I just feel like bitching If you market you vehicle as "trail rated" you should not make your radiator out of plastic. .02 Guess I'm putting a radiator in the wife's Liberty.
I hate plastic things in general on cars. Specially things like radiators. I ended up replacing the plastic metal combo one on my Miata after the plastic cracked and it started spewing coolant everywhere. The all aluminum "racing" ones by are a great upgrade, and they really aren't that expensive for something so important.
Yeah, 10 year old Jeep... I think this one should last longer than I plan to keep it (I hope). That said... PSA, if you pull the housing and the thermostat stays in your block, make sure the side of the t-stat you see when you put it in the housing to put back on the block is the other side.
