Can any of you post a picture of the relief valve on your GMC radiator? I have 2 radiators and I think both of them have a crack in the neck that the pressure relief valve sets in. I took my radiator to a shop to be cleaned and checked out and I was not happy with the guy. My core is clean and pressure tested, but the lower supports are in bad shape and he did not try to fix them, or call me to tell me what he found before he put it all together, he also did not touch the pressure relief valve because he did not know how it worked or repair the overflow tube coming off the valve. I want to put a valve back in but I have not found a new valve yet and the neck looks cracked. I will try to post pics but it is really alot of work for me right now-computer issues. can you braze on a radiator(brakets & the side of the neck not the core)?
