The frequency at which spark plugs should be changed on a Ford Expedition can vary depending on the model year and engine type. Let’s explore the information available to determine the recommended interval.
Recommended Procedure for Spark Plug Removal
According to a service bulletin issued by Ford (08-7-6), the spark plugs in the Ford Expedition can be difficult to remove. To minimize the risk of breaking a spark plug, Ford recommends the following procedure :
1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the threads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.
Spark Plug Change Interval
The recommended interval for changing spark plugs can vary depending on the model and engine type. Here are some examples:
– For Ford F-150 models, spark plugs should be changed or replaced once every 60,000 miles.
– For some Ford vehicles, including the Expedition, spark plugs may need to be changed every 30,000 miles.
It’s important to note that these intervals are general recommendations and may vary based on factors such as driving conditions and the specific engine configuration. It’s always a good idea to consult your vehicle’s owner’s manual or contact a Ford dealership for the most accurate information regarding spark plug replacement intervals for your specific Ford Expedition model.
