Early 99 PSD, Whats the Deal?

[Btheman]

Ok, I just looked at the date on the driver side, it says 08/1998 on my 1999 F250. I'm guessing that means I have the early 1999 F250 PSD?

If so, what do I need to look for, as in things I need to watch compared to the later 1999's?

Yes you have an early 99 build

The cut-off date is 12/8/98 IIRC

There are a dozen or two differences between them. Yoiu can find a list of the differences in the early 99 section I think.

[Southpaw]

Early 99 has a wicked wheel in it from the factory.

The early99 has 130cc(AB code) injectors and the late99-03 has 140cc(AD code) injectors.

The early99 has 2" intake runners. The late99-03 has 3" intake runners.

The early99 has a 15* swash plate HPOP. The late99-03 has a 17* swash plate HPOP.

The early99 has one glow plug relay. The late99-03 has one glow plug relay and one air intake heater relay side by side. Both relays are on the passenger side valve cover toward the front of the truck.

The early99 has a totally different air filter that is not inter changeable with the late99-03. But you can put the late99 air cleaner assembly in the early99 truck. The only two aftermarket air filters that work on the early99 are the AFE stage 2 and the AIS.

The early99 track rod has smaller mounting bolts than the late99-03. Stock rod replacement bushings, Prothane bushing part # is 61217BL.

The early99 has shallower rotors than the late99-03.

The early99 has shorter hub-bearings than the late99-03.

The early99 front axle U bolts are square where they go over the spring pack. The late99 U bolts are round.

The early99 has a different pitman arm than the late99-03.

The early99 does not have the AIH like the late99-03.

The early99 does not have the automatic transmission fluid cooler in the radiator.

The early99 has no indicator light showing that "cruise" is on. Late99-03 has a cruise light that will come on when you set the cruise control. Some of the early99 truck have this light in the dash already. A newer PCM(Yes it will plug in and will run better too) must be used to make the cruise light illuminate. It is a green light on the right side edge, half way up.

Thanks Chris...... Want to know all that I can....

The DIY intake will work on the early's.

[dieselcrawler]

the turbo housing is smaller on the E'99's, and the Powerstroke emblem is on the fender not the door... most of the time! Otherwise, great list Southpaw!
