What Can Be Caused by Overheating Engine?
1 Answers
Excessive vehicle coolant temperature severely affects the normal operation of the engine. Common consequences include: 1. Warning alerts for high coolant temperature or engine overheating on the dashboard. 2. The engine cooling fan rotates at high speed, producing loud noise. 3. Engine knocking may occur. 4. In severe cases, it may lead to engine bearing failure, cylinder scoring, piston sintering, and engine failure to start. Below is additional information: 1. The vehicle's coolant temperature reflects the working condition of the cooling system. The engine operates best at an appropriate high temperature, which facilitates better fuel combustion and reduces gas emissions. 2. The main causes of engine overheating include insufficient coolant, cooling fan malfunction, circulation water pump failure, thermostat failure, and poor radiator cooling performance.
