i have a leak

[Danny]

At what I think is the heater check valve. Its a white and black check valve looking thing with a two wire plug coming off it. It drips onto the gas pedal/my right foot. Is there a way to get just a new one of those or maybe patch it up with some sort of silicone type stuff?

Discuss.

What year is your car? Isn't there a recall for this common problem?

[Danny]

Its an 89 325I I doubt its common but I hooked up my lines at the firewall bacwards and I think they broke it.

I have an 89' as well.
I ended up bypassing it, but yea I think it was a recall though it's vague in my head.

Nope they don't sell those better buy another car. I'll buy your engine and rims though.

Lolololol @ adrian. Abby you have more info on a bypass?

Its this thing.


Its under the dash on the drivers side, just above the gas pedal.

If you're willing to make your defroster and heater useless then I can look into it for you.

edit: I'll check my car again, but I THINK you can connect the two hoses from the firewall to eachother.

Dude, that is the valve that shuts the water flow to the heater core on and off...you NEED that!

Buy a new one, get new o rings too. Be careful not to pop the fuse, it is a nasty whore to get to.

Your temperature control has the switch in it, BTW.

Okay yea it's confirmed. You can bypass it by looping them into each other(don't just clamp off the ends = pressure build up).

That's kinda what I figured. It looks like a royal waffleswaffleswaffleswaffles to fix though. Damn.

Its not that bad, but its very time consuming. Go slow because there are many items that you can bust in there causing a drain on your wallet and patience.

Do I have to take out the dash and shit?

[Gnarles]

Might as well replace the heater core while you are down there. Pull the drivers seat, makes it so much easier to get to everything.

I just looked on pelican and its listed as $204. Uhhhh anywhere cheaper?

[Gnarles]

You could take a chance on a used one. I bought mine off of eBay 2 years ago and it's still working.
