Didn’t fit on my 1998 Ford Ranger, so I just cut off the Sacrificial Anode and attached it to my existing cap without issue.
Drew –
Cap did not hold 16 psi. Only held 7psi and i was told it was a “non returnable item”. So I was stuck with it.
Ron P. –
I have been using these caps for years with my aluminum motor and radiator. Stops corrosion from forming in the cooling system.
Mike Selders –
Used on my street rod with aluminum radiator/steel engine block. Great protection.
