Radiator shot on '08 Grand Cherokee Laredo

Radiator failed on my Jeep and another jeep owner told me plastic was used in the manufacture of those radiators. He told me they fail quite a bit. Great high dollar repair built into this model. Can anyone offer me info on this problem

 

I don't think your radiator was designed to last as long as it did. Replacements are easy to find, just get one without plastic. The best thing you can do is change the fluid every two years or so with a flush out.

 

DIY repair will bring that expense down. Generally if you can remove one you can install one. Most oem-style replacement radiators consist of aluminum+plastic tanks. I've replaced a few radiators and it's probably the best time to consider replacing hoses, coolant, thermostat, etc. Rock Auto or local stores range from $90-190. Now if you want high-end radiators you might get some "metal" ones. Regular maintenance on the coolant will help radiators last longer whether plastic or metal.
