Thread: Electric Fan Help

Tweet

I have a new clutch fan but let me ask this.....I heard you can't put flex -o- lite fan blades on a clutch fan.Is this true? Is the direct drive (fan Spacer) better than a clutch? Thanks Guys for the many replies you have given me......frankie

Let me add this too!Could it be the Accel 45,000 volt ignition coil that i installed as opposed to the stock 15,000- 20,000 coil thanks, frankie

No.

Taking the thermostat out is a mistake.
You allow the coolant to go through too fast to transfer BTU's.
Better to take your thermostat and remove the center mechanism and run just the washer (as a flow restrictor)....

Also, running an electric fan as a pusher can make the engine run warmer at speed, because you are blocking a protion of the radiator off.

If you do run an electric fan, make it a big one (3000 cfm and up)..
And run it with a circuit like this (see attached pic). With a circuit like this you have triple redundancy (a/c turns it on, temp turns it on, and you can manually turn it on)...
Hope the info helps.

i took the thermostat out, the clutch fan is new, the radiator is new,the trans cooler is new, the shroud is intact.The hotter it is outside the hotter the engine temp.This is my 1st 10.5:1 460. i had 8 other low comp. 460's that ran cool.Is it normal for these engines to run a little hot?The gauge reads about 2 clock on the factory gauge on a 69 mark 3.The only thing i have not done is adjust the carb because it leaks from the jet.could this bring the temp. down if properly adjusted? I'm gonna get a Edelbrock intake and carb in the spring.Thanks for your replies.

You might try a higher flow water pump also. I put a bigger GPM pump on mine, and heat problems disapeared. Depends on your app. but is your radiator the right size? I know you said it was new, but did you downsize it? Could be an issue if you did.

Good luck with it, let us know how it turns out.

I have a new water pump but i could not get one in the HIGH FLOW.The 69 is the only year that has a revese outlet.So i had to settle for a NOS Thank You
