Fluid types and weights

[venturesomerite]

I have a simple, but important questions.

My truck did not come with an owner's manual.

What weights and fluid types should I use in the various parts of my truck.

Early 99 F250 4x4 auto 7.3

Engine Oil:
Tranny Fluid:
Transfer Case Fluid:
Rear End Fluid:
Front End Fluid:
Power Steering Fluid:
Brake Fluid:

Washer Fluid: (lol, no, not really)

Thanks In advance,
Brian

Go to Official Ford, Lincoln & Mercury Owner Site | Personalized Owner Information
Click on Vehicle basics
Click on owners manuals and videos

That will take you to a page where you can get manuals online.

99's may not be there, but 2000 or 20001 should be the same.

Awesome, just what I'm looking for. Previous owner snatched the manual when doing the final "cleaning out" before I took the truck.

Engine Oil: Any CJ-5 diesel rated oil. I've run Motorcraft 15w40 and Rotella 5w40 synthetic with great results
Tranny Fluid: Mercon ATF
Transfer Case Fluid:Mercon ATF
Rear End Fluid: Synthetic 75w140
Front End Fluid: Synthetic 75w90
Power Steering Fluid:Mercon ATF
Brake Fluid: Dot 3

Early 99 F250 4x4 auto 7.3

Engine Oil: Any CJ-4 motor oil
Tranny Fluid: Mercon or according to FoMoCo Mercon V (it is been debated what will happen to your trans since when the 4R100 first came out Ford didn't spec Mercon V but now it says its ok to run it) Do a search for Mercon V, lots and lots of threads on it.
Transfer Case Fluid: Dex/Merc ATF
Rear End Fluid: Synthetic 75w-140 for SRW, 75w-90 for DRW
Front End Fluid: 75w-90, doesn't spec synthetic but it is not a bad idea
Power Steering Fluid: Mercon ATF
Brake Fluid: DOT 3

Washer Fluid: (lol, no, not really)

Do you guys use an additive to the coolant? My manual says I should but I have not.

If you have green coolant you should check it every 15k miles or so if gold I would check it once a year.

Instructions are in this for gold:

Or you could flush in an ELC and only need an additive every 3-4 years.

Thanks for the link. Is this good for the 7.3L?

Depends on the coolant you have in your 7.3.

If you have green you should follow this:

Under 6.9 and 7.3.

If you have Gold, you follow the same intervals as the 6.0s as in the link above. Basically you are checking the nitrate strength every 6 months and adding more as needed.

If you have ELC, you ignore both and just add an extender in 3-4 years depending on brand and run the coolant for 6-8 years total.

How much ATF does the transfer case hold?
