Suggestion
It is a lot easier and efficient to vacuum fill your car because the vacuum sucks all the air out for you in a single pass.

Suggestion
Seems like it always �finds its own level� regardless of how high I fill the tank.

Now that you have a new hobby: repairing/restoring a 23 year old Porsche, buy these two tools, which you will find plenty of use for: an air compressor and a vacuum fill tool for your antifreeze.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Good morning all. I recently purchased a 2000 C2 Cabriolet, my first Porsche. It came with an extensive service history at my local Porsche dealership. This included a new coolant expansion tank and new cap about 4,000 miles ago.
When I purchased the car the coolant level was at the min line. I added coolant and about a week and a half later, the coolant level shows back at the min line. There are no observable leaks and the engine oil appears free of coolant. When the car is at operating temperature the coolant is back near the max line. The bleeder valve also operates correctly.
I�ve poured through the forums about this �issue�. My question is: is this normal operation for the expansion tank? To show min when cold and max when hot? Thanks in advance.
No, not normal operation. You probably have some air in the coolant system. Read up on how to bleed air out of the system. Or, manually open the bleed valve and drive several heating and cooling cycles.
DBJoe996 is right. Not normal. Now that you have a new hobby: repairing/restoring a 23 year old Porsche, buy these two tools, which you will find plenty of use for: an air compressor and a vacuum fill tool for your antifreeze. It is a lot easier and efficient to vacuum fill your car because the vacuum sucks all the air out for you in a single pass. The tool is powered by compressed air and you will need it again when you, inevitably, replace the water pump or any of the 16 coolant hoses around the engine. The air compressor will also power your air wrench for removing wheel or engine bolts. And since you have a cab, buy one of these: 996 561 787 01 now. It's an easily broken cover for the latch that pulls the top tight. If it breaks off (and it will) you won't be able to close the top. It's $20. Cheap by Porsche standards!
This is how my car has operated since I got it in 2014� Min when cold, Max when hot. Seems like it always �finds its own level� regardless of how high I fill the tank. Once it�s at the cold �min� level, it stays there�
Similar here, mine if you fill it more than about 5mm above min will relieve a tiny amount of coolant till its happy, usually about 4 oz..
I have the extra front radiator and mine holds a tick over 6 gallons when I filled it from dry.
