Electric Cooling Fan control setup

I have 1976 TA, 400 ci, with mild proformance upgrades.

I'm looking for advice on the best, reliable way to control my electric fan on a daily driver.

I had a shop install a flex-a-lite, with dual 13" fans, rated at 1250cfm ea. The unit was attached directly on the radiator with zip strips, and they didn't use a relay to control the fan, just an adjustable t-stat. The engine has a 160 stat. (which I hear is to low)

So I'm replacing it with a single flex-a-lite 3000 cfm fan, with a shroud. (see pic)

Here's my thought on controling the fan, install a 180 or 195 engine t-stat, use a relay with an adjustable t-stat, using a probe.

Any suggestions, recommendations?

My independent puller electric fan system has thermocouple probe in the radiator, dial thermostat, relay, fuse. My independent pusher fan system has thermocouple/switch on radiator hose, relay, fuse. I don't use any shrouds. Fans are very effective. Been running above fans about 12 years. Had one relay fail. Had one fuse go bad; fuse element broke loose.

The fans work great but I hate the noise they make when they are running.
I plan to install a quieter clutch fan some day.

Have had a couple thermocouple failures so stopped using them, I use duel fans and now have one set to run with the key using a continuous duty soleniod instead of a relay ( is a relay, just a different sort ) the same as used for a winch, about $30. The other is on a switch and only turn it on if I need it on a regular relay, that is only when I'm waiting in the staging lines at the drag stip.

I have a 1980 ta and used a 2000 winstar van fan and shroud, has dual fans and with a little timming around the hoses and corners it looks like it was made for the car, can't tell it didn't come that way from the factory.Was $40 at the wrecker.

IMHO the best way to control a single fan is the flex-a-lite 31165-VCS, I have one and it is the bomb, never had a problem and it will prolong the elec. motor life as it is a soft start unit that is temp adjustable and can be interlocked with the ignition key or a separate toggle suppling 12VDC to turn it on.

I have a shrouded Cooling Components electric fan using a 30 amp relay and an adjustable temp sensor in a port on the intake manifold with a 180 degree thermostat.

The turn on/off temp varies a little but it works well enough that I don't have to worry about it overheating.

On recent 220 mile trip in 90+ degree weather it only turned on for a few minutes at a couple of stop lights when temp reached about 195. On the interstate and driving on rural roads at 30 mph or more it stays at 180-185 degrees.

I don't see any reason for it to run full time.

I use a Moroso thermoswitch that screws into the water crossover. it starts the fan, via relay, at 170 and turns it off at 140 and I have it hard wired so that it cools the the water in the radiator even when the engine is off. Since mine is a race car, I have the electric waterpump wired to do the same, except it is wired to run any time the ignition is on.

Did you mount the Derale thread-in probe on manifold, or the block?


Thank you,

I had to get a T-stat housing with a threaded hole. No room in the intake or heads. In fact, IIRC, my AFR 195 heads to not have any threaded holes for temp sender, etc.

lol in my rigged up old suburban I used a household light switch mounted in the dash. i don't care how it looks tho. I only turned the light switch on if I was sitting in traffic and the temp gauge started to rise. Saved me some gas tho over the old steel fan with no clutch. Fan came from an old abandoned saturn and was held on by zip ties.
