How to add Volkswagen G12 coolant?

[LouisLee]

Method for adding Volkswagen G12 coolant: 1. Use pliers to loosen the hose clamp of the radiator outlet pipe at the lower left corner of the engine compartment; 2. Open the pressure cap and drain the old coolant from the pipe; 3. Use an air gun to blow out excess coolant from the cooling system, then rinse with distilled water and blow until no coolant remains; 4. Add new coolant through the filling port, maintaining the liquid level between MAX and MIN, then securely close the filling port cap. Volkswagen AG is an automobile manufacturing company headquartered in Wolfsburg, Germany, founded by Ferdinand Porsche. Volkswagen's brands include Audi, SEAT, Skoda, Bentley, Bugatti, Lamborghini, and Porsche.

Last time I added coolant to my wife's Volkswagen in the garage, and I gained some experience. Remember to operate only when the engine is cold, otherwise the high-temperature liquid can spray out and scald your skin. Locate the white translucent expansion tank in the engine compartment, with warning signs on the cap. Clean the dust around the cap before slowly unscrewing it, and check if the liquid level is below the MIN mark. When refilling, be sure to use the original G12 purple coolant, as mixing with other colors can cause chemical reactions and clog the pipes. Use a funnel for stability when pouring the liquid, and don't exceed the MAX line but keep it about two fingers above the MIN mark. After tightening the cap, start the engine and let it idle for five minutes to purge air bubbles from the cooling system. Turn off the engine and check the liquid level again after half an hour, topping up to the normal position if needed. Wear gloves throughout the process to avoid skin contact, as this stuff is mildly corrosive.

DIY coolant top-up is actually quite simple, with proper preparation being key. I usually park the car overnight for complete cooling, then locate the plastic reservoir marked with a thermometer symbol on the engine's right side. When unscrewing the twist-off sealed cap, you'll hear a hissing sound indicating pressure release. Using a phone flashlight to check the transparent reservoir's scale, refill is needed when the level approaches the bottom. Only use Volkswagen-approved G12 specification coolant - color variations between batches don't matter but the specification must match. Pour in three stages, gently rocking the car after each pour to ensure proper fluid distribution. Remember the final level should be half a centimeter below the MAX line, as overfilling causes overflow when the engine heats up. Start the engine and run the heater at maximum for five minutes to ensure thorough circulation. Finally, wipe any residue around the reservoir mouth with a damp cloth to prevent dust accumulation.

Three Key Points for Adding Antifreeze to Volkswagen Cars: Wait for the Engine to Cool, Identify the Correct Tank, and Use the Right Fluid. With the engine cold, open the hood and locate the transparent reservoir with min/max markings on the side. Slowly turn the black cap counterclockwise to open it; pause for two seconds upon hearing a hissing sound before fully removing it. Always use G12-spec antifreeze, ensuring the color matches—never mix different types. Pour the fluid in small increments until it reaches the midpoint between the two level marks. Start the engine and let it idle until the temperature gauge needle moves, which helps purge air bubbles from the system. Wear safety goggles throughout the process to avoid eye contact with the fluid. Before resealing, inspect the gasket for damage—it’s critical for maintaining the cooling system’s pressure balance.
