heater takes forever to get warm
In a 2002 LeSabre the hot air is lukewarm for at least an hour. It could be normal but that seems unlikely. -- Reply in group, but if emailing, add a zero and remove the last word. |

Data display shows coolant temp between 175 and 220 depending on airflow due to speed. -- Reply in group, but if emailing, add a zero and remove the last word. |

Probably the mixer door isn't working properly. |

Is the coolant nice and clean or is it cloudy and brown? Have you been changing the coolant every year? Find the coolant valve....when you turn the heat on and off, is it making a clunking noise or not? If the system is gunked up, it may be sticking, even if the core isn't clogged up yet. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The computer just assumes that the vehicle is taking longer to warm up. -- Steve W. |

Temperature should start at ambient, Start engine and temp should rapidly climb to right around 210-220 degrees and stay there. You might get a few fluctuations as the thermostat cycles as it heats up and hit's the thermostats opening temp (195) Shouldn't take much over 305 minutes from cold for the temp to stabilize. This assumes your coolant level is full. -- Steve W. |

At least it seemed that way, and the Buick is definitely GM... I don't know if that car still used a heater control valve that shut off the coolant flow to the heater core. That could also be stuck closed. But then again, his description of the temperature variation while driving does look like a thermostat. |
