cool Heater Taps in E-series cars

Just replaced my heater tap in my ea falcon. $48 from repco. It was leaking small amounts of coolant and the metal pipe end was corroded beyond a joke. Also the little plastic flipper inside had come away from the metal vacume actuator so the heater tap looked like it was closed but really was always open. The A/C works alot better now and I don't get annoying condensation build up on all my air ducts under the dash when A/C is on. The bloke at repco said that probably 50% of EA-ED cars would have faulty heater taps by now and it could lead to be problems later on if not fixed. eg loss of coolant, blown head gasket or cracked head.

cheers jjj

Re: Heater Taps in E-series cars

Yeah I replaced mine a couple months ago, and while it didn't make my heater 100%, it did noticably improve it. They're a revised design now, where they're pretty much 100% plastic so they don't corrode. At least that's the Ford design anyway. I paid $28 for mine through work (a Ford dealer).

Guys, I'm having trouble with the heating in my EA, in fact there is no heat at all. I checked both the hoses after the engine had warmed up and both were cool. Me think something is blocked there and I don't think the heater valve is working either.

But was is the heater taps you are referring to and would it relate to my problem at all.

Cheers,
Steve

Re: Heater Taps in E-series cars

Check your thermostat. If both the hoses are cool then theres a problem somewhere. The bottom hose should be cooler than the top. That might explain the lack of heat in the cabin but your heater tap may be non functional as well. Perhaps a full cooling system overhaul might be a good idea?

Well, I've just had the radiator replaced so the next step is the thermostat.

When you mention bottom hose as opposed to the top, on my EA, the 2 hoses are side-by-side as they go into the firewall or am I looking in the wrong place. One of those hoses is connected to the heater tap, which I now understand, which has a green hose connected to it.

I had this hose disconnected and was getting a hissing sound within the cabin which is now fixed. But, my fans are stuck on face and do not change to demist or foot when I change them, they just stopped working a few weeks ago. Does that relate to it at all?

Cheers,
Steve

Re: Heater Taps in E-series cars

I'm sorry, I thought you were talking about the radiator hoses.

The 2 hoses for the heater core will stay cold if there isn't ewater flowing through them. This will mean there is either a blockage (highly unlikely) or the heater tap is stuffed. Take the hoses off and put a garden hose up one and see if it flows out the other one.

If the fans are suck on face there might be another problem. The heating system defaults to screen if there is a vac leak. I don't know why yours only works on face unless there is a fault with the mechinisim which controls the vacuum routing.

Ok, might give it a go tonight.

Also, when burying myself under the big tennis racket looking at these hoses I noticed some air blowing out of the firewall, I'll try and describe it. It's an outlet pipe of some sort, seems about 1.5 inches long, hard plastic. There is a cut piece under the bottom part. It is located on the firewall about 5 inches below where the air-conditioning pipes entire the firewall. With the engine running, if I put my hand in front of this it is blowing air out.

What is this for? Is it supposed to have a vaccuum hose connected to it at all? is it supposed to be blowing air?

Cheers,
Steve
