The replacement procedure is the same for all spark plugs.
Please note: all work on the car – VW JETTA III (1K2) – should be done with the engine switched off.

Step 1

Open the hood.

Step 2

Use a fender protection cover to prevent damaging paintwork and plastic parts of the car.

Step 3

Detach the connector from the ignition coil.
Step 4

Clean the ignition coil bolts. Use a wire brush. Use WD-40 spray.
Step 5

Unscrew the ignition coil bolts. Use a drive socket #10. Use a ratchet wrench.
Step 6

Remove the ignition coil.
Step 7

Clean dirt, dust and debris from inside the spark plug wells.
Step 8

Unscrew the spark plugs. Use the spark plug socket #16. Use a ratchet wrench.
Step 9

Take out the spark plugs.
Step 10

Apply a thin layer of a special high temperature anti-seize lubricant to the threads of the new spark plugs.

Replacement: spark plugs – VW JETTA III (1K2). Tip from AUTODOC:
Don't tighten the plugs with excessive force. Exceeding tightening torque can damage the thread connection. Be careful when working with a spark plug wrench. Its skewing can cause damage to the threaded connection.Lower the spark plugs into the wells carefully, making sure not to damage the electrode gap.
Step 13

Install the ignition coil.
Step 14

Tighten the ignition coil bolts. Use a drive socket #10. Use a torque wrench. Tighten it to 8 Nm torque.
Step 15

Treat the ignition coil connector with electronic spray. The spray will protect the electrical contacts from corrosion, oxidation, and will reduce the contact resistance.
Step 16

Plug in the ignition coil connector.

Step 17

Run the engine for a few minutes. This is necessary in order to make sure that the component operates properly.

Step 18

Shut off the engine.

Step 19
