Clutch fan vs electric fan

Pasolo · #1 09-05-2005, 04:43 PM

My next project on my 98 D with the hope of improving the mpg is to remove the belt drive fan which puts tremendous load on the engine, and installing and electric fan has anyone tried this project.

My 2000 R/T has the heavy duty cooling package so it comes with both the clutch fan and electric fan. If you plan to get a electric fan, try to get one that can closely matches the diameter of your clutch fan to get the maximum cooling. Otherwise, you can by those flex fan that is belt driven but uses way less power to operate.

Thank you for your response. I am aware that I will need to match the diameter of my stock fan as closely as possible, I also think the stock shroud might have to be modified I just hope itâ€™s worth doing.

Either that or you can mount twin fans from the back or from the front if there is room. When I had my Toyota Truck, I replaced my clutch fan with an electric one. The engine started to overheat. That's when I found out that my electric fan is much smaller than my clutch fan and was not able to do a good job moving air. I think my clutch fan was a 16 inch and my electric was a 12 incher. So I went out and bought a flex fan that is clutchless. The fan blades pitch will change with the increase in rpms so it won't work the engine at higher rpm speeds. But at idle and low rpms, the fan blades pitch more to move more air. This helped my 4 banger out alot in recovering some HP, but I moved my 12 inch fan from the back to the front to assist in the cooling mainly when I use A/C. I just spliced the incoming power to the A/C compressor clutch to power a relay which will turn on/off the electric fan.

I have both types of fans. A friend of mine has the electric fans go out and his A/C didn't work well at all. My advice is to run both!

Did you have any luck finding a kit to swap out the electric for the clutch fan? I'm looking to do the same thing in my finace's 99 D. Living in Wisconsin it has a hard time warming up (it just barely gets up to temperature by the time she get's to work) and her mpg is horrible. I've looked around a little bit to find a kit for her car, but without any luck. I was reading some of the other posts and I already changed out her water pump (different issue, it was leaking) and the coolant and thermostat so I know those are all good. If anyone knows where I can get a kit, either specific or generic, I'd appreciate it.

Socaldakota.com as mentioned above sells the Dodge Viper electric fan kit to be used as an add-on for '98/'99 Ds and replacement for '00-03 Ds. Lot's-o-parts, not just drop in, but it does work. It is somewhat pricey and Socaldak has forum reportedly had issues with responsiveness. You may order it now and have to wait and recontact them for a month+ to get it. Seems like it is on back order a lot.
