With 220k miles on the original radiator, it was starting to show signs of weakness. I hope this video helps others tackle this project too although a slightly more involved install, I'd say its very doable with moderate skill.

Not all of the parts below are required to replace the radiator in particular, the Fan Clutch, Fan Blade, and Fan Shroud can be skipped.
