Has anyone out there ever put an electircal fan in a 67-72 chevy truck. I have 73 caddy 4 core radiator and an electical fan mounted inside a 2wd shroud with no manual fan. The truck ran fine w/o a plow but with plowing yesterday she ran warmer than I would like. Should I run a pusher fan on the front of the radiator as well.
My question is should a 4 core adequatly cool the truck in extreme work condition or is my electrical fan just not keeping up. The fans out of a 90 Seville, i'm not sure of the cfm but it is approximatley 2 feet across the blades and mounted flush to the radiato.
thanks for any and all help on this not so serious of a problem as my last one with the charging system.
Is everything else working properly?? Water pump providing flow? Thermostat holding fluid in the radiator long enough for the radiator to do it's job? Antifreeze won't cool if it doesn't stay in the radiator long enough. Fan probably shouldn't be flush. All aftermarket fans I have bought have recommended a gap between the fan and the radiator. No slug or port blockage? Radiator fins are clean so air can pass through it?
