Also, you might get $35-$45 for your old radiator core (you should separate the brass/copper parts from any steel framework prior to taking it to the scrap yard.)

Tucson The PO swapped out to a single core for some reason when he changed from diesel to the 350, he probably damaged it when the motor blew, or getting it out. Either way I just went and got the 2 core Radiator form Autozone and gave 143 for it, no core charge. And disposal works out great, I can just ad it to the ancient central air unit we just had to switch out of our house this spring. it was a 39 year old Rheem 3 ton unit, lots of copper in that one..

Bigsteve, I already checked the fan clutch, it's working fine. As you can see I figured out it was the thin Radiator. Thanks though Brother, much appreciated.
