• Vacuum cooling

What part of the cooling system acts as a heat exchanger?

• Fan

• Radiator

• Thermostat

• Water jacket

The cooling system helps in:

• Increasing fuel consumption

The most common location of a thermostat in an engine is:

• Behind the radiator cap

• On top of the engine block

• Under the cylinder head gasket

• Inside the oil pan

A thermostat begins to open at its:

• Rated temperature

• Idle speed

• Maximum combustion rate

• Freezing point

A thermostat functions like:

• Spark plug

• Heat-operated valve

• Water jacket

• Pressure cap

When the engine is cold, the thermostat is:

• Open

• Closed

• Half-open

• Stuck

Which device identifies leakage due to a cracked cylinder head or gasket?

• Radiator cap

• Pressure tester

• Combustion analyzer

• Feeler gauge

Which instrument uses UV light to detect coolant leaks?
