I want to replace the clutch fan on my 2003 silverado 1500 Z71 with a pair of electric fans. Has anyone done this switch before? Is it easier to buy the fans from a dealer or new somewhere, or to go to a local junk yard and get some off a truck like mine? The other thing is, after removing the fan shroud on my truck, will the new electric fans just bolt in or do I need some type of a bracket or different sized radiator?
The next thing, how hard is the wiring? Do the fans need to be hooked in to a relay or have a fuse or anything? Where do I splice into for power to the fans? And does the trucks computer need to be adjusted to kick the fans on at a certain temperature? Sorry for all the questions, but just have one more. Will I need a higher output alternator to power the fans? The alternator on the truck now is a 105 amp. Will I need to go up to 145amp?
If anyone has any info on this, please fill me in on everything I need to know. If there is a previous thread on this somewhere or on a different site, feel free to post a link as I am really wanting to do this swap but I have no idea where to start. Part numbers for anything I should need are also appreciated. Thanks guys!
