Default Re: Radiator Cap

Below, I believe, is what came with the car and replaced with the same about 10 years ago. AC-Delco 15 psi.

Hi! You have AC Delco RC44 17psi available in Summit Racing (there are two other 17 psi caps from Griffin Radiators brand)

I don't know if it's good for our LT-5's the 15 or 16 psi caps. Service manual and technical information specifies 17 psi caps.
