Looking for a electronic fan for my 2003 silverado z71, 5.3L. No exactly sure how large my radiator is, my guess is it's a 34''.

Thnx

 

Prob a 27" if it's the stock radiator

 

I have some LS1 fans I just took off my truck and will be selling in a few days. I'm in England right now, but will be back on Monday evening and can ship them out on Tuesday morning. It does come with a relay as well... it will control the fans via a temperature probe and you can tap into the AC wire and they will turn on whenever the AC is on. The relay looks pretty ghetto, but works great. The fans are off of a 98 Corvette. I can send ya pics when I get back to the states if you want them.
Thanks,
-Kurt
