[3 Adapters]

The OEMTOOLS Universal Cooling System Filler purges those problematic airlocks, checks for vacuum leaks, and then allows the technician to refill the system quickly and easily. As you probably know, air bubbles in your coolant system can cause numerous serious issues, including overheating and engine damage. USE IS SIMPLE: 1. Before beginning, the radiator must be completely drained of fluid. And the car should be engaged and the heater turned on, so that the heater coil is open and can be evacuated and refilled. 2. You need to find the right sized rubber bush for your radiator neck or coolant reservoir, and then fit the gauged cooling system adapter firmly into place. Turn the tightener on the valve clockwise until it snugly fits the radiator neck. 3. Connect venturi valve to the cooling system adapter, connect shop air to the venturi valve, and connect evacuator hose to the other side of the venture valve; make sure all valve openings are closed until the shop air is connected. 4. The hose on the other side of the venturi valve may evacuate fluid, if any is trapped in the system, so you may want to place that tube into a waste fluid pan. 5. Once the air line is attached, open the venturi valve, and the intermediate valve on the adapter assembly; Draw vacuum until the gauge reads between 50 and 60 cmHG) 6. Close the intermediate valve and venturi valve. If the vacuum drops, you have a leak in your system. If it does not, you’re ready to refill your coolant. 7. Remove the venturi valve (cooling system adapter valve should be turned off), and connect your coolant hose. Drop the other end into a large container of coolant, mixed to your preferred specifications. Open the coolant tube valve, and the coolant will flow. Use a large container so that you won’t run out and introduce air to the coolant system. 8. When the gauge reaches 0 or the coolant stops flowing, your radiator is full.
