Changing Nitro Plugs 4.0L
If you have the 3.7 engine in your Nitro use this Thread.
I have attempted in separating "Changing Nitro Plugs 3.7 & 4.0L" into two THREADS. One for each engine type, since there are differences mainly the requirement of removing the intake manifold on the 4.0L (R/T) engine to end any confusion. I did not remove the posts concerning the 4.0 engine from the original thread but did mark them in RED.
Hopefully this will help.
The 3.7 liter (226 CID) six-cylinder engine is an 90° single overhead camshaft engine. The cast iron cylinder block is made up of two different components; the first component is the cylinder bore and upper block, the second component is the bedplate that comprises the lower portion of the cylinder block and houses the lower half of the crankshaft main bearings. The cylinders are numbered from front to rear with the left bank being numbered 1, 3, and 5 and the right bank being numbered 2, 4, and 6. The firing order is 1-6-5-4-3-2. The engine serial number is located at the right front side of the engine block.
The 4.0L Liter (244 Cubic Inches) 60° V-6 engine is a single overhead camshaft design with hydraulic lifters and four valves per cylinder The engine does not have provisions for a free wheeling valve train. The cylinders are numbered from front to rear, with the right bank odd numbered, and the left bank even numbered The firing order is 1-2-3-4-5-6. The engine identification number (2) is located on the rear of engine block just below the left cylinder head
