How to Replace Spark Plugs on a 2001 Aztekby Jared Curtis
The spark plugs in your 2001 Pontiac Aztec should be replaced often to maintain engine performance. Fouled spark plugs can cause damage to the engine. Poor fuel economy is one of the first symptoms of fouled spark plugs. Burnt spark plugs will eventually fail and you will be stranded. Changing the spark plugs on your 2001 Aztec is tricky. You must rotate the engine to remove and replace the rear spark plugs, but you can change them yourself with simple tools.
Replacing Front Spark Plugs
Park your Aztec and allow the engine to cool. Raise the hood of your Aztec.
Locate three spark plug wires on the front of the engine. The spark plugs are underneath these wires. Remove the wires from the spark plug by grasping the wire and pulling it towards you. Remove each wire one at a time to avoid confusion.
Remove the spark plugs by rotating them counterclockwise with a ratchet and socket.
Insert the new spark plugs into the spark plug well by turning the plug clockwise. Tighten the spark plugs down using a ratchet and socket.
Replacing Rear Spark Plugs
Locate the rear motor mount supports on the bottom side of the engine. Remove the bolts using a ratchet and socket.
Place the vehicle in neutral and confirm the parking brake is engaged.
Install the J 41131 rotation tool onto the engine using a ratchet and socket. The J 41131 rotation tool is a special tool designed to attach to the engine to allow it to be rotated. These are available at your local dealer. Attach a ratchet strap to the J 41131 rotation tool.
Lift the motor using the ratchet strap enough to reach the rear spark plugs on the engine.
Remove and replace the spark plugs in the same manner as the front spark plugs. Lower the engine back into position. Install the bolts in the motor mounts and tighten using a ratchet.
