Specifications Torque:
Extensive torque specifications for all critical fasteners, engine component clearances, and alignment data.
Diagnostic Tools:
While not explicitly listing modern scan tools, the manual provides the foundation for using basic diagnostic tools like multimeters, timing lights, and vacuum gauges for troubleshooting.
Engine Options:
4.2L (255 ci) V8, 5.0L (302 ci) V8, 5.8L (351 ci) V8, 6.6L (400 ci) V8, 7.5L (460 ci) V8
Horsepower Torque:
Varies by specific engine and year. For example, a 1975 5.0L V8 might produce around 150-170 hp, while a 1980 7.5L V8 could be in the 220-240 hp range (figures are approximate and dependent on specific calibration and emissions controls).
Fuel Delivery:
Primarily carbureted (e.g., Motorcraft 2-barrel or 4-barrel carburetors). Later models may feature early electronic fuel injection (EFI) systems on some engine variants.
Block Material:
Cast Iron
Cylinder Head Material:
Cast Iron
System Type:
Conventional breaker-point ignition early in the range, transitioning to electronic ignition systems (e.g., Duraspark) on later models.
Automatic Transmission:
Likely Ford C6 3-speed automatic (heavy-duty applications) or Ford AOD 4-speed automatic (overdrive transmission) depending on engine and year.
Manual Transmission:
Manual transmissions were rare or unavailable on higher trim LTD models, especially with larger V8 engines, during this period. If offered, it would likely be a heavy-duty 3 or 4-speed unit.
Overdrive:
Ford AOD transmission offers a 4th gear overdrive for improved fuel economy on the highway.
Automatic Transmission Fluid:
Typically Mercon/Dexron II for C6 and AOD transmissions. Consult manual for specific fill capacities.
Audio Systems:
Standard AM/FM radio, optional AM/FM stereo, cassette player, and premium sound systems. Features like power antennas were often optional.
Cruise Control:
Optional speed control (cruise control) available on many models.
Climate Control:
Manual or optional automatic climate control systems, including air conditioning.
Power Features:
Power steering, power brakes, power windows, power door locks, and power adjustable seats were common options to enhance comfort.
Oil Change:
Typically every 3,000 to 5,000 miles (4,800 to 8,000 km) or 6 months, depending on driving conditions and oil type used. Manual will specify exact intervals.
Tune Up:
Spark plugs, distributor cap, rotor, and ignition wires typically recommended every 20,000 to 30,000 miles (32,000 to 48,000 km).
Engine Oil:
API Service SG or SF category oil. Viscosity grade depends on ambient temperature, typically SAE 10W-30 or 10W-40. Consult manual for specific recommendations.
Coolant:
Ethylene glycol based antifreeze with a 50/50 mix of antifreeze and water. Capacity varies by engine, typically 5-7 gallons (19-26 liters).
Common Wear Items:
Suspension bushings, ball joints, tie rod ends, exhaust components, ignition components (points, condenser, coil), and carburetor issues due to age and material degradation.
Body Corrosion:
Rust formation, particularly in fender wells, rocker panels, door bottoms, and trunk floors, is a common concern for vehicles of this age and vintage.
Ford Full Size:
The Ford LTD was the flagship full-size sedan for Ford for many years, representing luxury, comfort, and power in the American automotive market.
Fourth Generation Changes:
This generation saw downsizing efforts in response to fuel crises, with the LTD becoming more aligned with the Panther platform shared with the Mercury Grand Marquis and Lincoln Town Car. Styling evolved from the larger 1973-1978 LTD to the more aerodynamic and efficient designs of the later years.
Platform Sharing:
The Panther platform was a significant development, offering improved chassis dynamics and fuel efficiency compared to earlier body-on-frame designs, while maintaining rear-wheel drive.
Manufacturing Locations:
Primarily assembled in the United States (e.g., Chicago Assembly Plant, Twin Cities Assembly Plant, St. Louis Assembly Plant).
