After A/C Add On Engine Overheats Really Bad

George R said

Sounds like there's air trapped in the cooling system. If so, it'll create steam, and that will make the engine run HOT.
Fan shroud is a MUST. Nothing wrong with a flex fan. I have a 11.5-1 compression 440 that runs so cool, if I run it without the thermostat, the gauge won't move from the "cold" pin, and it has a stainless flex fan.

Good Luck!

very bad idea to run without thermostat, water circulates too quick to cool the back of the engine, can cause rear cylinder damage

nothing wrong with flex fans, but they definatly won't move the air a clutch fan will that has a proper thermo clutch on it

for the most part flex fans will keep a car nice and cool, but ma mopar put the parts that are on our cars for a reason; it worked and worked good
