Is a BMW's water temperature of 120 degrees normal?
2 Answers
BMW's water temperature of 120 degrees is abnormal and too high. The optimal operating temperature for a vehicle is around 90 degrees, and the normal operating temperature ranges between 85 and 115 degrees. If the temperature remains above 120 degrees for an extended period, it indicates an abnormal water temperature, and it is advisable to have it checked at a 4S shop. Introduction: The BMW 3 Series is a new generation of sedan products from BMW Group, with a body weight of 1465 kilograms, a straight 4-cylinder gasoline engine, and dimensions of 4.734 meters, 1.811 meters, and 1.455 meters. The BMW 3 Series has once again set new standards for its class in terms of aesthetic design, engineering design, high-tech features, as well as luxury comfort and safety. The pricing of the BMW 3 Series reflects its market positioning as a high-end sports sedan and its premium product attributes. Models: On November 22, 2019, the new BMW 3 Series 320 and 330 models were fully launched! The models introduced include the 320i Sport Package, 320Li M Sport Package, 330i M Sport Night Package, and 330Li xDrive M Sport Night Package, totaling 4 models.
I've been driving BMWs for so many years, and the normal coolant temperature should be between 90 and 100 degrees Celsius—it should never reach 120 degrees. If you see the temperature gauge showing 120 degrees, that's definitely abnormal. I've encountered similar issues before—it could be due to low coolant levels, a clogged radiator, or a malfunctioning fan. This can cause the engine to overheat, and if you keep driving, it could easily damage the head gasket or pistons, leading to expensive and troublesome repairs. I recommend pulling over immediately to check the coolant level and see if you need to top it up with clean coolant. If the radiator seems fine, the fan system might be the issue—perhaps a loose wire connection or a faulty motor. Regularly changing the coolant and cleaning the radiator's air intake can prevent such problems, especially in summer when you need to pay extra attention to temperature changes. Don’t let a small issue turn into a big one—safety first. If the temperature is abnormal, get it checked at a 4S shop right away.
