My 963 seems to run hot. On a 90 degree day it runs 220 or a hair over. Motor, water pump and thermostat are all new last year.Radiator was new a couple years ago. I put a band of steel inside the fan guard to close the tips of the fan. I did put a cat classic radiator in it which has four cores instead of five. The radiator has been pressure washed out this year also. Is this normal for the A models? Any suggestions? I've looked at custom aluminum radiators, kind of high but cheaper than another new motor.
