pmizell: thanks for the pic...unfortunately, I have the M104, so it doesn't do me any good.
David: I'm frustrated too! This morning, I added a couple of glasses of water to get the expansion tank level to the arrow. Drove to work (about 40 minutes, highway/city combo, speeds between 30 - 70 mph). Outside temp got to about 90 this morning, and I ran the A/C at full tilt during the last half of the trip.
Engine temp got to 100 by the time I arrived to work. I opened the hood to watch the inevitable...coolant, boiling over in the expansion tank.
There IS something wrong! I just don't know what!
