Cooling System Quiz

What is the primary function of the cooling system in a vehicle?

• To enhance exhaust performance

• To improve fuel efficiency

• To maintain optimal engine temperature

• To increase engine power

Which component dissipates heat from the engine coolant to the outside air?

• Water pump

• Thermostat

• Coolant reservoir

• Radiator

What is the purpose of the radiator cap?

• To circulate coolant

• To seal the cooling system and maintain pressure

• To absorb heat from the engine

• To provide heat for the vehicle's interior

What is the main function of coolant (antifreeze)?

• To lubricate engine parts

• To absorb heat and prevent freezing

• To filter engine oil

• To enhance fuel combustion

How does the thermostat regulate coolant flow?

• By adjusting the radiator fan speed

• By controlling the water pump speed

• By maintaining coolant pressure

• By opening and closing based on engine temperature

What type of engine cooling system is most commonly used in automobiles?

• Air-cooling system

• Water-cooling system

• Oil-cooling system

• Gas-cooling system

What is the role of the water pump in the cooling system?

• To absorb heat from the engine

• To circulate coolant through the engine and radiator

• To maintain pressure in the cooling system

• To dissipate heat to the outside air

What does the radiator fan do?

• Circulates coolant

• Draws air through the radiator for cooling

• Maintains coolant pressure

• Regulates engine temperature

What is the purpose of the heater core in the cooling system?

• To circulate coolant

• To provide heat for the vehicle's interior

• To maintain engine pressure

• To cool the engine

What happens if water in the cooling system does not circulate?

• It cools the engine effectively

• It can lead to localized overheating

• It enhances engine performance

• It prevents coolant from boiling
