Over Heating

[68blkcpe]

Has any member here have a issue with your car over heating after using a new aftermarket fan blade? When I was working on my engine bay I switched to a Flex-a-Lite fan blade and now it seems I have over heating problems.

I plan on placing my stock fan blade back on, but just wanted to know if any other members had this problem?

Thanks.

Thanks for responding restomded66. I am using the 2nd blade shown. This didn't start happening until I changed to the new should and fan blade.

Are you running a fan shroud? From what I remember you really don't save much with a flex fan. If you have room, you are better running a stock type fan with a thermal clutch. Another thing to watch out for is fan rotation, because serpentine and v-belt setups generally run in opposite directions.

i second making sure that you are using the proper rotation fan.

I've seen a lot of threads where people with aftermarket mechanical and electrical fans have trouble with overheating. I think the aftermarket units are generally cheaper and lower quality than the OEM units.

Check rotation of fan just delt with same problem
