i recently purchased a 2014 STX 5.0 4x4. It had a few more miles (100,000+) than I would prefer but it was one owner and it was highway miles. plus the truck was in excellent condition, unmolested (i.e. everything stock) and it was a good deal. runs and drives excellent

however - the maintenance records were spotty - the previous owner did do oil changes but not much else.

i did the oil, front and rear diff. and transmission fluid - its winter and my garage is full - so plugs, wires etc will wait until spring.

what other maintenance should i perform?? is there anything 5.0 specific that i need to do??

thank you in advance RR

I bought mine at 95,600 and it has 125,250 now. Here's what I've done:

Rear diff
Trans. filter and fluid
T-case fluid
Spark Plugs
Coolant flush
New drive belts
Throttle body cleaning
Front and rear rotors and pads


Otherwise it's just basic upkeep...5W30 Motorcraft oil and filter with the oil life monitor reset to 80% each time.

drive belts relatively new. the brakes and the coolant flush were done at the stealership before i purchase the vehicle.

will do the throttle body and spray the MAF in the spring.

i didn't know if i should run seafoam or some other snake oil through the engine?? i am skeptical of such additives and have never used it on other engines. the only reason i consider it is that i have never had an engine with this many miles without knowing maintenance history etc (my former ranger 4.0 had belonged to my father so i know what was done or not done to the truck)

If it's running fine I wouldn't worry about putting any "snake oil" in the engine.

Does it still have the OEM shocks? If so, replace them with Bilsteins.

A bottle of sea foam into the fuel does work well,found that out after changing a bad fuel pump,also gained about 2 mpg after all was said and done

Plugs for sure. MOTORCRAFT ONLY & Regardless what the place you get them from they says check the gap and make sure its correct before installing.


Air Filter?


If you have access to a SCT programer, it can be anybodys, you can use it to reset the KAM. They will reset all the apdative learning the truck has done since the last time its been done if at all. Doing this will allow the truck to learn your driving style and adjust accordingly.


Dont be worried about the miles, 100K isnt that many miles now a days. I have friends with 120Kish on there 2013 F150s and they still run, drive and look like there new.

ALL the usual tune up stuff done - including air filter. The plugs and wires - that will wait until spring. And yes check those gaps!

I always used Motorcraft replacement parts (when they were available) for the old ranger.

I think at this point it comes down to "if ain't broke, don't fix it" lol

A new fuel filter always make a vehicle happy!
