ok so i have been searching for a replacement pressure valve for my gmc radiator. my rad is good and i plan on using it im my s10 swap truck. so here it goes. first you need to get a 16 lb rad cap fo a chevy. seaond drill out the top peaned parts of the cap to release the pressure valve. third make sure the overflow tude does not protrude and catch the valve. don't forget to get a new gasket for the plug. and finally reassamble everything and good to go. well i hope. all the parts to this fix cost me a wopping five bucks. beats buying a new radiator for a few hundred for our gmc trucks as they are a little difficult to find certian parts for.
