Can anyone tell me what is the correct thermostat for my 1981 c10 with a 6cylinder?
I haven’t taken the old one out yet but this was dads truck and he used to run cold stats or no stat at all then complain about the lack of heat in the winter any recommendations??
Also what size heater hose should this take? The standard 3/4 and 5/8? Or something else?
Thanks for your help

Also, does anyone have experience with the new aluminum heater cores? Good, bad, or indifferent?? Do the put out more heat? Are they better then the brass ones? Worse??
