AliC.8 Posted July 13, 2019 Report Share Posted July 13, 2019 I'm thinking of going to E.Fan, convwrtion on my 04 SS Silverado. I've been doing research on this and I find different things. Some say I need to get the truck tuned after, some say you dont. I know I need the fans themselves and the harness. I just need to know do I need to get a bigger radiator? Do I need to get the truck tuned after doing the installation? Someone, Anyone. PLEASE HELP!! Quote Link to comment Share on other sites More sharing options...
Chevyluvn Posted July 14, 2019 Report Share Posted July 14, 2019 If you don’t already have a 34” radiator you will need to get one to Run the OEM fans. If your trying to keep the E-fan system OEM you will need to get the truck tunned after taping the 2 wires into the computer. There is ways around it with an aftermarket harness.

AliC.8 Posted July 14, 2019 Author Report Share Posted July 14, 2019 I've been looking into the wiring harness frm Nelsonperformance, and the radiator frm 1aauto, the 05 34in. Would you know the price range for the tunning by any chance? Quote Link to comment Share on other sites More sharing options...
AliC.8 Posted July 14, 2019 Author Report Share Posted July 14, 2019 What will happen if I do not get it tuned? Will the fans just cut on and off when they want? Quote Link to comment Share on other sites More sharing options...
AliC.8 Posted July 14, 2019 Author Report Share Posted July 14, 2019 Also, would I need the bigger alternator?? And if so what size would be good?? Quote Link to comment Share on other sites More sharing options...
eberhama Posted July 16, 2019 Report Share Posted July 16, 2019 you wont need a bigger alternator. If you wire it in factory style to the computer, you will need it tuned to have the fan control turned in the computer. Otherwise the fans will do nothing. You could also wire it through a relay to a toggle switch, or a cheap thermostatic switch on the engine, or just wire the relay trigger wire to key on power, and they'd just run anytime the key is on.

someotherguy Posted July 16, 2019 Report Share Posted July 16, 2019 What size alternator do you already have? 145A in my truck, original. 2006 being OEM e-fan equipped. Richard Quote Link to comment Share on other sites More sharing options...
