m735isIf you put the heat back on (hot side), does the gauge go back to 1/4?

It should stay about half way, maybe you have an airpocket somewhere? Have you bled the system?01-20-06 08:47 AMI did set it back on the Hot Side and the same thing happen; it goes back to 1/4 of the gauge. I did try to bleed the system by let engine run for about 30 mins, set the heat control to HEAT, and lift passanger side up so that the bleeding valve higher than normal. Then bleed it few time; each in 10min interval while the engine still run. And I did the same thing with the Driver side. Have not seen any better result yet.
