Anyone ever try an electric radiator cooling fan? Our first practice is coming up and I am going to try a fan out of a lincoln mark 8 with its own battery.

I tried everything under the sun and could not keep the car cool under green flag conditions with the electric fan(s). When we went under caution I would stop at the flagstand and cool down, but the temps went back up after a couple of laps. I hope you have better luck with it than me.

Have never tried an electric fan but am going to, either one big one or 2 12in on either side of it, I do know that with the manual I ran ditilled water in the car with a bottle of Hyper-Lube and the car ran about 210 big drop fom over heating the year before with regular water and no additive.

I run an electric fan setup out of a 93 ford taurus cost me 30 bucks and never had a problem. My car is a 85 buick regal with a 400 cid chevy. I run an oil cooler with an electric fan and a stock 3 core radiator. I used the thermostat that came in the car and knocked the center out of it for a restricter The Ford fans have 2 speeds I wired it up to run on high speed. the temp never gets over 220.

Personally I love the idea, but after ruining an engine that had always ran cool I personally could not ever do that again.

i tryed the eletric fan at the start of last year on a 4 core rad nothing but problems. as soon as the gas went down the temp went up right through the roof and what a pain to cool off i switched back to the 4 blade solid and there was a big differents.

There are a bunch of old posts about this, do a search and you will find them. At the end of the day, running an electric fan set up is possible, but everything has to be perfect. If you put a tight shroud in front of the radiator it works great (under green, you don't even need the fans to be on), but late in the year, when the nose gets roughed up a little, the air won't flow right and you have trouble.

For the past 3 seasons I've started the year with the dual electrics and ended with the old 4 blade.
