Radiator cap restoration (AC)

Interesting idea James. I have a car that was b. soda blasted and the metal looks wonderful/smooth. I would be interested in seeing the results with a rad cap too. I would guess favorable results.

Sam, Do it yourself! Just a little elbow grease and some patients. If you don't want to change the seal and it holds pressure you can just clean real good with GO-JO and wipe a thin coating of grease before installation. Most of these cars never run long enough to even build up 125 degrees of pressure. Its fun to do it yourself. Relaxes ones brain a little.

I would use some safest rust remover and go from there if I didn't go with the soda.

I was referred by someone on this board to a guy who does a lot of corvette stuff. I cant remember his name right now,think he was from New Mexico. He did a really good job on my cap.

Jason - u mentioned above that you use a new Stant cap for new seals, etc. Can you go thru the procedures to install the new seals. Do you have to dismantle the vintage cap to install the new seals?

Thanks (p.s. your Windex and fine steel wool did the trick!)

Sam,

Its been awhile since I have messed with a mechanical resto on one of these caps. I don't remember how I went about it but I think it involved a stant cap. There was a thread on this a year or two ago. I think it may have been Budnate who was talking about scavenging the yards for these caps and fixing them. I'm glad the windex and steel wool worked out well. I use windex for almost everything, sometimes even glass

Sorry I could not be more helpful,

Jason

Here's a before and after pic of the cap off of my 65 vette. The plating was done with a do-it yourself kit (Caswell).

what kind of plating is it??? Nice Job.
If you need to change the seal and remove the rivet
will you use the same rivet or get a new one some where???
