Spark Plug Maintenance Quiz

What is the first step when removing spark plugs ?

• Disconnect the fuel injector plugs

• Check the ceramic for cracking and damage

• Remove the coil pack bolts and disconnect the wiring plugs

• Set the multi meter to ohms

What should be used to check the electrode gap of the spark plugs?

• A torque wrench

• A multi meter

• A feeler gauge

• A compression tester

What is the purpose of the ignition coil as mentioned ?

• To check the resistance of the coil

• To convert the battery voltage to high voltage needed for the spark plugs

• To measure the electrode gap

• To clean the spark plugs

What are two factors of the spark plugs that should be considered?

• Color and size

• Reach and heat range

• Resistance and voltage

• Length and durability

What should the multi meter read when ensuring it is working correctly before checking the resistance of the coil?

• 0.62 ohms

• 0 ohms

• 1 ohm

• 2 ohms

How does a distributor rotor function within the ignition system?

• It stores electrical energy for the spark plugs.

• It measures the resistance of the ignition coil.

• It directs high voltage from the coil to the spark plugs in a specific firing order.

• It cleans the distributor cap from any debris.

What is the significance of the spark plug gap?

• It determines the color of the spark.

• It affects the spark's voltage requirement and the strength of the ignition.

• It measures the durability of the spark plug.

• It indicates the resistance level of the spark plug.

Why is it important to use a torque wrench when installing spark plugs?

• To ensure the spark plugs are not too loose, preventing combustion gases from escaping.

• To clean the spark plug threads more effectively.

• To measure the resistance of the spark plug.

• To avoid over-tightening and damaging the spark plug or thread.
