i hope this helps more. its hard to explain these things with out being at the car. but i hope this helps. it pretty easy just pull one wire off, unscrew plug from moter, replace with new one, replace with new wire. and repeat 4 or 6 times depending on what engine you have. but write back with anymore specific questions you have.
When you're removing spark plugs, work on one at a time. Don't start by removing the plug wires all at once, because, unless you number them, they may become mixed up. Take a minute before you begin and number the wires with tape.
When removing the spark plugs on the V-6 engine only on the firewall side, it may be necessary to remove the windshield wiper/motor module assembly from the vehicle. This will allow more room to work between the engine and the engine compartment firewall. Refer to for removal procedures.
Fig. 3: Hold the spark plug boot firmly, while giving it a slight 1/2 twist in each direction before pulling it off of the spark plug. remenber do this one at a time. replace the whole wire with new one.
- Disconnect the negative battery cable, and if the vehicle has been run recently, allow the engine to thoroughly cool.

Remove the spark plugs when the engine is cold, if possible, to prevent damage to the threads. If removal of the plugs is difficult, apply a few drops of penetrating oil(WD40) or silicone spray to the area around the base of the plug, and allow it a few minutes to work.
- On V-6 models only, remove the windshield wiper/motor module assembly from the vehicle for access to the spark plugs on the firewall side.
- Carefully twist the spark plug wire boot to loosen it, then pull upward and remove the boot from the plug. Be sure to pull on the boot and not on the wire, otherwise the connector located inside the boot may become separated.
- Using compressed air, blow any water or debris from the spark plug well to assure that no harmful contaminants are allowed to enter the combustion chamber when the spark plug is removed. If compressed air is not available, use a rag or a brush to clean the area.
- Using a spark plug socket that is equipped with a rubber insert to properly hold the plug, turn the spark plug counterclockwise to loosen and remove the spark plug from the bore.
Be sure not to use a flexible extension on the socket. Use of a flexible extension may allow a shear force to be applied to the plug. A shear force could break the plug off in the cylinder head, leading to costly and frustrating repairs.To install:
- Inspect the spark plug boot for tears or damage. If a damaged boot is found, the spark plug wire must be replaced.
- Using a wire feeler gauge, check and adjust the spark plug gap. When using a gauge, the proper size should pass between the electrodes with a slight drag. The next larger size should not be able to pass while the next smaller size should pass freely.
- Carefully thread the plug into the bore by hand. If resistance is felt before the plug is almost completely threaded, back the plug out and begin threading again. In small, hard to reach areas, an old spark plug wire and boot could be used as a threading tool. The boot will hold the plug while you twist the end of the wire and the wire is supple enough to twist before it would allow the plug to crossthread.
Do not use the spark plug socket to thread the plugs. Always carefully thread the plug by hand or using an old plug wire to prevent the possibility of crossthreading and damaging the cylinder head bore.
- Carefully tighten the spark plug. If the plug you are installing is equipped with a crush washer, seat the plug, then tighten about 1/4 turn to crush the washer. If you are installing a tapered seat plug, tighten the plug to specifications provided by the vehicle or plug manufacturer.
- Apply a small amount of silicone dielectric compound to the end of the spark plug lead or inside the spark plug boot to prevent sticking, then install the boot to the spark plug and push until it clicks into place. The click may be felt or heard, then gently pull back on the boot to assure proper contact.
