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.

 

I had the same issue!! I wound up going to ford and getting one. OEM ftw!

 

It is a valve that allows hot coolant to flow through the heater core which in return gives you heat. I'd get one from the dealer, usually aftermarket parts are a hit or miss. Some last, some don't.

 

Thanks for the reply. I'm gonna go to the dealer or buy OEM online. OEM ftw always!!

 

Thanks for the reply and shedding some insight on what this part does. I'm going OEM.

 

I have a 1998 Ranger V6.....did your control valve leak all the time or just when you had the selector in the cab turned to a certain position? Mine leaks ONLY in the Winter time when you first start the truck and put the selector in the cab to the vent/floor position. If I leave the selector in the OFF position and let the truck warm up a few minutes and then move the selector to the vent/floor position it does not leak.
