Cooling Systems

Front

What is a cooling system?

Back

A cooling system is a mechanism used to remove excess heat from an engine or other machinery to maintain optimal operating temperatures.

Front

What is the function of a thermostat in a cooling system?

Back

The thermostat senses the temperature of the coolant and regulates the flow of coolant to the radiator, allowing it to enter or exit based on temperature.

Front

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

Back

The water pump circulates coolant through the engine and radiator, ensuring efficient heat transfer and temperature regulation.

Front

What is a radiator?

Back

A radiator is a heat exchanger that dissipates heat from the coolant to the air, cooling the fluid before it returns to the engine.

Front

What is the purpose of keeping tires inflated to the correct pressure?

Back

Proper tire inflation reduces rolling resistance, which can improve fuel economy and overall vehicle efficiency.

Front

What is the impact of excessive idling on fuel economy?

Back

Excessive idling wastes fuel and can decrease overall fuel economy, as the engine consumes fuel without moving the vehicle.

Front

What is the significance of avoiding heavy braking and hard accelerations?

Back

Avoiding heavy braking and hard accelerations can improve fuel economy by reducing energy waste and maintaining smoother driving conditions.

Front

How much heat is typically lost when coolant passes through the radiator?

Back

Approximately 15°F of heat is lost when the coolant passes through the radiator.

Front

What is a recovery tank in a cooling system?

Back

A recovery tank is a reservoir that collects excess coolant that expands during heating and allows it to return to the system as it cools.

Front

What is the difference between a turbocharger and a water pump?

Back

A turbocharger increases engine power by forcing more air into the combustion chamber, while a water pump circulates coolant to regulate engine temperature.
