Concerns: Coolant distributor for high-voltage system

Symptom: After repairing the vehicle, the cooling system cannot be fully vented and refilled.

Cause: It is possible that a high-voltage coolant system distributor was installed in the vehicle that does not reach the vacuum values for venting and filling the cooling system.

Remedial Action: Check and replace high-voltage coolant distributor if necessary.
