- To remove spark plugs without damage, it is necessary to adhere exactly
to this procedure before removal is attempted.
- CAUTION: DO NOT REMOVE PLUGS WHEN THE ENGINE IS WARM OR HOT. THE
ENGINE MUST BE AT ROOM TEMPERATURE WHEN PERFORMING SPARK PLUG SERVICE.
REMOVING THE SPARK PLUGS FROM A WARM/HOT ENGINE INCREASES THE CHANCE THE
THREADS COULD BE DAMAGED.
- Spark Plug Removal Procedure
- Remove the coil-on-plug assemblies and thoroughly blow out the spark
plug wells and surrounding valve cover area with compressed air.
Back out the spark plugs no more than 1/8 to 1/4 of a turn. Using
Motorcraft® Carburetor Tune-Up Cleaner, fill the spark plug well just
above where the jamb nut hex sits (1/2 - 3/4 teaspoon). A minimum period
of 15 minutes of soak time is required. The cleaner will wick down to
the ground electrode shield and soften the carbon deposits in this time.
DO NOT WORK the spark plug back and forth at this point.
- NOTE: COMPLETELY REVIEW THE PRODUCT LABEL FOR THE MOTORCRAFT CARBURETOR
TUNE-UP CLEANER PRODUCT - USE AT ROOM TEMPERATURE AND SHAKE WELL.
- CAUTION: EXCESSIVE MOTORCRAFT® CARBURETOR TUNE-UP CLEANER, OR
REPEATING THE PROCESS SEVERAL TIMES WITH TOO MUCH CLEANER FLUID, COULD
INTRODUCE ENOUGH LIQUID VOLUME TO HYDRO-LOCK THE ENGINE.
- CAUTION: DO NOT USE AIR OR POWER TOOLS FOR SPARK PLUG REMOVAL. SPARK
PLUGS MUST ONLY BE REMOVED WITH HAND TOOLS.
- Tighten, and then loosen the spark plug, working the plug back and
forth. Some screeching and high effort may be noticed. The expected
removal torque is about 33 lb-ft (45 N-m). Repeat the back and forth
turning as needed until turning effort is reduced, and remove the spark
plugs.
- NOTE: NEW PLUGS SHOULD BE INSTALLED USING A FILM COATING OF MOTORCRAFT
HIGH TEMPERATURE NICKEL ANTI-SEIZE LUBRICANT ON THE GROUND ELECTRODE
SHIELD. DO NOT COAT THE ELECTRODE STRAP.
- Torque spark plugs to 34Nm (25 lb-ft). Reinstall the coils. Torque the
coil bolts to 6Nm (4.5 lb-ft).
