Crossing my fingers on the new radiator. It has brass/copper in the descrption. Does not say aluminum anywhere. Most of the plastic ones are aluminum with plastic tanks. Will see in a week or so.

The bad radiator actually does not look bad at all looking at the top through the cap hole. There isn't any calcification on any of the holes you can see. She is plugged solid though about 3 inches from the top. Probably had a leak at sometime in it's life and they ran a sealer through it that plugged it up solid. Especially since it is in the middle where the fan is. That's why it is overheating while idling, and cools down when you get up to speed and airflow hits the entire radiator.

Head gasket was blown when I bought the truck. I fixed it then used it mostly cruizing around the forest, and the highway on cool days last year since the AC did not work. Never really drove it around town till this year recently. Probably stopped up on previous owner and caused the head gasket to blow.
