I have a 5.3l with 60cc Patriot Heads and the ls1 fans that i have I don't think are doing the job. We're still getting a little warm under the hood sitting in traffic.

I also have a 34" Genesis Aluminum radiator, new water pump and stat.

Would the fans from a 2500 or 4x4 do the trick, and could I use the same wiring harness?

Thanks... Lisa

 

The factory truck fans will work. i think that the plugs might be different though. Otherwise you could use the same harness.
How are you liking that rad? Mine is still working really well.

 

Radiator is a great buy, and works like a charm.

 

i have the genisis three core all aluminum ,160 stat, and two 14" flex a litte fans..... Works like a charm.... And you mean getting a little to hot under the hood what temps are u referring to?

 

Engine temp. I have an Aeroforce gauge and I have it set for the engine and trans. Trans is normally below 20-30 degrees from engine.

Last week I was sitting in traffic on the highway, and I hit 230 on the engine. That's a little high for me, and it was only in the high 70's that day.

And I have the 50/50 Dex-cool as well.

Sounds like one of the fans isnt working to me...

 

383.. I'm thinking that too...

Just can't decide to do with the dual fans or one big one.....

 

I would just go with factory duals. You dont need to have the one running full blast all the time when the A/C is on.

 

Brent.. thanks for making me think of that...

I have the harness to run the two.. why not use it.

 

So what are the CFMs on the stock fans?
