I am worried my new rebuild is losing coolant. I was running 100% water, and I flushed it today and mixed it 60/40. I am hoping that maybe I was just getting localized boiling after I turn off the car, and hat was causing air in the system and coolant (water) usage. I am getting NO smoke from the tailpipe, but I did the champagne bubbles test, and there were bubbles. But, if my theory is correct, that would cause bubbles too. Any other logical explainations, why I would hear water rushing through the heater core after start up, get champagne bubbles, and be loosing coolant (coolant buzzer even comes on when I start the car, then turns off after a little pressure builds) but still no having any white smoke from the rear??? Please tell me there is an explaination for this, and my 3k mile rebuild hasn't already popped a coolant seal.

You may have air in your system that has not yet worked its way out. To fill the system properly, jack up the car slightly on the drivers front. Remove the throttle body coolant line. Subliminal message .... Install Cheap Bastard intake. Fill the AST, while watching the TB line for overflow. Allow a few moments for the AST to drain into the system. Continue to fill the AST until it stays full. Cap the AST, and fill at the filler neck. Re-connect the TB coolant line. This should purge nearly all the air out of your system.

Its also possible that you have a coolat leak. If it is leaking while the car is running, and dripping on a hot surface, you should smell it. If it is dripping to the ground(install Cheap Bastard Intake), you should see it. It's not likely that you have a bad coolant seal after such a short time.

Ok, well, after I flushed it yesterday, I refilled with 60/40 mix, and still got no smoke or sweet smell this morning on startup. However, I did hear the coolant rushing through the heater core still. I know the main radiator hoses are good, as I recently replaced them. But I did not replace the turbo coolant hoses. With NO white smoke or sweet smell from the tailpipe, is it safe to assume that it's not a bad O-ring? I can deal with any other problem, as I can fix anything myself, except a rebuild. Which I guess I could technically figure out, but don't have the time.

if you really want to know if its a bad o ring. buy a test kit at your local hardware store, it will detect any carbon/gas ect... in the coolant stream. you could also do a comp check. pull the plugs.. are they wet? just keep purping the system and see if the soudns eventually goes away.. when you refilled the coolant system did you pop off the hose that connects to the TB?
