Bringing this great thread back from the dead. Could I in theory wire this fan with the control module up using my megasquirt as a pwm output and set the duty cycle to increase based on coolant temp from a solid state relay? That's essentially what the MB module did any way correct?

I have wondered the same thing, I run an MS3X ECU

Got my fan mounted on the ECP radiator. I cut off all 4 tabs on the sides, the one in the middle on the front side, and did a little shaving of the one side to get it to mount good. I could spend some more time on it if it is too close of a fit though I won't know for a while how close it will be. A quick measurement shows the whole assembly to be 6 1/4" thick.

Got it painted...

Nice, did you use a primer or prep the aluminum surface?

I just received the identical rad. Monday. Going black also.

Thanks, Joe

Yes, I wiped down the tanks and sides. I then used a scotchbrite pad on the tanks and sides, to give them a little "scuff". I then covered the fins with some paper. I sprayed the uncovered parts self etching epoxy primer, two thin coats. After drying, used satin black, two coats on the primed areas. I then removed the paper over the fins and gave it a thin coat, just to give it a uniform color. I didn't use any special paints, heat or radiator, to paint.

Thanks, Mark...

Hey Joe, got it finished up with the fan. I think I would try the high heat paint if I would do it again. This regular stuff seems to scratch off easy. I wonder if the high heat paint would adhere better.

The whole thing has a depth close to 6". I think this is as thin as I can get it without spending major time shaving down the shroud. I hope this will give me enough clearance to fit a belt in between it and the waterpump pulley. I am also having the shaft of that shaved down plus thin headed bolts for the pulley.

I can't believe it has been 10 years since I threw a can on the hot rod. The ironic part is the hot rod has left the country but I now own a Mercedes C55 that came stock with that fan.

Thanks for the update Mark, looks like I need to do more research.

Bringing an old thread back to life. Anyone use a Holley Dominator with this setup? What was the frequency you used for the PWM?
