Well, I pulled the rad being as it was draining fluid out the middle. It's nearly all made of rust, held together with a bit of corrosion, and has already been repaired by A-1 radiator according to a little tag on the top.
Glad I changed fluid in November with some nice new 70/30 Prestone, which is now all over the driveway.
I was planning on changing the rad this summer, along with a few other front of the engine bits, but looks like my schedule has been advanced to make sure I really have no money after Christmas.
