Dumping coolant.

Thanks for the input fellas!

If there was an air bubble and I topped it off,the air bubble would still be in there unless I raised the bleeder valve correct? Or would it shoot itself out via the overflow hose?

Depends upon where the air is, the air pocket will remain unless the bleeder is opened or the system is put under vacuum (the prefered method). Sometimes you don't get it all out easily with the bleeder open, and you still have to pull vacuum..........

what would your theory on the source of the leak be? Had someone ask me the other day and I couldn't think of a reason...dumping 1/2 gal a trip and puddles on the floor he says.

I've seen the "drip" show up in odd places, we had a bad water pump on a 987 dripping by the drivers rear wheel. Seems the coolant got into the undertray and ran down some lines on that side. It often has a lot to do with how the car was parked (level,not level, what amount of tilt, etc.). We also had a cracked radiator leaking both in the front and near the rear of a 986; again, the coolant was running down lines and the undertrays. These things are often an "Easter Egg hunt" until you get the car up in the air with the undertrays off.......

Could it be possible that the coolant reservoir cap and/or bleeder valve needs replaced? Mine dumped a gallon of coolant once even though it was at normal operating temperature so I replaced both of those parts and haven't had an issue since.

One of the radiator fan motors went bad. It was the original.

R & R of the radiator fan and coolant system flush...$700.
