I have another stock radiator back home that is in very nice shape, although it appears to have had some of that stop leak junk run through it so it will need a good cleaning too. maybe ill look into a new radiator until I can get my stock one cleaned? I forgot to mention that the truck does run cooler for a while now before it finally climbs to right in the middle of operating range. the truck seems to be boiling over even in cooler weather too and the temp gauge is right in the middle when it does this. I should also note that it does climb higher than the middle of operating range when pulling hills so I'm thinking that the temp gauge is working properly. Ill try pulling the thermostat first and seeing what what that does. Ill check for water pump function too while i do this.
