Lots of coolant leaked out of back right tire, stream from trunk - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The OEM tank is the only tank to use.
All other "Cheap" tanks are junk and do not last long.
If it was my car I would do a simple coolant system pressure test to confirm it is a cracked tank and not simply a fault bleeder valve, or bad cap

+1 on OEM. PO had installed a German knock off replacement and it leaked at the seam.

Are you in a hurry to fix the car ? If you are not then I suggest you start/complete the removal of the tank . After swearing/fighting/scraping of knuckles and other " fun " you will quickly tell yourself I'm not doing this again soon

. And you will order the OEM tank .

Or you can rely on the wisdom of this forum ( there is LOTS ) and just order the OEM tank upfront . On these cars the wisdom say's OEM water pumps and overflow tanks are the way to go . Good luck and keep us updated .
