Abstract:
1. A method for vacuum filling a vehicular cooling system with coolant, comprising: providing a vehicular cooling system comprising a coolant reservoir having a coolant reservoir inlet and a coolant reservoir outlet, the coolant reservoir outlet being in liquid communication with a cooling system inlet port; providing a source of coolant; providing a source of vacuum pressure; providing a fill tool, comprising an elongated hollow member configured to pass through the coolant reservoir of the vehicular cooling system, the hollow member including a distal end and a proximal end, the distal end being configured to form an airtight seal with an inlet port of the vehicular cooling system, and the proximal end being attached to the source of coolant and the source of vacuum pressure; attaching the fill tool to the vehicular cooling system inlet port by passing the elongated hollow member through the coolant reservoir inlet and coolant reservoir outlet to form an airtight seal between the distal end and the inlet port; applying a vacuum from the source of vacuum pressure to the cooling system inlet port through the fill tool; and delivering coolant from the source of coolant to the cooling system inlet port through the fill tool.
