Electric radiator fan recommendations

joe huestis · 12-21-2016, 11:15 PM

Shopping for an electric cooling fan for my '78 Camaro stocker with stock size radiator. What size, cfm rating, and amperage would be sufficient for adequate cooling ? Curved or straight blades ?

Joe, I have the same car as you. I use a Flex-a-lite fan # 118. 2500 CFM.
Works good for me. I do not use a shroud, for no particular reason.
18 Amp draw, be sure to use a relay.

Terry, thanks for the reply. What combo do you run ?

Chevrolet HHR from your Chevy parts department is a nice one. It has a built in shroud. It fits my 68 Camaro like its factory but your radiator is probably wider

Joe, I run the 175/275 HP, 350 CID in "I" trim. Stick setup.
I run my car as a coupe. The Z28 is to heavy to be a natural "I".

Shaun,
I own a 2011 HHR as my daily driver. That's an idea. Hmmm...

Why is a relay needed? Just curious, I've never used a relay, just a toggle switch and an inline fuse.

It's a lot of amps to pull thru the switch. The wire can get real hot. This way the switch only triggers the relay.
