Fairlane heater - just a guess.....

Hey'all I am loving my fairlane, it is such a pleasure to drive - however a thought came to me....

* The two hoses that go into the firewall (heater hoses) well the one that goes from the engine was warm till about half way then it is cold....could this indicate a blockage....I also thought that it may indicate to as why the temperature is fluctuating???

If there was a restricted flow, then it would explain the temperature guage staying at half way and that the heater works only a little.......

thanx...please help

Re: Fairlane heater - just a guess.....

The vacuum operated tap (below those hoses) has probably failed. it may appear to be working on the outside but the flap inside in probably stuck half closed with the operating leaver turning freely inside it. buy a new heater tap. It's a common problem and you will need to put the car up on ramps to change the tap and be prepared to be covered with a little coolant unless you are both quick and lucky.
