Radiator Time - Cold Case or Mishimoto?

kevinjohn23 · January 31

I have a 2014 GMC Sierra with the 5.3. I had a CSF radiator installed just over a year ago and it's already leaking. It is out of the warranty period. I initially thought I'd just go with the Mishimoto one but as I was telling this to a friend he told me I should check out the Cold Case Radiators. I'm not finding much information on the CC one and just a little on the Mishimoto. So, my question is do any of you have the CC one installed and what has your experience been with it? Was it a direct fit as they claim. It's significantly cheaper than the Mishimoto one by around $400. I live in Vegas and tow a bit so cooling is important as well as reliability and durability from parts. Thanks in advance for your 2 cents.

I have nothing constructive to say but that's a great looking 12 year old truck.

Cold case is a great radiator. Just make sure you don’t hard mount it to the truck. Use a bushing of some sort so there is a little give for chassis flex, this is usually what cracks welds.

How long did your OEM radiator last?

Why not use another OEM one?
