Thanks for the info on this thread!

BTW anyone up north around Detroit area? Im moving there in 3 months for work (transfered) and since im changing coolant obviously should I do the 50/50 mix or should I be looking at another ratio since im coming from more south climate to the cold north. any advise there would be helpful!
By the time you get here it will be hot and muggy.

50/50 is what you want.

Default CSF Radiator Warrentee

Just got my replacement radiator from CSF. The one I purchased had a very small leak. It took a couple of weeks to get the replacement due to me missing an email. They requested a few photos and sent me a new one in a sealed box. They were friendly and professional.
I went to the dealer and had a new GM radiator installed so I don't need this new one. If anyone wants it PM me 350.00
It's for a 2006 hummer h3

Bring it with you when you move up to the D, by then mine might spring a leak and I'll buy it.

You know that plastic POS factory radiator is going to crack, why not drop in the CSF?

I had 1 CSF that had a leak. I took it to a local radiator shop and they did a pressure test, found the pin hole leak and fixed it for $50 (leak test and repair). Haven't had a single issue since the repair.

Overall I think the CSF is a nice radiator but they have an issue with quality consistency. 50/50 on the 2. Cools VERY well, better than the OEM plastic ones.
