Hey all, so I drove my old man's truck into work to dump some metal, and he's blowing radiator fluid everywhere out the cap. It was a new cap when I swung the engine in last October, 7# cap. I tested it with my cap tester, and it's completely failed.
I have a 13# cap that's floating in my toolbox, I'm gonna throw that on to keep me on the road for now, but I'm finding some conflicting info about which cap is OEM size. I've found lots of threads stating BOTH are the factory correct pressure sizes....
My working theory is that a 13# cap is correct, mostly because of my latest adventure I had with my own truck, coolant Temps were hitting 230F a few times. With a 7# cap the boiling point is 233F, so a 7# would be close. 13# would be 251F
I may be wrong, but that's why I'm here askin', what do you all think?
