How to Replace Spark Plugs in a Chrysler Town & Countryby Contributor
Chrysler Town and Country spark plugs are designed to last between 60,000 and 100,000 miles. Chrysler suggests the spark plugs on Town and Country engines be inspected and cleaned every 30,000 miles. Replacing spark plug improves gas mileage and engine strain.
Disconnect the negative battery cable and let the Town and Country engine cool completely. Replacing a spark plug in a hot engine causes damage to the cylinder head.
Locate the spark plug wires, which are situated across the front and back of the engine. You may have to remove the firewall on V-6 engines to get clear access to the spark plug wires.
Grab a spark plug wire by its boot and turn it one-half turn to the right and one-half turn to the left. This releases the lock on the spark plug. Pull the wire off the spark plug and lay the wire to the side.
Insert the socket over the spark plug and turn it counter-clockwise to loosen and remove the old plug.
Spray the cylinder well with air to remove any debris.
Insert the new spark plug into the cylinder well and tighten it in place with the socket. If you are using a tapered plug, turn it one-half turn to the left to break the washer after the plug is secure. For non-tapered plugs, use a tension tester tool to determine the tension on the plug. Look on the spark plug's packaging to find the appropriate tension.
Replace the spark plug wire and turn it one-half turn in both directions to lock it in place. Repeat this process for the remaining spark plugs.
Replace the negative battery cable and firewall, if removed.
