Radiator header tank rust - filler neck replacement

[Robert Johannesen]

I don't remember who posted the problem with the radiator header tank rusting, but I followed his advice and inspected mine - cut all the urethane foam away along with several layers of rusty pipe and sure enough, I could poke a hole in the tube with my thumb nail. I removed the tank (not an easy task- bolts are rusty also) which is stainless on my '91, with a mild steel pipe welded between the filler neck and the stainless tank. I finally found a source for the stainless steel filler neck andwill replace all with stainless steel. I am going to TIG weld a stainless coupling on the tank, then screw a stainless pipe with the filler neck into the coupling. It will probably never rust again, but it can be inspected and replaced w/o taking the tank out.

If any one needs one replaced let me know - I bought 4.
