• Durable Construction: Manufactured from high-quality aluminum alloy, nylon, rubber, and brass for long-lasting reliability.

3. Setup

Before beginning any testing or refilling procedures, ensure the vehicle's engine is cool and not under pressure. Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.

1. Prepare the Work Area: Ensure a clean, well-lit, and stable environment for working on the vehicle's cooling system.
2. Identify Radiator Cap Type: Determine the correct adapter from the kit that matches the vehicle's radiator or expansion tank cap. The adapters are color-coded and have molded size markings for easy selection.
3. Inspect Components: Before each use, inspect all hoses, O-rings, and adapters for any signs of wear, cracks, or damage. Replace any compromised parts to ensure proper sealing and accurate readings.
4. Connect Air Intake Joint (if applicable): If using an external air source for the vacuum purge and refill tool, connect the appropriate EU or US air intake joint.

4. Operating Instructions

4.1 Coolant Pressure Testing (Leak Detection):

1. Remove Radiator Cap: Carefully remove the vehicle's radiator or expansion tank cap once the engine is cool.
2. Select Adapter: Choose the correct adapter from the kit that fits the radiator neck or expansion tank opening.
3. Attach Pressure Pump: Securely attach the manual vacuum pump with the pressure gauge to the selected adapter.
4. Pump to Pressure: Slowly pump the hand pump until the pressure gauge reaches the recommended pressure for the vehicle's cooling system (refer to the vehicle's service manual or radiator cap for specifications). Do not exceed the maximum recommended pressure.
5. Monitor Pressure: Observe the pressure gauge for at least 5-10 minutes. A drop in pressure indicates a leak in the system.
6. Locate Leak: Visually inspect all cooling system components (hoses, radiator, heater core, water pump, connections) for signs of coolant leakage.
7. Release Pressure: Once testing is complete, carefully release the pressure by pressing the pressure relief valve on the pump.
8. Remove Tool: Detach the pressure pump and adapter from the vehicle.

4.2 Coolant Vacuum Purge & Refill:

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

1. Drain Old Coolant: Ensure the cooling system is completely drained of old coolant.
2. Attach Vacuum Purge Tool: Select the appropriate adapter and securely attach the vacuum purge and refill tool to the radiator neck or expansion tank.
3. Connect Air Source: Connect an air compressor (not included) to the air intake joint on the vacuum purge tool.
4. Create Vacuum: Open the air valve on the tool to create a vacuum in the cooling system. Monitor the vacuum gauge until it reaches the desired level (typically -25 to -28 inHg). Close the air valve.
5. Hold Vacuum: Allow the system to hold the vacuum for 2-5 minutes. If the vacuum drops, there is still a leak in the system that needs to be addressed before refilling.
6. Prepare Coolant: Place the filling hose into a container of pre-mixed coolant.
7. Refill System: Open the coolant valve on the vacuum purge tool. The vacuum will draw the coolant into the system. Continue until the system is full.
8. Remove Tool: Once refilling is complete, close the coolant valve, disconnect the air source, and remove the tool and adapter.
9. Top Off and Bleed: Top off the coolant level as needed and follow the vehicle manufacturer's instructions for bleeding any remaining air from the system.

5. Maintenance

Proper maintenance of your Orion Motor Tech Coolant Pressure Tester Kit will ensure its longevity and continued accuracy.

• Cleaning: After each use, wipe down all components with a clean, damp cloth to remove any coolant residue. Do not use harsh chemicals that could damage rubber or plastic parts.
• Inspection: Regularly inspect hoses for cracks or kinks, O-rings for wear or deformation, and gauges for damage. Replace any worn or damaged parts immediately.
• Storage: Store all components neatly in the custom-molded carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Lubrication: Periodically apply a small amount of silicone grease to O-rings to maintain their sealing properties and prevent drying out.
