water valve

[C928BRAN]

there is a water valve inside of my a/c box, that is leaking. how hard is it to remove this valve, and what is the purpose of this valve?

thanks, craig

sounds like mabey your heater core is leaking.

I think I know the valve you're referring to. Mine leaked at one point too.
I think it bypasses the second half of the heater core to adjust the heat available.
It would take removing the whole heater box to get at it.

Thats what i was afraid of. i dont know why it needs it, if you have the heater control valve on the firewall. i am going to try to atempt to remove it, i wish i had tried to fix it when i had it out, but owell. you never think about these things sometimes.

There is a bypass valve on the core. And yes they are avail.
Complete removal and teardwon of the a/c - heater box is required to change it

FYI, have the core ck'd while it's apart just in case

I believe they cost about $70 from Old Aire Systems.

Yes, you will have to take apart the whole A/C box. I did mine a couple of years ago- It is not a hard job but a long one and a pain: remove your center console, seat (It really makes it so much easier). It took me about 2 weeks of working on it a couple of hours every other day. As long as you are "in there" you might as well replace everything you can; you really only want to repair this once.
