How to Replace Spark Plugs in a VW Passat

Let the engine get cool to the point that you can touch it. Disconnect the negative battery cable form the battery.

Remove the plastic dust cover from the Passat engine. Locate the spark plug wires along the sides of the engine. There are six spark plugs in the V6 engine, three on each side.

Grab the spark plug wire and turn it one-half turn to the right and then 1/2 turn to the left to unlock the wire's boot. Pull back to remove the boot.

Use the spark plug socket, wrench and extension to unscrew the old spark plug and remove it from the well.

Apply anti-seize lubricant to the threads of the new spark plug.

Screw the spark plug into the cylinder well by hand. Test the tension and adjust it to 22 ft-lbs. by tightening or loosening the plug. The wrong tension may cause damage to the engine.

Reattach the spark plug wire. Repeat Steps 1 through 7 for the remainder of the spark plugs. Place the dust cover back on the engine and screw it into place.
