I am trying to document my learning thru different posts on this forum to demystify cooling system in Boxster 986.
1. Engine Oil
2. Drain pipe that is open on the other end and can be found above the rear right wheel
3. Vent or Bleeder - I see there two vents coming from the radiators and from the diagram there should be another bleeder from the Engine. These are joined some where under the body and one pipe gets to the expansion tank.
4. Coolant pipe goes to Engine
5. pressure cap ? will in open on excess pressure ?
