CSF radiator leak.

[rascole]

My CSF high performance started to leak a small amount a few months ago. I took it to a local radiator shop to see if it would be a simple repair but they said it is leaking below the top tank and would require cutting off the top to get to the leaks. So it's scrap aluminum now. CSF will not warranty it because I bought it from Amazon, Amazon will not replace it because they no longer sell it under Prime. They did however refund me the total amount I paid. At this point I think I may go back to ACDelco replacement.

I purchased my CSF in 2017 from Redline360. It started leaking this January. I contacted Redline and CSF and CSF sent me a new radiator. I was very pleased with their customer service. I have CSF owner's email if you want it.

I have a griffin radiator, been in my truck since jan 2016. I havent done many miles on it due to lots of downtime on my truck but Id tell you it cooled great. When temps are below 80* and ac is off the rad drops ECT to t-stat opening temps. When I was running without a t-stat that was 160* on a 6.2L V8. Now Im running a 186 t-stat and my temp on the scanner is flat 185*. I got my fans set to start at 200* so they barely run in the winter now.

If I was gona get it again today, Id let them know I have a body lift and ask them to fabricate a 2" taller radiator since I got more clearance now below the radiator that can get extra airflow (I have a 2" body lift)

We have had 3 csf radiators leak all with less than 5k miles on them and all from recent batches (within the last 18 months ordered) I heard the argument that they had a bad batch years ago but it's still a problem.

I still don't fully understand why everyone seems to think they need to switch away from the GM radiator. I think I've had really good mileage out of them, and though I can't quite any actual comparative failure rates, they seem to be better than any aftermarket alternative based on what I see on the forum.

The reason I bought the CSF was because it is a little larger with more cooling capacity and the transmission cooler is twice OEM (no proof, just what they said on the phone).
