How to Replace Spark Plugs in a Chrysler Sebring

by Contributor

The Chrysler Cooperation suggests that Sebring spark plugs be changed every 60,000 to 100,000 miles, depending on how the car is driven. Sebring spark plugs need to be checked and cleaned every 30,000 miles to receive the best gas mileage for the car.

Step 1

Disconnect the negative battery cable. On a Sebring convertible, disconnect the remote negative battery cable at the left strut tower. Allow the engine to cool completely.

Step 2

Locate the spark plug wires that run across the top of the engine. On a Sebring engine, the spark plug wire boots connect directly to the engine block. Grab the wires by the boot and turn them 180 degrees in either direction to unlock the spark plug. Pull up on the wires to remove them.

Step 3

Slide the spark plug socket, extension and wrench into the cylinder well. Turn the wrench to the left to unscrew and remove the spark plug. If the spark plug is hard to turn, spray penetrating spray into the well to loosen the spark plug.

Step 4

Apply a thin coat of silicon dielectric compound onto the threads of the new spark plug and on the wire boot.

Step 5

Screw the new spark plug into place manually with the socket and extension.

Step 6

Use the tension tester tool to make sure the spark plug has a tension of 20 foot pounds. Loosen or tighten the spark plug until this tension is reached.

Reattach the spark plug wires. Turn them to the left to lock the wires into place. Replace the battery cable to the battery.
