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 Dan..
