Another Overheating Mystery
After 5-10 minutes 400 sbc is heating up to 220° I turn off and notice the radiator feels cool. Have replaced thermostat, (180°) got air out by filling and running even jacking up front end. Temp sensing unit from classic instruments does not have adapter that can trap air. Laser thermometer shows temps are reading correctly. I plan on replacing water pump next. I just finished rewiring entire truck and installed 4 row radiator because I installed air conditioning
Thought I had air pockets but I've done everything to get the air out. Any suggestions?
