thats right, cant have to much rad! I forgot to mention, i also swapped back to stock water pump pully when i was running hot. it helped some, but not much. After getting the new rad. i went back to the underdrive pully for good. I used to run the underdrive water pump pully in the winter, and put the stock pully on in the summer. I had like 4 different length fan belts..lol.
