Hot Air Problem After T/stat Housing Replacement

12 June 2012 - 01:35 AM

Hi all,
couple of weeks ago I noticed that the heater in my T reg 1.25 ZETEC was blowing cold with hot selected, this returned to normal after a few miles & I thought no more of it. 24 hours later the temp gauge hit the red as the car had developed a coolant leak. Eventually traced the leak down to the thermostat housing ( part of the o ring seal locating flange had disintergrated, un seating the seal ). I changed the housing for new but when starting the engine & up to normal running temp there was no hot air at all. Bled the water system to no avail. After about an hour took it for a spin, gave it a good booting tbh & hey presto heat came through, then faded back to cold. This was yesterday, went for a run today and heat came on as normal & got nice & warm but after about 5 mins went back to cold but sporadically warmish/ hotish air kept fading in & out. Coolant level is normal, temp gauge sitting halfway as it always has done. I had a look at the heater control valve & after just touching one of the hose connections the plastic neck the pipe connects to just "broke off". Im going to change the valve but not sure if this is the cause of my in & out hot/cold air problem. Someone has suggested head gasket failure but there are no other signs of this ( over temp, mayo etc ). Anyone got any ideas? Can find plenty of threads with either constant hot or cold air but nothing like this. Thanks for reading.

Hi all, recently got a 99 plate 1.25 Fiesta Ztec. Cost me less than £500, with 7 months tax & 12 months mot ,BARGAIN!!!. It had better behave cos I have a 100 mile a day commute. Actually I quite like the car and it drives nice. Looks like a good forum. Was going to add some photos of the car (dont know why, its nothing special) but could only get a picture of the Vother to upload. Never mind.
