Car Forum / Dodge / Dodge Trucks / September 2005Question Re Electric Fan Gen 2 Cummins
Hi Group! I have a 1999 2WD CTD and using it as a tractor for my 28 foot 8000lb 5th wheel. Getting tired of turning on the heater fan in heavy traffic or when backing up the unit to keep the transmission coolant temperature down around 200F. Does anyone in the group know of any auxillliary electric fan mods for these trucks? TIA Fred >Hi Group! > [quoted text clipped - 11 lines] > >Fred Have you considered a more agressive clutch for fan and a more agressive fan as well? The same thing that can work for a gas motor, can work for a oil burner too. I have a 2000 k3500 gas truck and it has a HD 4 core radiator, clutch and a 10 bladed fan and it is the coolest running truck I have ever had no matter what I do it never gets above 200, even idling in traffic on a hot day with A/C on while towing. Given your units age, the clucth fan could be getting a bit weak too. > Hi Group! > [quoted text clipped - 7 lines] > > Fred Horton makes an electric fan/clutch that works great. It also has a manual switch to turn it on when needed. Its very pricy and takes a few hours to install, but does a great job I am told. Do a google search on Horton fan and you will find everything you need to know about the fan.

SignatureIf at first you don't succeed, you're not cut out for skydiving >> Hi Group! >> [quoted text clipped - 17 lines] > > "if it ain't broke, fix it until it is" The Horton for Dodge is long out of production. As far as I know they didn't even bother doing one for the 24 valve engine. I sold the one I had on my '96 rather than try to make it work on my '01, didn't think it was worth it on the old truck either. Several people on the TDR have complained about them being discontinued, the story they're getting is the material for the fan itself is no longer available. I find that hard to believe. I think it's got more to do with insufficient sales. If you want to pursue it with Horton, the site is: http://www.hortoninc.com/index_en.asp You might want to see if you can find one of the transmission cooler / fans from a first generation truck and adapt that to your truck. Shamelessly stolen text follows: But, Dodge brought out a heavy duty under-bed-mounted transmission oil cooler in mid '91 to take care of converter heating in the trucks with Cummins engines. They gave me one for my '91 so I got another and hooked them in series and also an external filter. The fans came on by temperature (I installed a manual switch also). It sounded like a B-29 when the fans were running. I could actually watch the fluid temperature come down when the fans came on during a hard pull. Thanks for the input guys...really appreciate the info. 8-) Guess I'll have to start hunting around the wrecking yards to see if I can find a Gen 1 transmission cooler. 8-( Fred >>> Hi Group! >>> [quoted text clipped - 50 lines] > temperature > come down when the fans came on during a hard pull. >> Hi Group! >> [quoted text clipped - 22 lines] > >"if it ain’t broke, fix it until it is" A question it for this application because for a electric fan to develop enough power to move enough air it takes a lot of current to do it and the power to run a electric fan of a couple of HP in size does not exist in your trucks electrical system. (it would take 130 to 150 amps minimum to make a few HP on a electric fan) > A question it for this application because for a electric fan to > develop enough power to move enough air it takes a lot of current to The Horton product being discussed is/was an electric clutch, not an electric fan. Actually using just the cab heater fan and cycling coolant through the heater core helps quite a bit...tough to do that when its 80+ degrees outside and it's raining and you have all the windows down trying to get the heat out of the cab.
