Coolant System Refiller Kit for Automotive with 5 Adapters, Vacuum Fill and Leak Tester

The OEMTOOLS Universal Cooling System Filler is designed to address problematic airlocks, check for vacuum leaks, and enable quick and easy coolant refilling. Using this system is straightforward:

1. Begin by completely draining the radiator of fluid. Ensure the car is running, and the heater is turned on, allowing the heater coil to be evacuated and refilled.

2. Select the appropriately sized rubber bush for your radiator neck or coolant reservoir, and firmly fit the gauged cooling system adapter into place. Tighten the valve on the adapter clockwise until it snugly fits the radiator neck.

3. Connect the venturi valve to the cooling system adapter, then connect the shop air to the venturi valve. Connect the evacuator hose to the other side of the venturi valve, ensuring 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 it's recommended 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 a vacuum until the gauge reads between 50 and 60 cmHG.

6. Close the intermediate valve and venturi valve. If the vacuum drops, there is a leak in the system. If it does not, the system is ready for coolant refilling.

7. Connect your coolant hose, with the other end dropped 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 to avoid running out and introducing air to the coolant system.

8. When the gauge reaches 0 or the coolant stops flowing, the process is complete.

The Venturi Method employed by this cooling system refiller kit draws a vacuum on the entire cooling system, ensuring no air pockets are left during refilling. This eliminates trapped air, protecting your engine.

The kit enhances efficiency by rapidly purging trapped air and refilling automotive coolant. The pressure tester makes it easy to identify cooling system issues by monitoring the gauge reading while under vacuum, revealing any leaks.

The radiator coolant vacuum refill kit includes five adapters to fit most popular radiator necks and coolant reservoirs, with bushings ranging from 31 to 45 millimeters, as well as a tapered cone adapter. It operates at the standard recommended working pressure of 70-110 PSI, with the venturi valve converting everyday air compressor input into a strong vacuum force.

The kit comes with a convenient carrying case for portability and easy storage.
