What is the name of this part?
thermostat

lower hose cap
radiator cap
What happens when pressure is increased in the cooling system by using a radiator cap?
increases the boiling point of the coolant
decreases the boiling point of the coolant
keeps the boiling point constant
changes the water to antifreeze ratio in the coolant
What forces the coolant to flow throughout the engine?
air from the front of the car
water jacket
radiator fins
water pump
What is the purpose of the radiator?
remove heat from the coolant
add heat to the coolant
slow down the air through the engine compartment
keep the coolant at 195oF (91oF)
This part is vital to a car engine's operation because it ensures the coolant keeps moving through the engine block, hoses and radiator, and maintains an optimum operating temperature.
This is like a gate that remains shut until the coolant reaches a set temperature, at which point it opens and lets coolant pass. Its basic function is to allow the engine to warm more quickly.
This is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.

What is the proper ratio of ethylene glycol to water for proper freezing/boiling points of coolant?
75%/25%
35%/65%
50%/50%
90%/10%
Which cooling system component helps circulate the coolant in the system?
Radiator
Water pump
Expansion tank
Radiator cap
Which component should you never remove on a warm/hot engine
Brake fluid cap
Expansion tank cap
Radiator cap
Oil fill cap
Why does a car need a cooling system?
Because the driver is “Hot”
To prevent the engine from overheating.
To lubricate the engine
Because it’s a good idea
Reasons why a car may overheat are:
A:The thermostat stays open
B:The thermostat does not open
C:The thermostat does not open at the right time
Both A and B
Which of the following is not a function of the radiator cap
Seal Radiator
Pressurize Cooling System
Release System Pressure
Absorb System Heat
The function of a coolant reservoir is:
uses an impeller to force coolant through the engine coolant passages.
stays closed until operating temperature is reached
stores coolant
primary heat exchanger for the vehicle engine
if a radiator core (fin area) get clogged with dirt and debris, what is the immediate effect?
poor coolant-to-air heat exchange
the coolant will not flow effectively
the cylinder head will warp
the radiator will breach
