How to Replace Spark Plugs in a Jeep Patriotby Russell Wood
The spark plugs on a Jeep Patriot are unusual from other vehicles as they are supposed to be changed every 30,000 miles. The factory plugs have a copper tip, which conducts electricity very well, but is so soft that it wears quickly. Fortunately, changing out the plugs isn't a complicated task since everything is easily accessible. In this case, the project vehicle is a 2006 Jeep Patriot, but the process is similar for other years as well.
Pop the hood and locate the spark plug wires at the base of the cylinder head, right by the exhaust manifold on the engine. Grab the closest wire to you and pull it off of the plug using a twisting and pulling motion.
Install he spark plug socket onto the ratchet and extension, then unbolt the spark plug from the cylinder head. Pull it out and discard it.
Gap the replacement spark plug using the spark plug gapping tool. Slide the tool between the electrode at the end of the plug and the tip until the gap between the two matches the specifications listed by Jeep in the Patriot's handbook that comes with the vehicle.
Install the replacement plug into the cylinder head, tightening it place using the 3/8-inch ratchet, extension and spark plug socket.
Repeat Steps 2 through 4 for each spark plug on the engine, working one at a time so that you don't confuse the plug wires in the process.
- Allow your engine to cool before you work on it, otherwise you could have problems removing the spark plugs.
