5.4 tune up

My work truck is a 2007 F150 w/ 5.4 coming up to 100,000 miles, what should be included in the first tune up? No issues to date! Oil changes @ every 5k miles, fuel filter changes @ 15k and air filter as needed.

I would change spark plugs, all your fluids- coolant, trans (at least drop the pan, new screw and top off), serpentine belt. Didn't say if 4x4 or not, but I would change axles and t-case if it was.

If you have not done so already the PCV Valve should be replaced and most likely the wires for the plugs.

If it is only a 2wd then you would need to do the rear differential fluid.

You need plugs, PCV and the normal service items: oil change, rotate tires, new fuel filter, air filter, etc. Your ATF is good until 150K, however a simple drain and fill will suffice for now if you're concerned about it.

Also...these are coil-on-plug trucks, no spark plug wires...

ATF...Automatic Transmission Fluid. According to the service manual the PCV valve should be replaced. However, it wouldn't be the first time the service manual said replace something that doesn't exist or is unserviceable

Doesn't the transmission filter need to be changed?

The transmission filter can be changed if you change the fluid. I prefer to change them myself but you do not get all of the fluid out when you drop the pan. Only a flush does that. When you change the plugs you shouldat least change the COP boot/wire. I changed to a set of Accel COP's from Summit when I did mine and used Champion #7989 one piece plugs. The coils were personal preference though. If you are doing them yourself strickly follow the TSB and have a Lisle #65600 tool set on hand. Also the 9/16" spark plug socket neede to get the old plugs out. Let the plugs soak OVERNIGHT!!!! Trust me on this, I broke nearly all of mine at 71,000 miles. Ditto on all of you fluids.
