What Problems Does the 1991 Ford F-250 Super Duty Have?
The 1991 Ford F-250 Super Duty, while revered for its toughness, does have several frequently reported problems and long-term reliability concerns.
Recalls: Specific recalls for the 1991 F-250 are less common now but historically included issues like faulty cruise control deactivation switches which could lead to fires (a widespread Ford recall affecting many models of the era) and fuel tank selector valve problems. Owners should always check NHTSA records for any open recalls related to their specific VIN.
Long-Term Reliability Concerns:
Recalls: Specific recalls for the 1991 F-250 are less common now but historically included issues like faulty cruise control deactivation switches which could lead to fires (a widespread Ford recall affecting many models of the era) and fuel tank selector valve problems. Owners should always check NHTSA records for any open recalls related to their specific VIN.
Long-Term Reliability Concerns:
- Rust: This is arguably the biggest enemy. Frame rust, bed rust (especially around the wheel wells and supports), cab corners, and rocker panels are common failure points, particularly in areas exposed to road salt.
- Transmission Issues: The E4OD automatic transmission, often paired with the 7.5L gas or 7.3L IDI diesel, is notorious for premature failure if not meticulously maintained. Regular fluid and filter changes are crucial, and overheating can quickly destroy it. Manual transmissions (like the ZF5) are generally more robust.
- Fuel System Problems: For gasoline engines, fuel pumps (in-tank and frame-mounted) are common failure items. Fuel injectors or carburettor issues can also arise with age. Diesel models can experience issues with the injector pump or glow plug system.
- Steering & Suspension Wear: Heavy-duty usage and age lead to worn-out kingpins (or ball joints on some models), tie rods, drag links, and steering gearboxes, resulting in loose and imprecise steering. Leaf springs can also sag over decades of heavy loads.
- Brake System: Master cylinder failures, sticky calipers, and issues with the Rear Anti-lock Brake System (RABS) are common age-related brake concerns.
- Electrical Gremlins: Aging wiring harnesses, faulty alternators, starters, and issues with the instrument cluster (especially the circuit board) can manifest as intermittent electrical problems.
- 7.3L IDI Diesel Specifics: While generally durable, these engines can suffer from cavitation in the coolant system if the proper SCA (Supplemental Coolant Additive) is not used, leading to block damage. Injector pump wear and glow plug system failures are also common.
- Interior Degradation: Dashboard cracks from sun exposure, worn-out seats, sagging headliners, and brittle plastic trim are typical for a vehicle of this vintage.
How long will the 1991 Ford F-250 Super Duty last?
Based on owner data and proper maintenance habits, a 1991 Ford F-250 Super Duty can easily achieve 200,000 to 300,000 miles, with many 7.3L IDI diesels and 4.9L I6 gasoline engines known to exceed 400,000 miles. These trucks are celebrated for their long-term durability, often serving over 30 years if cared for. Their robust, mechanically simple design contributes significantly to this longevity. However, weaknesses over time include pervasive rust on the frame and body, degradation of rubber components like hoses and seals, and wear in steering and suspension components from heavy use. The E4OD automatic transmission is a particular long-term concern if maintenance is neglected. Overall, it's an exceptionally durable truck, but age and heavy use will necessitate ongoing attention to rust prevention and component wear.
What Technology & Safety Features are Included?
The 1991 Ford F-250 Super Duty predates most modern automotive technology, offering a "built-in tech" suite that is remarkably sparse by today's standards. The most advanced systems would involve electronic fuel injection (EFI) on some gasoline engines, replacing older carbureted designs, but complex engine control units (ECUs) were rudimentary compared to contemporary vehicles.
For entertainment, standard features included an AM/FM radio, with an optional AM/FM cassette player for higher trims. There were no CD players, Bluetooth connectivity, USB ports, or advanced infotainment screens – just basic audio functionality.
Driver-assistance features, as understood today, were entirely absent. The F-250 offered fundamental aids like power steering and power brakes (vacuum-assisted for most gasoline models, and hydroboost for diesel or heavy-duty gasoline configurations to handle the increased braking demands). There was no traction control, stability control, cruise control (though an optional feature), blind-spot monitoring, lane-keeping assist, or automatic emergency braking.
Safety features were also minimal compared to modern standards. The primary passive safety systems included three-point seatbelts for front occupants. Anti-lock Rear Brakes (RABS) was a significant safety advancement for the time, likely standard or optional on the 1991 F-250, preventing only the rear wheels from locking up during hard braking. There were no airbags; driver's side airbags became mandatory for light trucks later in the decade. The truck's robust, body-on-frame construction provided a degree of inherent strength.
Optional comfort and convenience features that were considered "tech" at the time included air conditioning, power windows, and power door locks, primarily available on XLT Lariat trims.
Crash-test ratings from independent organizations like NHTSA or IIHS are not available for the 1991 Ford F-250. Standardized, publicly reported crash tests for heavy-duty trucks were not commonplace at that time. Given the lack of airbags, crumple zones, and advanced safety structures, a vehicle of this vintage would perform very poorly in modern crash tests. Its sheer mass offered some protection in certain scenarios, but occupant protection was far less sophisticated than in today's vehicles.

1991 Ford F-250 Super Duty Cost of Ownership
Insurance costs for a 1991 Ford F-250 are generally low for basic liability due to its age and lower market value, though comprehensive coverage might be higher for unique classic vehicle policies. Fuel costs are significant; gasoline engines are very thirsty (8-15 MPG), and while the diesel offers better economy (15-20 MPG), diesel fuel itself can be pricey. Maintenance can be economical for DIYers, given its mechanical simplicity and widely available, inexpensive parts. However, shop labor for more complex repairs, like an E4OD transmission rebuild, can be costly. Long-term ownership is a mixed bag: low initial purchase price and simple maintenance (if DIY) are offset by high fuel consumption and inevitable age-related repairs. It's economical as a workhorse, but not in terms of fuel efficiency.

How Does the 1991 Ford F-250 Super Duty Compare to Other Vehicle?
The 1991 Ford F-250 Super Duty competed fiercely with the Chevrolet C/K 2500 / GMC Sierra 2500 (GMT400 platform) and the Dodge Ram D/W 250 (first-generation).
In terms of performance, Ford's 7.5L gasoline V8 and the robust 7.3L IDI diesel were strong contenders for towing and hauling. Chevrolet offered the powerful 7.4L (454) gasoline V8 and the less-regarded 6.2L/6.5L Detroit Diesel. Dodge brought its venerable 5.9L Cummins turbo-diesel, which often outclassed both Ford's and Chevy's diesel offerings in torque and longevity, alongside its 360 (5.9L) gasoline V8. While Ford's engines were excellent workhorses, the Cummins-powered Dodge often had an edge in sheer diesel capability.
Features across all three were quite basic. Ford's XLT Lariat trim offered comparable comfort and amenities to Chevrolet's Silverado trim, both generally more refined than Dodge's more utilitarian interiors. None offered the advanced tech, entertainment, or driver-assistance features found in modern trucks.
For reliability, Ford's 4.9L I6, 7.3L IDI, and 7.5L V8 engines were highly durable, though the E4OD automatic transmission was a known weak point. Chevrolet's big-block 454 was reliable, but their diesels had more reported issues. Dodge's Cummins engine was legendary for reliability, often outlasting the rest of the truck, which sometimes suffered from weaker body and interior components compared to Ford and Chevy. All three were prone to rust depending on climate.
Price, when new, was competitive. Today, used market prices reflect these reliability perceptions: Cummins-powered Dodges generally command the highest prices. Clean, 7.3L IDI Fords are next, followed by Chevrolet models, though condition is the biggest variable.
Similar alternatives include the 1988-1991 Chevrolet C/K 2500 with the 7.4L 454 V8 for a strong gasoline option, or the 1989-1993 Dodge Ram D/W 250 with the 5.9L Cummins diesel if the absolute best diesel engine of the era is the priority. The 1991 F-250 Super Duty remains a fantastic choice for those seeking a balance of proven durability, strong capability, and classic American truck styling, especially if equipped with the 7.3L IDI or 4.9L I6.
