I haven't paid the list much attention and saw a bazillion posts for this guy who thought he toasted his engine changing the coolant. Just so happens I changed mine last week. The PO hadn't ever changed the t-stat and the shops which had done his maintenance obviously didn't know of the block drain judging from the difficulty in removing and the sludge on the inside. The t-stat had broken in half at the welds and I was getting little to no heatup for the past week.

Hopefully, at the next coolant change, coolant will actually flow out of the now clean drain nipple before it comes all the way out of the threads! Anyway, I had the same experience with the burp. Squeezed the hoses, etc, and then drove it for a few miles. No heat for a good while, I figured the system had an air pocket. Finally got some heat, got back to the house, and saw the level had dropped out of the exp tank! Topped it off again, and I've still had to top it off twice since then as the fluid fills the nooks and crannies. I'm probably leaking a little out the WP, but I was thinking I was burning coolant out the exhaust with all of the losses I had.

Now that the level has steadied out and I've read this other guy's problem, I'm feeling a lot better about the integrity of my system. Thanks, list!!!!!
