My BMW X3 has encountered issues with the engine running too hot, and I've summarized a few common causes. The radiator might be clogged—too much dust can hinder heat dissipation, especially when driving in the city. Low or leaking coolant is also a serious issue; I once checked the radiator and hoses and found cracks that needed replacement. Water pump failure is another frequent problem—it reduces fluid circulation, leading to engine overheating. The fan sometimes malfunctions, particularly in traffic jams or hot weather—if it stops spinning, the temperature can spike rapidly. Additionally, a faulty thermostat stuck in the closed position can disrupt flow regulation. In such cases, I immediately find a safe spot to stop, turn off the engine, and avoid driving further to prevent engine damage. Then, I check the coolant level and top it up if low as an emergency measure. It’s best to visit a repair shop early, such as a BMW specialist, for professional diagnosis and handling. Avoid DIY repairs to prevent worsening the issue—safety always comes first.
