Looking for some help guys. I just recently replaced the stock radiator in my 05 Cts v with an Alradco all aluminum one. Very nice by the way. The problem is now my waterpump is leaking and I was wondering if anyone out there has used an aftermarket water pump and pulley with an Alradco radiator. The new radiator is much larger and the clearance to the waterpump and pulleys is significantly reduced. The clearance is maybe a 1/4 inch or less now. I was wondering if anyone has made this change and if they could suggest a preferred replacement waterpump. I know Elderbrock makes one not sure about the others. Mainly worried about the clearance with an after market pump and pulley setup. Thanks for your help. The motor is an LS6. Any info would be appreciated.
