I want to replace the radiator cap on my 332 as it is cracked . The JD replacement is AM105793 and is around 30 bucks . Local auto parts stores I can get jobber price of 7 bucks .

In the past on a 330 I used a Murray 7616 which is a 16 psi rated cap . It seemed to work fine with no apparent issues . But I think I came across a website in the past ( maybe here ? ) that said the original cap is rated 13 psi . Anyone know if the original is 13 ?

I've been using the ACDelco PN: 10409635; 15psi cap on my 332 with no issues. I personally prefer caps with two o-rings, which this one has.
