The Ford F-Series is a series of light-duty trucks marketed and manufactured by Ford Motor Company since the 1948 model year. The F-Series is marketed as a range of full-sized pickup trucks positioned above the midsize Ranger but below the larger Super Duty in the Ford truck lineup. Alongside the F-150 (introduced in 1975), the F-Series also includes the Super Duty series (introduced in 1999), which includes the heavier-duty F-250 through F-450 pickups, F-450/F-550 chassis cabs, and F-600/F-650/F-750 Class 6–8 commercial trucks.

History

The F-Series was first introduced in 1948 as a replacement for a previous pickup model line based on car platforms.

The most popular version of the model line is the F-150 pickup truck, currently in its fourteenth generation (introduced for the 2021 model year). From 1953 to 1983, the entry-level F-Series pickup was the 1⁄2 ton F-100. Starting in 1984, the F-150 became the entry-level. The F-150 has a long-running high-performance off-road trim level introduced for 2010, the (SVT) Raptor currently consisting of three generations. Production of the F-150 SVT Raptor ended in 2014 and it was planned to be succeeded by a new F-150 Raptor, which is based on the thirteenth and fourteenth generation F-150.

The F-Series trucks have been developed into a wide range of design configurations. Alongside medium-duty trucks and "Big Job" conventional trucks (the forerunners of the Ford L-series), the model line has been marketed as a chassis-cab truck and a panel van (a predecessor of the Ford E-Series). The F-Series has served as the platform for various full-sized Ford SUVs, including the Ford Bronco, Ford Expedition/Lincoln Navigator, and Ford Excursion. The F-Series has been marketed by its three North American brands: by Mercury as the M-Series (in Canada from 1948 to 1968), and by Lincoln in the 2000s, as the Blackwood and the later Mark LT (2010s for the latter in Mexico only).

Since 1977, the F-Series has remained the best-selling pickup truck line in the United States; it has been the best-selling vehicle overall since 1981. The F-Series has been the best-selling truck in Canada for over fifty years. As of the 2018 model year, the F-Series generated $41 billion (~$49 billion in 2023) in annual revenue for Ford. By January 2022, the F-Series models have sold over 40 million units. Currently, Ford manufactures the F-Series in four facilities in the United States.

Common 1977 Ford F150 problems

Based on the information gathered from various sources regarding common problems with the 1977 Ford F-150, here is a detailed list of issues reported by owners:

Ignition Coil Failure: Commonly reported is ignition coil failure due to excessive spark plug gap erosion, leading to a misfiring engine. This problem can be addressed by applying dielectric grease on plugs to increase longevity and prevent water damage. Replacement by a skilled mechanic is recommended to avoid further engine issues. The cost of spark plug replacement ranges from $70 to $250.

Passenger Side Head Gasket Leak: Owners have experienced oil leaks onto the starter due to a poorly assembled head gasket, leading to compromised sealing. Causes of leaks include overfilling, overheating, and gasket erosion. Solutions involve applying JB Weld bond or re-torqueing head bolts, which are cost-effective alternatives to head gasket replacement, which can be expensive, ranging from $700 to $3,500.

Power Window Malfunction: Issues with power windows not working can stem from faulty ground connections, blown fuses, low voltage, or actuator motor problems. Solutions include checking the ground connection system, ensuring proper voltage, and cleaning or replacing the actuator motor to restore window functionality.

Fuel Smell When Stopped: The smell of fuel when the vehicle is stopped may indicate a leaking oil pan gasket or severe carbon buildup in the engine. Cleaning the engine with seafoam or BG44 can help dissolve oily residues causing the issue.

Coolant Leakage into Cylinders: Coolant getting into cylinders 1 and 3 can be attributed to manifold issues, which may require inspection and repair by a qualified mechanic.

These common problems reported by owners of the 1977 Ford F-150 highlight various mechanical and electrical issues that can arise with this vehicle. Addressing these problems promptly and with the appropriate solutions can help maintain the performance and reliability of the Ford F-150 from 1977.
