1-2-3-4-5-6...front cylinders from left to right...2-4-6
rear cylinders from left to right 1-3-5...Best results are AC plugs, and AC wires as replacing...Hope this helps (Be sure to check the
spark plug gap before installing...)
First, I would highly recommend that you also purchase a set of igniton cables and replace these also because you are most likely to have damaged spark plug boots when you remove the boots from the plugs. Trust me...it happens about 95% of the time, and you will be way ahead of the frustration if you are prepaired.
Pull the spark plug boots off of the spark plugs.
NOTE:
Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug threads to seize, causing damage to cylinder head threads.
Clean the spark plug recess area before removing the spark plug. (spray brake cleaner and compressed air works well) Failure to do so could result in severe engine damage because of dirt or foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper seating of the new plug. Use a thread chaser to clean the threads of any contamination.
Screw the spark plugs out of the cylinder head.
Check the air gap at the electrode end of the spark plug.
The specification for the plug gap on your vehicle is 1.524mm (0.060 in)
Place a SMALL amount of nickle-based antiseize compound on the spark plug thread, being very careful not to get any on the porcelain portin of the plug. If you do get antiseize on the porcelain part of the plug, it is imperative that you clean it off thouroughly using brake cleaner and a clean rag, otherwise it could cause cylinder misfires.
Screw the spark plug into the cylinder head and torque to specifications.
The spark plug torque specification for your vehicle is 15 Nm (11 ft. lbs.)
NOTE: Failure to properly torque the plugs can cause severe engine damage. Overtightening the plug can damage the threads in the cylinder head and/or make spark plug removal in the future impossible. This will cause you to have to remove the cylinder head for repair the next time the vehicle needs service on the spark plugs.
Undertightening can cause the plug to leak compression and damage the threads in the cylinder head. This can result in the plug blowing completely out of the head causing severe cylinder head damage.
When replacing the ignition cables, make sure they are routed EXACTLY as they were originally routed from the factory. Make sure that all protective wire loom and fasteners are transfered to the new wires and secured properly. Failure to do so can cause damage to the cables, engine misfires and can cause the spark plug wires to "spike" sensitive sensor circuits that are nearby and cause damage to the sensors or your computer modules. Improperly routed ignition cables have also been known to cause interference in radio and stereo systems.
HINT: The rear plugs on your engine are much easier to get to if you remove the two engine struts that go between the engine and the upper radiator support. You can then use a ratchet strap to pull the engine forward to get more room to work on the rear plugs.
did you bench bleed the master cylinder before putting it on car ! if not, you have air trapped in the lines and it needs bled out. if there is no leaks in system. have a good day !
The firing order is 1-4-3-2. From looking at the motor, cylinder 1 is right rear, cylinder 2 is right front, cylinder 3 is left rear, and cylinder 4 is left front.
First remove spark plug. #8 plug is, if sitting in truck, left rear plug. Have someone crank engine while you hold spark plug, connected to plug wire, ground plug to ground. Check spark. If no spark, remove plug wire from coil, connect test light from coil to ground, see if you get spark, if no spark replace coil. Leave cylinder #8 open to air to dry any unburnt fuel in cylinder.
Most likely does not have wires. It should have coil packs on the plugs. If it does have wires, should be the 1st cylinder on the drivers side of the engine in a V6, rear cylinder on passenger side of the V8.
Take The Spark Plug Wire Off at SPARK PLUG END Stick a Screwdriver in it to get good Contact Start Engine And HOLD Screwdriver Close to GROUND SURFACE 1/8 th Inch and see if there is a SPARK if there IS Suspect INJECTOR
The coil have these number 1,4,3,2 these are the cylinder number and the number 1 cylinder spark is the first of the left when you are in front of the car trunk the secuency is continuos in the motor from left to right 1,2,3,4.
