Document Type and Number:
Japanese Patent JP7009660
Kind Code:
B2
Abstract:
A method for filling a cooling circuit of a motor vehicle with a coolant may include filling the cooling circuit with ion-free water in a water filling operation, leaving the ion-free water in the cooling circuit for a water duration of action in a water operation of action, displacing the ion-free water out of the cooling circuit via filling the cooling circuit with a passivating agent in a passivating operation, rinsing the cooling circuit with ion-free water such that the ion-free water at least dilutes the passivating agent in the cooling circuit and a liquid including at least one of the ion-free water and the passivating agent remains in the cooling circuit in a rinsing operation, displacing the liquid out of the cooling circuit via filling the cooling circuit with the coolant in a coolant filling operation, and/or fluidically sealing the cooling circuit towards an outside in a sealing operation.
