What happens when the engine cooling system fails?
Exercise is a quick way to warm up.You start slowly, but as the intensity of the exercise increases, your body starts to heat up.Your heart is drawing blood rapidly, your face is turning red and you are beginning to sweat.You can fight the heat by drinking water to help you stay cool and prevent yourself from overheating.Just like you, your engine starts out cool, but as it starts moving, it starts to generate a lot of heat and, like you, needs water to keep it cool.But the water on metal engine parts is rough and can cause rust and other damage.As a result, coolant (also known as antifreeze) was introduced to help prevent freezing of engine water during the winter months, and lubricants were used to protect it.When the cooling system fails, the engine can be seriously damaged.
How does the engine cooling system work?
- Water pump - circulating coolant
- Thermostat - Regulates coolant temperature
- Radiator - Helps cool the coolant
- Radiator cap - controls the system pressure and increases the boiling point of water due to increased pressure
- Hoses - Move coolant from the engine to the radiator as necessary and back to the heating system to heat the car interior.
What causes cars to overheat?
Most overheating problems are related to some kind of barrier or fault that prevents coolant from flowing to the radiator to release heat.The problem may be due to a failure of the thermostat, radiator, fan, or pump, resulting in a loss of coolant flow and heat dissipation.
How do I know if my car's cooling system is broken?
When something is wrong with the cooling system, your first clue will be under your nose.The needle on the thermometer will begin to rise with momentum.The check engine light may go on, and if you haven't stopped and shut down the engine at this point, smoke will start escaping from under the hood.
How can overheating damage an engine?
- Cylinder head gasket damage - Overheating can damage the seal between the cylinder head and the engine.
- Broken engine block - Overheating may cause the engine block to break beyond repair or, if repairable, lead to expensive repairs.
- Burning pistons - Overheating will burn and melt the holes in the top of the piston.The pistons are difficult to reach and require disassembly of the engine to find them.
- Engine jammed - Engine is loud when the engine shuts down and exits all synergies.When this happens, replacement is usually the only solution.
How do you prevent an engine from overheating?
- Look for leaks in radiators, engine blocks, pumps, or hoses
- Check the radiator fin or cooling fan for clogging
- Check radiator cap and/or seal
- Check the water pump and the serpentine belt
