As the original poster, I've been very proud of this thread and all the sharing that has taken place within it. Everyone who has contributed to it spent lots of time researching and learning what they shared. We all spent lots of money on the things that did not work before posting what did, we made lots of mistakes and tried to inform others so they would not have to make the same ones. For instance, the kind of advice Dave Mikels' has offered up in this thread is the result of YEARS of experience. That's what has always been so cool about these forums. Thank you to everyone who has freely contributed what you have learned in this thread.

Well put.

I'm putting all this information into direct use just over the past few days as my LS9 69 Camaro project has finally gotten out of paint jail.

I appreciate all the information and hard work. This has been a real highlight of a thread for the past couple of years!

Not one of us could do this sort of stuff by ourselves.

Information wants to be free. Set it free!

In a related question, I'm using the stock ZR1 intercooler (charge coolant) pump and it has a two prong connector (just 12v power and ground). The GMPP LS9 harness has three wires (which are 12V, PWM signal -- J3-42 lt. blue/white, and ground)

The stock ZR1 runs without a PWM-controlled intercooler pump, and the GMPP LS9 harness has a PWM connector for the coolant pump. Why are ZR1 LS9 and the GMPP crate LS9 wired differently in this case?

Any insight or help is much appreciated!

Anyone have any creative ideas how to mount this thing?

For others looking to mount the Corvette C6 fan on an aluminum radiator. I found that C&R Racing makes a OEM style aluminum radiator for Corvettes. I contacted them & was able to purchase the little mount tabs from them.

Scot,

Good stuff. So you ordered 2 of each? I gather each one of the part number is specific to the 4 corners...right?

I ordered 2 of the 0.55" tall with mounting hole & two of the 0.55" tall without mounting hole. Going off of the diagram they sent me, opposite diagonal corners are the same part.

Awesome. Just called them and ordered some. Surely I can cobble something together using the brackets and some other pieces.

My little clips showed up today, looks like they have been cut with a waterjet. Fan should be here soon as well as the radiator. Then can have them welded on.

Funny...mine showed up today as well. I am sure they are wondering what the heck is going on. C&R probably didn't sell this many all of last year...LOL
