Where is the antifreeze filling location?

[MacDaniella]

The antifreeze filling location is in the radiator. Filling method: 1. First unscrew the cap on the radiator, drain all the water in the radiator, and then tighten the bolt to completely empty the water in the radiator; 2. Use a screwdriver or a suitable wrench to unscrew the small drain screw on the thermostat, add antifreeze to the radiator until water flows from the small drain screw hole on the thermostat, then tighten the small drain screw on the thermostat; 3. Continue adding antifreeze to the radiator opening until it can no longer be filled, then remove the rubber air vent tube next to the radiator cap; 4. Start the engine, generally press the accelerator to above 3000 RPM until the radiator fan starts to cool, then release the accelerator to let the engine idle, and continue adding antifreeze to the radiator opening until water flows from the air vent tube. Let the water flow for about 3 to 5 seconds, then reconnect the air vent tube, press the accelerator to above 3000 RPM again, release the accelerator, let the engine idle, and add antifreeze to the radiator opening until it can no longer be filled; 5. Tighten the radiator cap, and the filling is complete.
