Heater control valve leaking again
I bought an aftermarket heater control valve from Napa last year and not too lnong after I installed it it started leaking. I returned it and got another one and now it is leaking again. Is there something I am missing?? Should I juast get one from a different parts store? And if anyone knows what this part actually does, I would love to know. I haven't found anything clearly stated elsewhere.
