This component keeps the system at 12-16 psi and increases the boiling point of water.
What is the radiator cap.
100
Ethylene glycol and water are mixed together to create this substance.
What is antifreeze.
100
You can perform this type of inspection when looking for problems in your cooling system.
What is a visual inspection.
100
The main function of a cooling system is to remove this.
What is heat.
100
According to the PowerPoint presentation, this tool should be used to test Ethylene Glycol (green)
What is a Hydrometer.
200
This part is driven by an electric motor or belt.
What is a fan.
200
Coolant should be replaced every ___ years.
What is 2.
200
This is caused by low coolant levels, loose fan belt, bad water pump, collapsed lower hose, or rust or scale in the water jacket.
What is engine overheating.
200
Cooling systems can be of 2 types.
What are air and liquid.
200
According to the PowerPoint presentation, this tool should be used to test Propylene Glycol (Orange).
What is a Refractometer.
300
This part runs off of 120 volts to heat your engine in cold weather so that it is easier to start your engine.
What is a block heater.
300
This is the correct ratio of Antifreeze and water for vehicles.
What is 50/50.
300
A thermostat stuck open causes the engine to do this.
What is overcool.
300
When the thermostat spring tension is overcome, the thermostat is now open to allow this to happen.
What is the coolant flowing through the radiator.
300
The hose on the Hydrometer is held up when reading the freezing point for this reason.
So it doesn't leak all over the place.
400
These parts can become soft and mushy and hard and brittle.
What are hoses.
400
The coolant should be this relative temperature before removing the radiator cap.
What is cool.
400
A loose fan belt can cause a squeal and slip and this in the engine.
What is overheating.
400
The heater core performs this function.
What is brings heat to the inside of the vehicle.
400
You can measure the freezing point and this other temperature of the coolant on the other side of the Hydrometer.
What is the boiling point.
500
These are the 5 basic components of the cooling system.
What are the hoses, radiator, fan, water pump, and thermostat.
500
If the freezing point of the coolant was -20, you can add this to the coolant to bring the freezing temperature to -37.
What is concentrated coolant.
500
This faulty part can cause overheating, overcooling, vibration, and water pump damage.
What is the fan.
500
The radiator cap performs this function.
What is pressurizing the cooling system.
