Engine coolant temperature may rise due to reasons such as a non-functioning cooling fan, insufficient coolant, radiator blockage, water pump failure, or cylinder erosion. An engine is a machine that converts other forms of energy into mechanical energy, first developed in the UK. It can refer to either a power-generating device or the entire machine including the power unit (e.g., gasoline engine). Types of engines include internal combustion engines (gasoline engines), external combustion engines (Stirling engines), and electric motors. An internal combustion engine is a power machine that converts thermal energy released from fuel combustion inside the engine directly into mechanical energy. An external combustion engine burns fuel outside the engine, invented in 1816 by Scottish engineer Stirling, hence also known as the Stirling engine. An electric motor is a device that converts electrical energy into mechanical energy.

The issue of high water temperature is something I've encountered while driving, often due to a malfunctioning cooling system. For example, insufficient coolant, or it becoming dirty and clogging the radiator pipes; otherwise, the water pump might fail to rotate, preventing fluid circulation; the thermostat could get stuck and not open or close properly; the fan might break down and stop spinning, leading to poor heat dissipation; sometimes there's a coolant leak or air bubbles in the radiator; or the engine is overloaded, such as when carrying heavy loads up a long slope. These situations can easily cause the temperature to skyrocket. It's important to regularly check the fluid level, clean the radiator, and test the fan's response to prevent this. Neglecting it could lead to engine cylinder scuffing, which is costly to repair. It's best to stop and address the problem as soon as it's noticed.
