1986 Ford F-350 Super Duty: Quick Overview
- Engine Options: The 1986 Ford F-350 Super Duty offered a range of robust powertrains to suit heavy-duty needs. These included the venerable 4.9L (300 cu in) Inline-6 for basic reliable power, the more common 5.8L (351 cu in) Windsor V8, and the potent 7.5L (460 cu in) big-block V8 for maximum gasoline power. For serious towing and efficiency, the naturally aspirated 6.9L Navistar IDI Diesel V8 was a popular choice.
- Horsepower: Horsepower figures varied significantly by engine. The 4.9L I6 typically produced around 115-125 hp. The 5.8L V8 ranged from approximately 150-185 hp. The powerful 7.5L 460 V8 generated between 225-245 hp. The 6.9L IDI Diesel V8 offered around 170 hp and substantially more torque.
- Fuel Economy: Given their heavy-duty nature, fuel economy was not a strong suit. Gasoline V8s typically achieved 8-12 MPG, while the I6 might see 10-14 MPG. The 6.9L Diesel was the most "economical" option, often delivering 12-16 MPG, depending on load and driving conditions.
- 0-60 MPH Times: These trucks were built for work, not speed. 0-60 MPH times were generally slow, often in the 12-18 second range, heavily dependent on engine, drivetrain, and whether the truck was loaded.
- Towing Capacity: Towing capacity was a major selling point. While specific numbers varied by configuration (engine, axle ratio, transmission, 2WD/4WD, single rear wheel vs. dually), the F-350 Super Duty could tow from roughly 7,000 lbs in lighter configurations up to an impressive 14,000 lbs with the 7.5L V8 or 6.9L Diesel in a dually setup, with appropriate trailer brakes and hitch.
- Trim-Level Features:
- Custom: This was the base work truck, featuring vinyl seating, rubber floor mats, manual windows and locks, and minimal amenities.
- XL: A step up, offering some cloth/vinyl seating options, a bit more exterior chrome trim, and an AM radio.
- XLT Lariat: The top-tier trim provided more creature comforts, including plush cloth upholstery, full carpeting, power windows, power door locks, air conditioning, cruise control, a tilt steering wheel, and an upgraded audio system. Exterior styling included more chrome accents and often two-tone paint schemes.

What Problems Does the 1986 Ford F-350 Super Duty Have?
The 1986 Ford F-350 Super Duty, while revered for its durability, is not immune to a specific set of frequently reported problems, largely due to its age and intended heavy usage. Foremost among these is rust, which commonly affects the frame, cab corners, rocker panels, floorboards, fender wells, and bed seams, especially in regions exposed to salt. Buyers should thoroughly inspect these areas for structural integrity.
Fuel system issues are also prevalent. Gasoline engines, often equipped with carburetors, can suffer from common carb-related maladies like rough idling, stalling, and poor fuel delivery. Fuel pump failures and problems with the dual-tank fuel selector valve are also known, with the latter sometimes being linked to fire risks and subject to past recalls. For the 6.9L IDI Diesel, owners frequently encounter issues with glow plug controllers and the glow plugs themselves, impacting cold starting. Fuel filter clogging can also occur if maintenance is neglected.
Electrical gremlins are another common complaint. Deteriorating wiring harnesses can lead to intermittent issues with lights, gauges, power windows (on XLT Lariat trims), and the instrument cluster. Grounding issues are also a frequent culprit.
Steering and suspension components are subject to significant wear over decades of heavy service. Worn ball joints, tie rod ends, kingpins (on 4WD models), leaf springs, and various bushings are common culprits, leading to sloppy steering and a less controlled ride. Brake system components, including master cylinders and vacuum boosters, can also fail with age.
Regarding recalls, the 1986 F-Series did have specific campaigns. Notably, there were recalls concerning the fuel tank selector valve, which could potentially fail and cause fuel to leak, posing a fire hazard. Another recall involved power steering pump hoses that could rupture. Prospective owners should verify if these recall services were performed. Long-term reliability is generally high for the core mechanicals, but age inevitably brings a need for diligent preventative maintenance and component replacement.
How long will the 1986 Ford F-350 Super Duty last?
The 1986 Ford F-350 Super Duty boasts exceptional long-term durability, with many examples still operating reliably today after 30-40+ years of service. Based on owner data and proper maintenance habits, it's not uncommon to see these trucks exceed 200,000 to 300,000 miles on their original powertrains. Engines like the 4.9L I6 and 6.9L IDI Diesel are particularly renowned for their longevity, often reaching well over 400,000 miles with diligent care. The robust frame and heavy-duty drivetrain components were engineered to withstand significant abuse.
However, weaknesses emerge over time. Rust remains the primary long-term threat, progressively attacking body panels and the frame if not addressed. Electrical systems can become temperamental as wiring deteriorates. Rubber and plastic components in the engine bay and interior become brittle and crack. While core mechanicals are strong, ancillary systems and body integrity require consistent attention to ensure continued reliable service.

What Technology & Safety Features are Included?
The 1986 Ford F-350 Super Duty, a product of its era, featured technology, entertainment, and safety systems that were rudimentary by modern standards but entirely adequate for its time. Built-in technology was largely mechanical. The gasoline engines utilized carburetors for fuel delivery and ignition systems were points or basic electronic ignitions, while the diesel relied on a mechanical injection pump. There were no integrated engine management computers as seen in later models; diagnostics were primarily visual and mechanical.
For entertainment, the F-350 typically came standard with an AM radio, with an optional upgrade to an AM/FM stereo and, in higher trims, a cassette player. Speaker setups were basic, usually a pair of speakers in the dashboard or doors.
Driver-assistance features were limited to fundamental aids like power steering, which was either standard or a widely selected option, and power-assisted brakes. There were no electronic stability control, traction control, anti-lock brakes (ABS), or advanced driver-assistance systems (ADAS) like lane keeping assist or adaptive cruise control. The driving experience was purely mechanical and required full driver engagement.
Safety features were also basic. Standard equipment included three-point seat belts for front occupants and lap belts for rear passengers (in Crew Cabs). The truck featured a robust ladder frame and heavy-gauge steel body construction, offering a degree of passive protection. However, there were no airbags, advanced crumple zones, or side-impact protection as defined by contemporary standards. Crash-test ratings from agencies like NHTSA or IIHS are not available for vehicles of this vintage, as testing methodologies and requirements have evolved dramatically since the mid-1980s. Optional comfort features included air conditioning, cruise control, power windows and door locks (exclusive to XLT Lariat), and a tilt steering wheel, which improved driver comfort but not necessarily safety or advanced tech.
