MIXED Quiz 3

Why is it NOT wise to open a hot cooling system?

• Hot coolant may erupt and cause injuries

• The engine may cool down too rapidly

• The radiator could collapse

• Coolant may be lost

Spark plug removal is common during engine fault diagnosis. Which of these is NOT a reason to remove a spark plug?

• To check for fuel fouling

• To check for coolant entry to the cylinders

• To check for knocking noises

• To perform compression tests

A technician must be able to accurately account for the facts of the diagnosis and repair processes to be successful.

• True

• False

Ignition coils:

• transform low voltage from the charging/battery systems to the high energy sparks used for ignition.

• will burn you if you touch them

• have their own power source

• deliver spark into the individual cylinders

If a thermostat were stuck open:

• The vehicle would overheat

• The engine would freeze

• The water pump will not push coolant

• The vehicle will take a long time to warm up

The part depicted:

Fuel filters are used to:

• Act as a shock absorber for the pressure spikes in the fuel system.

• Mix fuel before it gets sent to the engine

• Strain unwanted particulates from the fuel before delivery to the engine

• Relieves excess pressure, which bleeds off back to the fuel tank
