4. Safety Precautions

• Always ensure the engine is completely cool before opening the radiator cap or performing any cooling system service. Hot coolant can cause severe burns.
• Wear appropriate personal protective equipment, including safety glasses and gloves.
• Do not over-pressurize the cooling system beyond the manufacturer's recommended specifications.
• Dispose of old coolant responsibly according to local regulations.

5. Operating Instructions

5.1. Cooling System Pressure Test

This procedure helps identify leaks in the radiator, heater core, hoses, and other cooling system components.

1. Prepare the Vehicle: Ensure the engine is cool. Remove the vehicle's radiator cap.
2. Select Adapter: Choose the appropriate radiator adapter from the kit that securely fits your vehicle's radiator neck. Refer to the included instruction manual for specific vehicle compatibility.
3. Attach Adapter: Securely attach the selected adapter to the radiator neck.
4. Connect Hand Pump: Connect the manual vacuum pump (with its integrated pressure gauge) to the adapter using the quick-release coupling.
5. Pressurize System: Pump the hand pump to pressurize the cooling system. Do not exceed the vehicle manufacturer's recommended pressure (typically 10-15 PSI). Observe the pressure gauge.
6. Monitor for Leaks: Allow the system to sit under pressure for several minutes. If the pressure drops, there is a leak. Visually inspect all cooling system components (radiator, hoses, connections, water pump, heater core) for signs of coolant leakage.
7. Release Pressure: After testing, press the thumb-operated relief valve on the hand pump to safely release all pressure from the system before disconnecting the tools.
8. Remove Tools: Disconnect the hand pump and remove the radiator adapter. Reinstall the vehicle's original radiator cap.

5.2. Coolant Vacuum Purge & Refill

This method ensures the cooling system is refilled without air pockets, which can cause overheating.

1. Prepare for Refill: After any repairs, ensure the cooling system is empty of old coolant.
2. Select Adapter: Choose the correct radiator adapter for your vehicle and attach it securely to the radiator neck.
3. Connect Vacuum Purge Tool: Connect the vacuum purge and refill tool to the adapter. Ensure the valve on the tool is in the "OFF" position.
4. Connect Air Supply: Attach an air compressor (not included) to the air intake joint on the vacuum purge tool.
5. Create Vacuum: Turn the air switch on the vacuum purge tool to "ON". This will draw a vacuum in the cooling system. Monitor the vacuum gauge until it reaches -20 to -25 inHg (-50 to -60 cmHg). Once the desired vacuum is reached, turn the air switch to "OFF".
6. Check for Leaks (Vacuum): Observe the vacuum gauge for 1-2 minutes. If the vacuum holds steady, the system is sealed. If the vacuum drops, there is a leak that needs to be addressed before refilling.
7. Prepare Coolant: Place the filling hose into a container of new, pre-mixed coolant. Ensure the end of the hose is submerged.
8. Refill System: Open the coolant switch connection valve on the vacuum purge tool. The vacuum in the cooling system will draw the coolant from the container into the system. The gauge will return to 0 as the system fills.
9. Complete Refill: Continue the refilling process until the system is full and the gauge reads 0. Close the coolant switch connection valve.
10. Disconnect Tools: Disconnect the air supply, remove the vacuum purge tool, and then remove the radiator adapter. Reinstall the vehicle's original radiator cap.

6. Maintenance and Storage

• Cleaning: After each use, clean all components, especially adapters and hoses, to remove any coolant residue. Use a damp cloth and mild soap if necessary. Ensure all parts are dry before storage.
• Storage: Store the kit in its custom molded carrying case. The case is designed for effortless storage and transport, keeping all components organized and protected.
• O-Rings: Periodically inspect the O-rings for wear or damage. Replace them if necessary to maintain a tight seal. The kit includes spare O-rings.

7. Troubleshooting

• Pressure/Vacuum Does Not Hold:
  • Ensure the correct adapter is used and is securely tightened onto the radiator neck.
  • Check all hose connections for tightness.
  • Inspect O-rings for damage or improper seating.
  • If connections are secure, a leak exists within the vehicle's cooling system.
• Adapter Does Not Fit:
  • Refer to the compatibility chart in the instruction manual to ensure the correct adapter number is selected for your vehicle's make and model.
  • The kit includes a universal adapter for less common radiator neck designs.
• Coolant Does Not Draw During Refill:
  • Verify that a sufficient vacuum has been established in the system (gauge reading -20 to -25 inHg).
  • Ensure the filling hose is fully submerged in the coolant container.
  • Confirm the coolant switch connection valve on the vacuum purge tool is fully open.
