I replaced the rad on my truck. I was a little miffed that it had a slow leak at the top where the plastic tank meets the aluminum after only 120k and 8 years. However, I was pleasently surprised with how easy the replacement went. Two hours and some scuffed knuckles and the truck was back on the road again.
Oh, and I should mention, it was much cheaper to source the rad locally than from any parts place on the internet. I've noticed this more and more lately, the online sources can't compete with the locals. Good stuff.
