Engine/Transmission (1998.5 - 2002) Electric fans and oil coolers

[Moose]

I have been toying with the idea of installing a dual electric fan set up on my 99 2500 but I have not yet been able to locate any company that makes electric fans for our trucks... . Am I just looking in the wrong places??... . I have also been considering plumbing in an oil cooler between the oil filter and the turbo... from the looks of it thanks to the threaded fittings and stainless braided line it shouldnt be hard to accomplish... But I dont know if providing cooler (and thicker) oil to the turbo will damage it or help it... Any info on either of these topics would be appreciated...

I have also been planning on adjusting my valvs and i was wondering where I could get an info sheet on how to do it... I know the specs but I am not sure on the sequences

I also have been thinking of an electric fan in front of the coolers mostly to improve AC performance when not moving. The space between the grill and the cooler isnt much and its hard to find a thin electric fan. Hopefully we will get some input here that will point us in the right direction.

Check out (http/www.hortoninc.com) EC450 and related products controls,wiring harness etc. I have tried to install an electric fan in front of my coolers but have not found one thin enough to fit, if you do please let me know.

Auctually I was planning on completly removing the stock belt driven fan and replacing it with dual electric fans between the radiator and the engine... I have run this set up on gas engines before and it worked great... Gave me a bit more power and better mileage to boot due to a reduction in drag on the engine... Theory suggests that running electric fans on a turbo diesel will also help with turbo cool down by pulling air through the intercoolor when sitting still

I tried replacing the engine-driven fan with a dual electric fan system from Flex-a-Lite on our 1996 V-10 3500. The electrics couldn't move enough air to cool the V-10/automatic in stop-and-go and low speed traffic towing our 13,500 lb 5ver in Texas summer weather.



Let's say that Joe Donnelly's dyno testing is accurate and the engine-driven fan pulls 4 BHP. The Flex-a-Lites drew 50 amps. Well, 50 amps x 12 volts = 600 watts = about 0. 8 BHP. Even if the airfoils on the electric fans are twice as efficient as the engine driven fan, that still puts its air-moving capabilities at 1. 6 BHP versus 4 BHP for the engine-driven fan. The electrics couldn't move enough air for maximum demand cooling situations on our V-10.



I paid over $400 for my education. Take advantage of it or ignore it as you wish. Your money; your call.....
