Just put a new two row radiator in my C6. Man it got tight quick between the rad and high volume water pump no room left for anything. Just enough clearance for everything to fit.
The only issues I ran into were the trans line fittings leaking,a little gray mega thread tape took care of that.
Test drive went flawlessly going to keep an eye on it for a few trips to make sure no I have no surprises. So far so good.
Looking forward to warm weather to see if cooling improves will keep everyone posted.
