1. Introduction
This manual provides detailed instructions for the safe and effective use of your CCLIFE 3-Piece Cooling System Vacuum Filler and Leak Tester. This tool is designed for quick and air-free refilling of vehicle cooling systems and for simultaneously checking system integrity for leaks. Proper use ensures optimal performance and longevity of your vehicle's cooling system.
2. Safety Information
- Always wear appropriate personal protective equipment, including safety glasses and gloves, when working on vehicle cooling systems.
- Ensure the engine is cool before attempting to open the radiator cap or work on the cooling system. Hot coolant can cause severe burns.
- Do not operate the tool with damaged components. Inspect all hoses, connections, and the gauge for wear or damage before each use.
- Keep the work area clean and well-lit.
- Dispose of old coolant responsibly according to local regulations.
- This tool is intended for professional use or by individuals with adequate mechanical knowledge.
3. Package Contents
The CCLIFE 3-Piece Cooling System Vacuum Filler and Leak Tester kit includes the following components:
- Vacuum pump with integrated pressure gauge (with rubber protection)
- Flexible hose for coolant intake
- Universal rubber adapter cone
- Quick coupling for air supply
- Storage case

4. Setup
- Ensure the vehicle engine is completely cool and the ignition is off.
- Carefully remove the radiator cap.
- Select the appropriate universal rubber adapter cone and securely insert it into the radiator filler neck. Ensure a tight seal.
- Connect the vacuum pump assembly to the adapter cone.
- Connect an air compressor (not included) to the quick coupling on the vacuum pump. Ensure the air pressure is within the recommended range (typically 90-120 PSI).

5. Operating Instructions
5.1 Creating a Vacuum
- With the air compressor connected, open the vacuum valve on the tool (refer to the 'On' position in the image).
- The vacuum pump will begin to draw air out of the cooling system. Monitor the pressure gauge; it should show a vacuum being created.
- Continue until the gauge reaches the desired vacuum level, typically around 25-28 inHg (inches of mercury), or as specified by the vehicle manufacturer.
- Once the desired vacuum is reached, close the vacuum valve (refer to the 'Off' position in the image) and disconnect the air compressor.
5.2 Checking for Leaks
- After creating the vacuum and closing the valve, observe the pressure gauge for 2-5 minutes.
- If the gauge needle remains steady, the cooling system is sealed and free of significant leaks.
- If the gauge needle drops, there is a leak in the system. Identify and repair the leak before proceeding with coolant refilling.
5.3 Refilling the Coolant
- Place the flexible hose into a container of new, pre-mixed coolant. Ensure the hose end is fully submerged.
- Slowly open the coolant intake valve on the tool. The vacuum in the cooling system will draw the coolant into the system.
- Monitor the coolant level in the container and the gauge. The gauge will gradually return to zero as the system fills.
- Once the system is full and the gauge reads zero, close the coolant intake valve.
- Remove the tool from the radiator filler neck and replace the radiator cap.
- Start the engine and allow it to reach operating temperature. Check for any remaining air bubbles and top off coolant if necessary.
6. Maintenance
- After each use, clean the tool components, especially the rubber adapter and hoses, with water to remove any coolant residue.
- Dry all components thoroughly before storing.
- Store the tool in its original case in a clean, dry place, away from direct sunlight and extreme temperatures.
- Regularly inspect hoses for cracks or wear, and connections for tightness. Replace any damaged parts immediately.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No vacuum created | Air compressor not connected or insufficient pressure; vacuum valve closed; poor seal at radiator neck. | Check air compressor connection and pressure; open vacuum valve; ensure adapter cone is tightly sealed. |
| Vacuum drops quickly | Leak in the cooling system; loose connections on the tool. | Inspect cooling system for leaks and repair; check all tool connections for tightness. |
| Coolant not filling | Coolant intake hose not submerged; coolant intake valve closed; insufficient vacuum. | Ensure hose is fully submerged; open coolant intake valve; re-establish proper vacuum. |
