Filling Coolant

WARNING: Coolant outlet in the high-voltage battery

Risk of short circuit or fire
- Read out the fault memory of all high-voltage systems before checking the pressure of the cooling system.
- In the event of an insulation fault, do not apply pressure to the cooling system.
- In the event of an insulation fault, have a high-voltage expert take care of the issue.

Information

Only use Genuine Porsche coolant.
Never mix coolant with other coolants.

Information

The quantity of coolant available should exceed the amount required to fill the system by about 2 litres in order to prevent air being sucked in.
An antifreeze content of -35 °C corresponds to a mixture ratio of 50:50 (coolant/water).

Before filling the system, check whether Drain and fill coolant mode is still activated in the PIWIS Tester (fault code: P1A8100) .
Make sure that the cooling system on the vehicle is closed.
Fill the NEW container with coolant.

  > 190107 BLEEDING THE COOLING SYSTEM
6. 7.6 Press Stop after bleeding the cooling circuits to complete the process.
Remove adapter with service hose for > VAS 531 011 - cooling system servicing equipment from the coolant reservoir.

Check the coolant level in the coolant reservoir and correct it if necessary.

Only check the coolant level when the coolant temperature is at least 15° Celsius .

9.1 The correct coolant level is reached when the coolant is at the lower edge -Arrow- of the filler neck -1-
