AST fitment question (plastic chewd?)
ok i think my Cap is not sealing well on the AST.. due to age and the plastic getting chewd up by taking on/off the cap. has anyone else had this problem?? iam trying to fix a coolant leak ( air leak )
i pressure test the system with the mazda cap on the AST with pressure tester on the filler neck. @ 11 psi i can hear air escaping thorugh AST cap i have ALL new water/heater hoses and new caps from mazda
next question if i get a new AST why would one buy the metal AST that uses the stant ( bigger type ) rad caps? as they do not work as well?

I've never had any issue with my Stant cap...

Most either go with an aftermarket metal one or as mentioned eliminate the AST. If your still running the stock one your just asking for a cooling system failure.
