The drain screw for the Audi Q5 radiator is located on the lower hose of the radiator. Specific location: The radiator is located at the front of the engine. When opened, you can see the electric fan. Behind the electric fan is the radiator, and the drain screw is on the lower hose of the radiator. Method for adding water to the radiator: Open the radiator cap or expansion tank cap (the filling location varies by model). Start the car. If there is no water in the radiator at all, you can first add some water, then start the car, and slowly add more water until it overflows. Then tighten the cap. You can also gently press the accelerator to raise the water temperature. Wait until the cooling fan operates. When the fan stops, use a wet towel to cover the cap and slowly open it to check if the water level has reached the standard mark. If not, add more water until it reaches the correct level.

I've been driving an Audi Q5 for several years, and the radiator drain plug is located at the bottom of the radiator, usually at the lower right or left corner towards the front. This plug is made of plastic or metal, making it easy to unscrew and drain the coolant. If it's your first time doing this, don't rush—it's best to let the car sit overnight to cool the engine, or scalding hot liquid could spray out and burn you. Remember to wear thick gloves and safety goggles, and use a pan to catch the liquid to avoid splashing and corrosion on your clothes. Coolant is toxic and shouldn't be disposed of carelessly; collect it properly and take it to an auto repair shop for disposal. The location isn't hard to find—just look under the car near the edge of the radiator for a small knob. If your Q5 model is different, such as an older version, there might be a splash guard blocking it, requiring you to remove the fender liner first. The cooling system requires regular maintenance; it's recommended to replace the coolant every two to three years to prevent corrosion, and don't skimp by using low-quality fluid. Going directly to a 4S shop for replacement is more hassle-free—safety should always come first.

As someone who frequently works on car repairs, I recommend that the drain screw for the Audi Q5's coolant reservoir is located at the bottom corner of the front radiator. The exact position varies by model year, but it's generally on the lower right side. It's a plastic screw that can be easily loosened with a small wrench. Before performing the operation, ensure the car has completely cooled down for several hours to avoid burns from hot fluid. Don't take coolant disposal lightly—collect it in a bucket and avoid spilling, as environmental contamination can lead to serious issues. Once you locate the screw, loosen it to let the fluid drain. After it's fully drained, tighten the screw and carefully refill with new coolant, making sure to bleed any air bubbles. Maintaining the cooling system is crucial—Audi requires a specific coolant mixture ratio to prevent radiator clogging. The engine bay is compact, so using hand protection tools is safer for the job. Regularly check the coolant level to avoid problems, and if unsure, refer to the owner's manual diagrams for clarity.

I once encountered the drain plug location issue on an Audi Q5, positioned at the lower part of the front radiator, typically near the driver's side. Always ensure the engine is completely cooled before operation to avoid scalding from hot components. Wear protective gloves when removing the plug and use a coolant catch pan. The design is straightforward but never overlook safety – the fluid contains corrosive agents, so avoid skin contact. The plug loosens easily; after tightening, refill with fresh fluid and test for leaks. Regular cooling system maintenance is essential, and I personally recommend leaving this task to a professional repair shop for utmost reliability.
