Hi all, i picked up a cheap 944 convertible a couple of weeks ago, it had just had a new head gaskit, belts etc, but it runs cool, i have fitted a new thermostat (80c), and it still barely gets past quarter way on the temp gauge, so i guess there is a air lock in the system. is this a common fault and is there a easy fix. thanks |

i believe it is. the best i get from the heater is nearly warm air. and thats if the car is standing. if i turn the fan on, the air soon blows cold. |

A normal thermostat is 88c AFAIK. Does your radiator fan run a lot? If only we could swap your over cooling for my over heating, we might have two good cars! |

Mine is like this although I think my heater is working fine. I was looking to replace the temp sensor first. |

Hello and welcome, have you checked that one or both of the fans aren't running constantly ? |

HI, just spent ages flushing clean water through the system, now it runs even colder! new stat is 80c, it seems some cars run an 87c stat so i have orderd one. fans come on and go off correctly it seems! Head gaskit is fine, what temp stats are other members using? regards |

Is it possible (input from other's needed here) that your temperature gauge is just wrong? Temperature sender maybe? What's wrong with it running cool? If the temperature gauge does increase a bit, and the fans operate, it's clearly reaching 80-90c, which I though was ideal. |

maybe i have been wrong when i say running cool, its the heater running cool but the temperature gauge never gets to the midway position, i guess i should replace the temp sender and see if that alters the needle position, but that still wont give me warm air. regards |

Oh in that case, how about the heater valve and the infamous disconnected cable? |

I had not thought of that, i'm guessing one end is at the back of the heater control panel and the other at a valve some where, but where? thanks |

The valve is on a small hose near the firewall in the engine bay. The cable is (apparently) accessed from the passenger footwell. |
