The fastest, easiest way to know exactly when it's safe to open your radiator cap. Fits most 1955-1993 AMC, GM, Ford, Jeep, and Chrysler 4, 6, and 8 cylinder radiators. Emission Code: 5.
Works great such a tight fit you need plyers to get it on and off but that to me just insures it doesnt leak could be a better fit simply so on and off is easier but ive had this for a year now and its still holding everything in
LOVE THIS THING!!!!!!!!! MAKE SURE IT IS JUST FOR THE YEAR AND ENGINE OF THE CAR BEING USED FOR.....EVERYONE WANTS TO KNOW WHERE I GOT IT..... 5***** :)
