Please don't get me started on aftermarket radiators and how much they suck.
For the price of an OE radiator (which isn't that much), you're guaranteed at least 10+ years of life, and over 100k of miles before you even have to think about replacing it. Anytime I read about aftermarket radiators, I always hear of issues around the 2 year mark (sometimes sooner, sometimes later).
Every single aftermarket replacement radiator out there is made of cheap, inferior plastics with very little quality control. You can get them for pretty cheap prices at your local auto part store, but you won't have the piece of mind of knowing that it's going to last you at least 10 years. And even if it comes with a lifetime warranty, do you want to change it out again after it goes bad 2 years later?
This is truly a no brainer. Don't be one of those guys who tries to save a few bucks on one of the most important components of your vehicle by going with an aftermarket radiator. Talk to any of the experts out there and they'll always recommend an OE Mopar radiator replacement.
They really aren't that expensive either, see below:

OE Mopar Radiator:

Sorry if I seem passionate about this one. It's one thing I really hate to see is people trying to cheap out on their cooling system, which is arguably one of the most important components of your vehicle in regards to maintenance.
