The other day I pressure tested te cooling system at 18 pounds
For 2 hours. Needle didn't even flinch. So that's good
When it gets up to op temp the hose from the thermostat
To the filler cap expands and stays expanded for a while as
The car is cooling down . So pressure seems good,
Should the blue tank be moved into the engine compartment
To try and raise it up?
I've always been Porsche "
oil cooled so you see why
I am water challenged .
