What are the effects of no water in the radiator and a burnt smell from the engine on a car?

[EmmanuelMarie]

The hazards of no water in the car radiator are as follows: 1. Overheating may damage the thermostat and temperature sensors inside the engine, leading to abnormal engine temperature. 2. It can cause deformation and damage to the cylinder head gasket, and in severe cases, result in water-oil mixing. It may also lead to a series of issues such as cylinder head deformation. 3. It can easily cause the cylinder block to crack or the cylinder space to shrink, making the piston rings prone to getting stuck in the cylinder. If the piston seizes and causes cylinder lock-up, it can result in piston rod deformation and throttle damage. 4. During traffic jams or prolonged idling, the engine temperature gauge may show excessively high readings, the electronic fan may operate at high speed for too long, engine noise may increase, and these issues are most noticeable when using the air conditioning in hot weather.
