Scheduled Maintenence Guide
Picked up a used 2004 F150 4.6L XLT pickup a few months back. I'm looking to stay on top of scheduled maintenence. Is there a scheduled maintenence guide online for these trucks that I could pull up? I looked in the Owners Guide and it doesnt really specify when to change anything.
I'm at 68,000 miles. I just changed the engine oil and dropped in a K&N drop in filter. I also changed the fuel filter (it had the original one on it). I picked up a stant 195* thermostat and 2 gallons of Zerex Antifreeze coolant. Is it necessary to drain out the old coolant and change the thermostat at 70,000 miles? The coolant level looks ok, and the coolant doesnt look real bad, but it doesnt look cherry either.

I hope to drain the majority of the old coolant out. But irregardless, I believe I have what is recommended.

So I went through the scheduled maintenence guide. Pretty much standard for the most part as to what I saw. However, I did not see anything about changing the rear differential fluid? Isn't this something that is good to swap out every 75-100K miles ?

Take a look at page 46 of the guide I linked to above;
EXCEPTIONS
Normal Vehicle Axle Maintenance
❑ Rear axles and power take off (PTO) units containing synthetic lubricant and light duty trucks equipped
with Ford-design axles are lubricated for life. These lubricants are not to be checked or changed unless
a leak is suspected, service is required or the axle assembly has been submerged in water. The axle
and PTO lubricant should be changed anytime the axle and PTO have been submerged in water.
Non-synthetic rear axle lubricants should be replaced every 3,000 miles or 3 months, whichever occurs
first, during extended trailer tow operation above 21 Celsius (70 degrees Fahrenheit) ambient and
wide open throttle for extended periods above 45 mph. The 3,000 mile lube change interval may
be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification
WSL-M2C192-A, part number F1TZ-19580-B or equivalent. Add four ounces of additive friction modifier
C8AZ-19B546-A (EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles. The axle
lubricant should be changed anytime an axle has been submerged in water.
Police and Taxi Vehicle Axle Maintenance
❑ Replace rear axle lubricant every 100,000 miles. Rear axle lubricant change may be waived if the
axle was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part
number FITZ-19580-B or equivalent. Add four ounces of additive friction modifier C8AZ-19B546-A
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles. The axle lubricant should
be changed anytime an axle has been submerged in water.
E and F 450 and 550 Series Axle Maintenance
❑ Replace rear axle lubricant every 100,000 miles under normal driving conditions on all E and F 450
and 550 series applications. For E and F 450 and 550 series vehicles operated at or near maximum
Gross Vehicle Weights, the rear axle lubricant should be replaced every 50,000 miles. In addition, this
50,000 mile schedule should be observed when the vehicles are operated under the Special Operating
Conditions, where noted, on pages 43-44.
Reading that, I don't think you need to. But It couldn't Hurt.
