So search around on the net first to see the compatability of the type of radiator you want to use.
The problem is I'm wondering if anyone here has a source for an all metal radiator. You can look online and there's a lot of people with the 4.0L engine who dump the plastic/metal radiator for an all metal one. But I have yet to see where they bought the radiator. I'm just trying to see if anyone here knows where to buy one.
I don't think it's much of a question on what one will last longer. This crappy plastic one lasted < 10 years and 120k miles, it's a piece of junk.
