I have a 2006 Grand Prix GXP. I have replaced the steering rack, water pump, harmonic balancer, and rewired the cooling fan with new external relays and larger wire. The old relay setup through the box was damaged in the junction box.

My newest issue is the cooling fans. The driver's side fan will not come on. I checked it with a volt meter, it is getting power but will not turn on. I know I can get a direct factory replacement for the entire assembly but I was looking at replacing both fans with higher flowing fans. I live in the Phoenix area so better cooling is always good. I realize that I will have to do some cutting of the shroud and fabrication to make them fit. Are there any fans that anyone has used that have proven a good upgraded to OE?

I was also hoping to replace the OE radiator with a 3-core aluminum radiator. I cannot find anything that is a direct fit but does anyone know of a radiator, like a Champion, or something like that which can be made to fit?
