I removed the viscous fan clutch and fan from my 85 300D before last summer and ran it with just the AC aux fan all summer. Only above 90 F in stopped traffic was the aux fan not able to keep up (coolant temp gauge would creep up to 100F) and I'd pull over and shut the engine off, let aux fan run for a few minutes to cool it off.
I have this aluminum framed 13" elec fan that looks well built and I think would keep the coolant temps in check in the hottest days of summer around here (rarely gets above 95F). Plan is to run it at full speed at first. If sufficient, than mate it to a PWM speed controller.
I am looking for ideas in how to mount this fan which is pretty heavy at 6 lbs. What material should I use? Where should the mounting points be?
Here's a pic and video of the fan
