We installed an Edelbrock high-flow aluminum water pump, Cold Case aluminum radiator, and ditched the ugly clutchless flex-fan for a stock fan with heavy-duty clutch from Ames. Now it cruises at 170F and pretty much never gets above 180F in traffic during hot and humid Michigan summers. He used to have major problems with hot starting, and now all those issues are gone. Big transformation.
