Like GBGN1 says.
I got one too. I figured that if if its new and paired with a good fan(s) those plasitic tanks will last longer than I think. That radiator is available at Advance online for $142 and if you throw in a couple wiper blades or a washer pump or some other small stuff your cart will go over the $150 mark. Then use their current $50 off coupon code (VISA perhaps?) and wala you got one deliverd for about a hundred. Zippadee do da!
Side question for GBGN - what cooler are you running and does it have a small fan (if so which one?) Apologies to OP for hijack.
