If the temp gauge reads normal and the engine is not overheating, the thermostat is doing its job. The thermostat maintains the coolant temp by opening and closing allowing the coolant to flow or not to flow. When it is closed the coolant doesn't circulate.
A radiator had 2 major mode of heat tansfer. One is radiation where the energy is emitted in the form of infrared radiation to the surrounding. Other is convection since the hot surface cause air to expand and induce wind motion and cause rapid cooling.
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
A hot-water radiator heats a room by transferring heat from the hot water flowing through the radiator to the metal surface of the radiator. The metal then radiates this heat into the surrounding air in the room through a combination of conduction and convection. As the air near the radiator heats up, it rises, creating a natural circulation of warm air in the room.
A radiator can leak water due to a cracked or corroded radiator, loose connections, a faulty radiator cap, or overheating causing pressure buildup. It is important to identify the cause of the leak and address it promptly to avoid damaging the engine or causing overheating.
The hot water that enters the radiator rises to the top as it is lighter and less dense than the cooler water at the bottom. This creates a temperature difference between the top and bottom of the radiator. Heat is transferred from the hot water to the radiator fins, which in turn heats the surrounding air.
Radiator cap
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
I would suspect a clog in the radiator.
radiator cap
it is possible for heat from combustion to cause an engine to overheat quickly depending on where the gasket is blown, but i would look for a lack of coolant circulation first. if your coolant is not getting out of the motor and into the radiator it will overheat very quickly.
A leaking radiator hose would NOT cause this to happen, you have 2 problems with this vehicle.
Check valve in radiator cap malfunction, replace radiator cap.
They get old and become weak.
YES
Because it would cause the universe to explode
poor water circulation
