i had a really bad overheating problem when i put pulley's on the car, now i have an electic fan, 180 thermostat, and a ron davis 4 core aluminum radiator and heat is a thing of the past. I agree with the solution to get another radiator, also what letter is the gauge on in NORMAL mine is at the L and no higher. my two cents.
