Cooling problem. Radiator recommendations?
1972 Pontiac Grandville convertible 455 all original. Car only overheats when on highway above 60 mph and outside temp makes zero difference. Whether it's a 100 plus or 60 out, same result. I installed a 160 thermostat that made no difference. Has new water pump but installed by idiots so that could be the problem or just clogged radiator unable to get rid of heat?
