    Years ago, I was told that by changing the stock fan to a “Flex Fan” would provide better cooling. So I did change my stock fan to a Flex-Fan and now I want to change it back to a stock configuration. Here is the problem, I’ve moved a few times and I’ve lost the stock fan, clutch and bolts. I would like to know what aftermarket set up can I use ? I spend a lot of time in the hot desert and I need the best stock cooling set up.


    thanks

    Look for a 70s 350 in a junkyard. My motor I rebuilt came with a 7 blade clutch fan. I run that one right now and it cools pretty darn good.

    Don't get a fan from a 70's truck. It will blow air forward in your truck. /forums/images/graemlins/eek.gif Your '90 should have a serpentine belt drive, which drives the water pump (and fan) backwards from earlier engines. So you will need to find a fan and clutch that came from a truck with the serpentine drive.

    oh you are very right, sorry I didn't notice the 1990. DON'T USE a 70s fan like he said. Just junkyard for a factory serpentine chevy TBI truck fan.
