#7 of 8 Insufficient heat by mcdiarmid Jan 14, 2009 (6:43 am)
Hello. I have a `95 Lumina car with a 3.1, with 280 000KMs. Single zone heat and A/C. I bought it used last August. It`s used as a taxi. I`ve replaced 2 head and intake gaskets as well as a rad, heater core and pump and installed a used head! All new parts. I`ve also replaced the thermostat 3 times, 2 of the themostats are OEM. Most of this work was done before the cold weather. I just can`t get enough heat to the vents on any setting. I`ve checked the heater hoses for heat...both are hot. I`ve tried many times to get any remaining air out of the system. There is sometimes a gurgling in the heater core, but not always. I know...air. But, every couple of days I try to bleed any air out. None. Could this simply be a switch problem?? I put about 400KMs per day on this car...there shouldn`t be anymore air. Anyone had a similar problem? Ian

Replying to: punky67 (May 31, 2007 12:26 pm) one of the fans should come on after idleing for about 5-10 minutes. otherwise im sure you'd have overheating problems.
