Horsepower Torque Range:
Varies significantly by engine and year, generally ranging from ~115-145 hp and ~240-300 lb-ft for I6 engines, to ~180-230 hp and ~300-370 lb-ft for V8 engines. Diesel engines offer higher torque.
Fuel Delivery:
Carbureted (e.g., Motorcraft 2150, 4350) for earlier models and some base engines, transitioning to Electronic Fuel Injection (EFI) or Multi-Port Fuel Injection (MPFI) for later models and higher trims.
Fuel Type:
Unleaded gasoline (Octane ratings specified in manual), Diesel for diesel variants.
Specific Engine Codes:
Manual would likely list specific engine codes for each displacement and configuration (e.g., 300-6, 302-V8, 351W-V8, 6.9L IDI).
Manual Transmission:
Typically a 4-speed or 5-speed manual transmission (e.g., NP435, T-18, T-19, M5OD-R2).
Automatic Transmission:
Commonly offered automatic transmissions include the C6 3-speed, AOD 4-speed overdrive (later models), E4OD 4-speed overdrive (later models, often with diesels).
Transfer Case:
For 4WD models, manual or electronic shift transfer cases (e.g., NP208, NP231, BW1356) will be covered.
Transmission Gear Ratios:
Specific gear ratios for each manual and automatic transmission model will be detailed within the manual, crucial for performance and driveline calculations.
Wheelbase Options:
Various, typically including 117.4 inches (standard cab, short bed) up to 133.0 inches or more for long beds and crew cabs (though F-100 was primarily single cab).
Bed Length Options:
Typically 6.5 ft (short bed) and 8 ft (long bed).
Gvwr:
Gross Vehicle Weight Rating varied by configuration, generally starting around 5000 lbs and increasing for heavier-duty applications. The F-100 nomenclature was often used for lighter-duty configurations within the F-Series range.
Curb Weight:
Curb weight varied significantly based on configuration (engine, transmission, cab, 2WD/4WD), typically ranging from approximately 3,800 lbs to over 5,000 lbs.
Oil Change Interval:
Typically every 3,000 to 5,000 miles or 3-6 months, depending on engine type, usage (severe vs. normal), and oil quality. Manual will provide specific recommendations.
Transmission Fluid Change:
Approximately every 30,000 to 60,000 miles, or per severe service schedule. Manual will specify fluid type and capacity.
Coolant Flush:
Typically every 30,000 to 100,000 miles or 2-5 years, depending on coolant type (conventional, HOAT, OAT). Manual will specify type and interval.
Engine Oil Type:
Varies by engine, but commonly SAE 5W-30, 5W-40, or 10W-30 API Service SG, SH, or higher. Diesel engines may require specific diesel engine oils.
Transmission Fluid Type:
Automatic Transmissions: typically MERCON or MERCON V. Manual Transmissions: GL-4 or GL-5 gear oil, viscosity depending on temperature (e.g., 75W-90, 80W-90).
Coolant Type:
Typically a 50/50 mix of ethylene glycol antifreeze and distilled water. The manual will specify Ford's recommended coolant type (e.g., Ford Premium Gold or Universal Green).
Brake Fluid Type:
DOT 3 or DOT 4, as specified by Ford. Manual will confirm precise requirement.
Power Steering Fluid:
Ford's recommended power steering fluid or equivalent specification (e.g., Mercon ATF in some older models).
Engine Management Early Efi:
Early EFI systems could be prone to sensor failures (e.g., MAF, TPS, O2 sensors) and vacuum leaks affecting idle and performance.
Carburetor Issues:
Carbureted engines may require regular cleaning, adjustment, and potential rebuilds due to age and fuel quality.
Rust And Corrosion:
Common issue in many older vehicles, particularly in areas exposed to salt and moisture. The manual will provide guidance on body panel care and repair.
Suspension Wear:
Components like ball joints, tie rod ends, and bushings in the Twin-I-Beam front suspension can wear over time, leading to alignment issues and play in steering.
Ford Truck Legacy:
The Ford F-Series is the best-selling truck line in America and has a long-standing reputation for durability, capability, and innovation since its introduction.
Ninth Generation F Series:
1980-1986 saw a significant redesign with a more aerodynamic, downsized body, improved interiors, and the introduction of electronic fuel injection on some engines. The F-100 remained as a key model in the lineup.
Tenth Generation F Series:
1987-1991 introduced another major redesign featuring a more rounded, aerodynamic exterior, a refined interior, and the introduction of the Electronic Engine Control (EEC-IV) and more advanced fuel injection systems. The F-100 designation continued, though its positioning within the F-Series lineup evolved.
Manufacturing Locations:
Various Ford assembly plants across North America (e.g., Dearborn, Louisville, Kansas City).
