Where is the drain screw on the BMW X6?
2 Answers
The drain screw on the BMW X6 is located on the passenger side, near the exhaust pipe behind the engine. Workflow for replacing BMW coolant: Draining the coolant can be done in several ways. The standard procedure is to lift the vehicle, unscrew the drain screw at the bottom, and allow the coolant to drain from this screw hole. When adding new coolant, pour approximately 3.5L of coolant directly into the BMW X1 reservoir until the fluid level reaches the MAX mark. Start the BMW and let it idle for 3-5 minutes to reach normal operating temperature, ensuring the new coolant circulates fully through the system. After turning off the engine, check the reservoir again—the fluid level will have dropped slightly. Add more coolant as needed to maintain the level between the MAX and MIN marks. Function of coolant: Coolant, or antifreeze coolant, is designed to prevent freezing. It stops the coolant from freezing in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head.
I remember when I replaced the coolant in my BMW X6, the drain plug was located at the bottom left corner of the radiator. Just open the hood and look at the front radiator, you'll find that small plastic knob—use a flashlight to spot it clearly. Make sure to wait a few hours for the engine to cool down before working, or the hot steam can cause burns. I learned that the hard way when I rushed it once and burned my hand, so don’t skip wearing gloves. Have a large basin ready to catch the old coolant since it’s toxic and shouldn’t be spilled carelessly. Once you loosen the plug, the coolant will gush out. Wait until it’s fully drained, then clean any residue. When refilling with new coolant, pour slowly to avoid air bubbles. The plug’s position is consistently at the radiator’s base across similar BMW models. If it’s your first time, check the manual or online video tutorials for guidance—it’s a 30-minute job. Overall, the plug is designed user-friendly for DIY maintenance, but always prioritize safety and double-check the location.
