I see.

I may try to just replace the heater core. It is a long job, but I got a 3day weekend to knock it out. It will be **** cold though.

whens the last time you did a coolant flush? most likely if not in the past 50k i'd probly do one, and at the same time get thermostat unless your going to DIY, then idk..try thermostat and if dont work just do a coolant flush at a service place, if anything should happen, they will be half at fault. soo.

Before you replace the heater core make sure that you are getting hot coolant to the core. I don't know about your car but one car I worked on had a valve the was stuck so when I turned the heat up the valve didn't open.

Which would most likely be the thermostat. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I have never done one. I'll get a new thermostat as well. Is there a significant difference between the prestone version and one done at an auto repair place? If there is, I will just get it done on Monday with my front end alignment, rotate and balance, and brake system flush.

I would switch out the thermostat first..

Easy and cheap enough, I may give it a shot.

Orange. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Well, when I think of thermostat I think of the valve on the motor that kicks open when the motor gets hot...

I don't think of that valve as a thermostat... My bad...

Interesting. Swapping out the thermostat wouldn't hurt. I'll go to the dealership on Friday and get one. Shouldn't be too difficult as there are only two screws.

Based on what's going on, the logical explanations are there is no coolant getting to the heater core due to a clog or a stuck thermostat. It wouldn't hurt to swap out the thermostat so I will try the easiest / cheapest first.
