After driving for about 20 minutes, the temperature gauge on my BMW 3-series starts to rise. How can I troubleshoot and fix this issue?
ReplyFirstly, check the coolant level in your radiator. It may be low and causing the engine to overheat. If the coolant level is fine, then check for any leaks in the radiator or hoses. Also, make sure the radiator fan is working properly. If everything seems to be in order, it could be an issue with the thermostat. It may be stuck closed, not allowing coolant to flow through the engine and causing it to overheat. You may need to replace the thermostat if this is the case.
Another common culprit of engine overheating is a malfunctioning water pump. The water pump is responsible for circulating coolant throughout the engine. If it is not working properly, it can cause the engine to overheat. You can check the water pump by inspecting the drive belt and the pump itself for any signs of damage. If needed, the water pump should be replaced.
