What are the causes of engine overheating alarm?

[LondynLee]

Engine overheating alarm can be caused by the following reasons: 1. Insufficient or excessive engine oil: Many drivers make the mistake of thinking more oil is better during oil changes. Excessive oil creates greater resistance for the engine, while insufficient oil affects lubrication and heat dissipation. Therefore, when changing oil, strictly follow the oil dipstick markings to avoid overfilling or underfilling. 2. Overheated coolant temperature: If the water cooling system inside the engine runs too hot and fails to promptly cool engine components and carry away heat, the heated parts will indirectly cause the engine oil temperature to rise. 3. Clogged oil cooler: If the oil cooler becomes blocked, it directly affects normal oil heat dissipation and may lead to other issues such as insufficient oil pressure.
