2002 F150 PU spark plug replacement question
Greetings,
In looking at the engine, I'm getting the impression that changing these plugs is gonna be a real chore. Looks like I might have to remove the fuel rail feeding the injectors and the rear 2 plugs are going to be hard to get to even after the rail is out of the way. Is it as bad as I think? Thanks, Gary |

You may want to procure a 8mm 1/4" drive flex socket for the screws that hold the coils down. (double check the 8mm) Uncomfortable job, but not that terrible. Replace the plug boots as long as you have it apart. DO use an accurate torque wrench when tightening the plugs, they have 'problems.' Be glad it's not a three valve 5.4 |

Just remove the small screws that hold the coils in place, then the coils will flex enough to come out past the fuel rail?? Rest is usual care to not bust a knuckle or strip any threads??? I have a 1/4" drive universal joint for my socket set as well as a flex drive. Thanks for the advice so far. Anyone know for sure what the torque is for the plugs? I do have a torque wrench. Gary |

Ditto on the torque wrench. These engines like to blow the plugs right out of them. |

I took my time and finished all 8 plugs in about 2 1/2 hours w/ no blood drawn. All the plugs broke free with relative ease. The aftmost plug on the passenger side was a bit of a challange, but not bad. Same for the driver side, but the drive side in general was a bit easier since the plugs actually face slightly forward. The coils on the plugs are actually a lot more flexible than one might guess. Once the 7mm screw is removed then it's very easy to pull them out. Highly recommend compressed air to blow out the plugs before removal. Definitely a very doable job. Gary |
