Drive Unit Coolant Line Pressure Value in Tesla vehicles

[jamesdarthur]

Hello Tesla lovers. Good to back there after long time I have a question which is digging my mind. I want to know coolant line pressure value in tesla vehicles, Drive unit, battery pack, etc. Where can i find those informations? Is there someone who knows ?

I'm thinking ambient pressure. The system doesn't appear to be pressurized as indicated by the coolant cap when mobile came by to top it off. Probably just a low pressure pump to circulate coolant throughout the circuit. ICE vehicles are pressurized to prevent boiling at 200 degrees of operating temperature. I know my 3 series was at 2 bar and most domestics run at 1 bar of pressure.

I think Tesla has a 5PSI release on the expansion tank. I'd have to double check, but it's a lot less than an ICE.
