Default 100,000 mile maintenance check

How much is the 100k and 105k maintenance check for an 05 F-150? And I can't remember if it's the 100k or 105k where the timing belt gets replaced so I would also need to know that. Much appreciated!

There's not really an answer for any of your questions. We don't know what motor you have. Every dealer charges different. Or are planning on doig this your self? Also you don't have a timing belt you have a time chain.

The owners manual describes the checks/maintenance required at the 100K mark.

Or, a quick trip to your local Ford service department will get you a free copy of what Ford recommends.

I posted a link last week to get a free PDF version of your owners manual if you do not have one. The same link will also create a maintenance schedule for you too (what gets changed at what mileage interval based on how you drive the truck).

Two timing chains.. And they don't get replaced as maintenance.

Basically at 100k you need to do your coolant, trans fluid if you haven't yet, I like to do that at 60k intervals.. and your spark plugs. Air filter I just check every once in a while and replace when it's dirty, fuel filter needs to be at least every 30k miles. I usually do mine at 25k.

If you have never changed your rear fluid you definitely want to do that, and if you have a 4x4 the transfer case and front diff should be done as well.

Check your power steering fluid, if it's brown you want to flush that out, just get a suction gun and with the truck running suck bad fluid out then pour good fluid in till it's clean, and it's not a bad idea to flush your brakes, but meh. If you want to go nuts I'd do an air induction to clean the intake all out and a can of BG 44k or seafoam for the fuel tank, lines and injectors.

If you want a dealer to do all that you're looking at like a $1200, but the diffs and transfer case are easy, probably $100 in fluids. Coolant is easy, just take the cap off and drain it out the bottom of the radiator and fill it up, run it till the bubbles stop. air and fuel filters aren't bad. Plugs aren't bad, let the truck idle for a half an hour and heat up and the plugs almost always come right out, get a 7mm 1/4" swivel socket for the coil bolts, and you might want to pick up the Lisle broken plug remover just in case.

Good advice all around however if you have a 5.4l I would plan on the spark plugs breaking.

Nah, when you idle the truck for a half hour or so and let it get hot they usually come right out. I use a short 3/8" ratchet instead of a long one on them and it tends to help keep them from breaking. Work them back and forth and they're not bad.
