Hi can anyone tell me if the 1980 corvette L-82 model 5.7L V8 came with an AUX cooling fan in front of the radiator?

If so where can i buy one? Thanks for the help

Jegs has a flex fan for High rpm (they wont shoot through the hood) and they work great/ you can feel the air at the rear of the car.went to an electric fan last yr great quailty good fan but did not trust it . 3600 rpm at 17 amps . its for sale if you need a great fan.Comes with the adjustable thermostat, needs the re-lay. $100.00 for both.Still has the lifetime warranty and it is transferable thats how good the Quality is on the fanis. I also have A chrome Alternator (jegs) lifetime warranty.100 amps I dont need that one any more going back to my stock one also $100. oo one season old 300 miles on it less.Buyer pays shipping but it will be fast I work at A UPS hub.

I have a complete one to fit an '81, including the brackets.

I don't know if it's the same for the '80 models, but if you're interested, let me know.

Do you see a heavy wiring gauge connector along the passenger's side of the engine compartment? It's in the loom that also goes to the A/C compressor.

Looking at the picture below, the blue/black wires are the ones for the aux. fan. The orange/blue wires are from the fan.

Hi yes i checked this weekend and that's exactly the way mine looks as yours does in your picture. I checked the wiring harness this week with a test light and found i had power. but the fan is not working. So i bought a fan new one on eBay for the 1980 corvette for $20.00. If that fixes the problem then OK. I am doing great and problem solved .....if not I will be in touch with you because then I will just replace the whole system and be done with it........ thanks for the help!!

You do realize that aux fan is temp controlled and won't come on untill it hits nearly 230 degrees.

Hello,

yes I understand the temp control part but 230 degrees I think that is way to high at that temperature.
I thought it turns off at 175 and comes on a 195......

You can wire a relay into the circuit and have the aux fan come on when you turn on your A/C.

Haven't checked the actual switch temp but I can believe it , BUT that is 238 "AT" the aux fan sender switch. I think the question should be what is the dash board sender reading when the aux fan sender is reading 238. They are in 2 very different places in the engine.

Yes, the switch is in the head between #s 6 and 8 cylinders.

The reason for my post was just make sure there is something wrong with your fan before searching for another. You may have never triggered it or the switch is bad. I went through the same deal when tidying up the little quirks on the '81.
