cooling issues revisited
now if i turn my a/c on max or start getting on it a bunch or even try to drive somewhat spirited my car starts to heat up to about 220 deg ish according ot my guage and the hand held obd2 scanner.it will get hotter but i keep a eye on it all the time.now both my low speed and high speed fans work and turn on.my cooling system is fully bleed and there is no air in the system and i have replaced the tstat and coolant.coolant level never drops and stays full and i am about 95% sure nothing is cloged.i have only one idea of what it could be and want some opinions from you guys.i found out from the casting numbers on my waterpump that it is a 2006 ls2 GTO waterpump.only reason i know that cause the problem i had trying to get my tstat.i am guessing that either the pump has a higher gpm or a smaller pulley than a normal ls1 waterpump.i ended up replacing the serpintine belt with the one called for the GTO which is around a half inch shorter due to throwing the belt a few times after replacing my tensioner.and no more belt throwing.
do you guys think this could be the reason my car will heat up easy on a hot day?
