and i have changed the tank and cap with the 703-1396 cap and its still overheating, is there anything else I'm over looking.

1.whats a spal controller? 2.i've not tried a pressure test yet, ill try that in the morning. 3.my coolant tank lid is in good condition. Where is the coolant leaving the system when it overheats? Not the coolant bottle cap? The coolant forces its self from the bottom of the coolant tank Then the tank is bad...... Replace the tank and install a 703-1396 cap on it and go from there. I'll try that.

My 89 Mj keeps overheating. I can drive about a mile before the needle is in the red even with the electric fan on. I've replaced the theromstat, water pump, fan relay and fan switch sensor. I can't figure out what might be causeing this, feed back or ideas would be great.
