To preface this, I do not like leaving negative reviews, especially for small businesses that support the automotive community. But with that said, these radiators have some major flaws that need to be addressed and are not worth the hassle for how expensive they are.
Short backstory, I had my OEM radiator upper outlet crack/split (common issue) and ordered a Cold Case replacement. Shipping time was normal, but the packaging was pretty insufficient for a ~$400 radiator. Very little padding to protect it.
It did arrive safely, but I immediately noticed it had a dent in the top of the polished aluminum. The box was not damaged and the styrofoam protecting it was in tact. It was polished over, so clearly a manufactuing defect. No big deal, Cold Case emailed me back about a week later telling me they were filing a UPS damage claim. I'm not sure why when it clearly wasn't a shipping issue, but that was their decision.
I needed to get my car done ASAP, so I opted to just deal with the dent and get my car drive-able again. That's when a plethora of issues came about. Here's what I found:
-The radiator cap threads are not correctly machined, and cut plastic threads that dropped into the coolant system. You have to force the cap on the first 1 or 2 times you tighten it, which basically chases the plastic threads to match the aluminum radiator threads.
-The passenger transmission cooler fitting leaks. I am going to try re re-seal it again with some PTFE tape but it seems like the quick disconnect is leaking, not the threads.
-The lower coolant hose inlet hit the frame, it's not even close to fitting. I had to heat it with a torch and carefully bend it about 3/4". The black line here is where it was located originally, before bending
-The fan mounting brackets are not remotely close to holding the radiator in securely. I had to shim every single bracket with a piece of 1/4" high temp rubber.
-The filler neck is not in the OEM location
I did not have time to wait 2-3 weeks for a new radiator which is why I opted to suck it up and deal with these issues. Going back, I should've sent this back for a refund and bought a new OEM radiator. It was an absoulte headache to get this to fit.
Cold Case did respond to my concern over the lower inlet not fitting, to which they replied:
To me this isn't an excuse to sell an aftermarket "drop in" radiator. And suggesting your customers to modify/weaken a structural member on your vehicle is absurd.With some G8s, modifications must still be necessary to the frame.
There is really no rhyme or reason. Some fit perfect and some hit the frame.
Buy these at your own risk.
