Re: Please recommend a replacement radiator - 69 c10 i6 250

I bought a Murray aluminum radiator for an 82 C10 that I used to own. At the time it was around $130 at my local O'Reilly Auto Parts and had a lifetime warranty. It looked very much like the new car radiators with nylon tanks.

My engine was a mild 350 with a TH350 trans, but no A/C. Even though the rad was listed as being for a 250-six and 305, it worked just fine for five Texas summers. On very hot days, my Autometer gauge showed around 180-190 on the highway, and 200 or a little more around town.

Oh yeah, the truck also had a 360 degree factory-type shroud and clutch fan, which probably helped tremendously.
