99 Silverado Electric Fans
 
Looking to install electric fans in my 99 Silverado 5.3, without any computer/PCM mods. Looking for info/advice from someone who has done this and can help, please. Trying to find that right balance between not spending too much, but not buying crap either.

What fans should I get and from where?

What fan control module should I get and from where?

If you're lookin to get out cheap then the fans you'll want are the LS1 fans from 99-02 camaro I believe..they bolt right up to the stock radiator. the 05 and up style electric fans would be better, but you'd need a new radiator, fans, harness, and tune of the PCM. and any hardware store will have a switch that you could wire it up with I believe anyways

look here at my "Taurus" fan mod, I believe that your stock PCM may support fan control but not sure? " 1997 K1500 - a set on Flickr "
