The Early
1999
PowerStroke
SuperDuty



Yeah this is me​

This was considered the odd truck, because some were made in early 1998 (like mine), they were considered early 1999 if they were made before 12/7/1998, it never received the 1998 name. Ford had stopped production for the 1998 model year in order to Modernize plant operations for the new body style (hence the 1994.5 thru 1997 were considered Old Body Style {OBS}).
"The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in (104.4 mm) bore and 4.18 in (106.2 mm) stroke creating a displacement of 444 cu in, (7.3 L)(Wikipedia)." Navistar designated it the T444E. "It has a 17.5:1 compression ratio, and has a dry weight of approximately 920 lbs. This engine produced up to 250 hp (190 kW) and 525 lb·ft (712 N·m) of torque in automatic trucks during the last years of production, and 275 hp (205 kW) and 550 lb·ft (746 N·m) of torque in manual trucks (Wikipedia)." Fuel was delivered via a frame mounted fuel pump, "Single turbocharged with a turbine housing size of 1.15 A/R (Wikipedia)." Air to air cooled, intercooler for those that don't know any better. Hydraulically actuated, Electronicaly controlled, Unit, Injector, the HEUI injectors were split shot AB code. The high pressure oil system for that year still utilized the 15 degree high pressure oil pump.

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.

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.

This is a live thread so please if you know anything about this type of unique vehicle please correct and/or add to this. All you have to do is cut and paste
