The advantage of the GE-47716 Vac-N-Fill tool is that is provides a complete cooling system fill while simultaneously purging air from the system. This can save time by eliminating the need to bleed the coolant system or thermocycle the engine when performing a coolant fill. The tool can be used on a full system, partially empty system, or a completely empty system. The tool can also be used to drain or partially drain coolant from some cooling system components using the extraction hose.
Caution: In order to avoid personal injury, do not remove the cap or open the cooling system drains from a hot system. Allow the system to cool first.
Important: To prevent boiling of the coolant/water mixture in the vehicle's cooling system, do not apply vacuum to a cooling system above 49°C (120°F). The tool will not operate properly when the coolant is boiling.
• | Install an airline nipple to the Venturi Assembly. |
• | The minimum shop air pressure requirement is 90 psi (620 kPa). |
• | The shop air should have an air dryer system. |
• | The heater control should be set to the heat position. The ignition may need to be turned to the ON position with the engine off. |
Important: Always use more coolant than necessary. This will eliminate air from being drawn into the cooling system.
Important: Some overflow hoses may need to be clamped off to obtain proper vacuum level.
Important: The cooling hoses may start to collapse. This is normal due to vacuum draw.
Important: Most vehicles will only require the process to be repeated twice.
