Cooling fan?

esh9 · 07-25-2009, 08:22 PM

Just purchased a 1990 suburban 4x4. It has a rebuilt engine that works great. I got the original engine also. I took the serpentine off the original engine and it bolted right up to the old. I also put a thermostat in. The single belt is on correct according to the manual but the fan is pushing air through the radiator and not pulling it. Do they make a fan with left and right pitch blads?

Welcome to the forum and howdy from TEXAS. Yes they do have a fan to fit your truck I just went though the same thing your needing a Flex-Fan that's for a reverse rotation pump or a clutch type fan blade for reverse rotation. Advance auto parts has Flex-Fans cheap or look on Ebay I seen one go for $20.00 dollars shipped on there about three weeks ago.
Good luck! GMC
PS-Your better off going to Pick & Pull and buying a fan & clutch from a 93 Chevy/Burb truck that will work and it will be cheaper remember try to find the best one meaning look for one that doesn't have signs of oil around the fan clutch. Also check to see if you didn't put the fan blade on backwards im thinking that because the fan blade should work just fine.
