How to install the Spark Plug for the 3.7L engine on Dodge Durango?

The 3.7L spark plug is installed after checking for proper spark plug gap with a gap gauging tool. Special care must be taken not to drop the plugs into the cylinder head spark plug wells as this will damage the electrodes. To avoid cross threading, first start the spark plug into the cylinder head by hand, then tighten to 27 Nm (20 ft. lbs.). Prior to installing the ignition coil, consider inspecting the coil O-ring and replacing it if needed. It is recommended to use silicone-based grease such as Mopar(R) Dielectric Grease to coat the rubber boot (spark plug end). Also coat the top of the spark plugs, and the O-rings on the coil. Finally, fit the ignition coil and all essential air filter tubing and air intake parts at the top of the engine and at the throttle body.

How to remove the Spark Plug located under each ignition coil on Dodge Durango?

Taking away the air filter tubing and air intake components at the top of the engine and at the throttle body will allow you to remove the spark plug which is located under each ignition coil. Before taking out the ignition coil, use compressed air around the base of the coil at the cylinder head. Next, use compressed air in spray form to blow away and enter the cylinder head opening. A high-quality socket with a rubber or foam insert should be used to remove the spark plug from the cylinder head. Check the condition of the ignition coil O-ring and replace as necessary. Examine the spark plug condition as well.
