[QUOTE="BuickGirlFromMars, post: 377306, member: 48664"] Your factory thermostat is NOT 210 degrees, that is insanely hot. 190 or 195 was the factory hot thermostat, 180 was a cold factory thermostat. 180 is too cold for the winter unless your cooling system doesnt work right. Are you losing coolant? You have original dexcool at 80k miles, your DEXCOOL has spent many years sitting and breaking down. Its not meant to go that long. Flush it out. Your blend doors dont make your engine run cold, you need to confirm your engine is at the proper temp before worrying about your blend doors. Flush your coolant, makes sure your heater core is flushed well in this, and put nice fresh new DEXCOOL or green(one or the other, not both, full flushed). Then get the air out. You have a bleeder valve on your thermostat housing and various ways to bleed air. Jacking up the front of the car so the radiator cap is the top of the cooling system is a good way. Run the car with cap off till its warm for thermostat to open, once its open youll see coolant level drop. Keep it full. Burb the hoses, etc. A no spill funnel makes this easy. Then cap it and make sure its operating properly. Air pockets in cooling system can make your coolant read cold if the pocket is next to the coolant sensor. Once your coolant is good, report back with any issues like interior heating [/QUOTE]
