How do you change spark plugs in a 37 Liberty?

Answer 1

1) Remove the air filter manifold. It will clip on the air filter on one side, and there will be a ring fastener on the other.

2) For the 3 plugs on the driver side, use a 10 mm nut driver to remove the locking nut of the spark plug terminal.

3) Disconnect the harness from the plug terminal.

4) Pull out the terminal.

5) Use a socket wrench to remove the plug.

6) For the 3 plugs on the passenger side, you will need to remove the Radiator Coolant reservoir. This is fastened with 2 10mm nuts. Once removed follow steps 2 to 5 for each plug.

Note that on the Radiator it will state what the gap should be for the spark plug.

[Edit - Just finished doing it this way]

You can get to the passenger side plugs without removing the Radiator Coolant reservoir or the air filter manifold if you use a Universal and a 12" extension. You will, however, need to remove the flex conduit between the Air Filter Mainfold and the top of the intake manifold.
