What engine is in the 1979 Toyota FJ40?
The 1979 FJ40’s standard engine was Toyota’s 4.2-liter inline-six petrol engine, the 2F. In some export markets, a 4.0-liter diesel inline-six (the 2H) was offered as an alternative.
The standard petrol engine: the 2F
The 2F is the emblematic powerplant associated with late‑’70s FJ40s. It is a carbureted, inline-six 4.2-liter engine designed to deliver steady low‑end torque for off‑road work and reliable everyday performance for the era.
Key characteristics of the 2F include:
- Inline-six configuration with a traditional pushrod (OHV) valvetrain
- Displacement: 4.2 liters (4169 cc)
- Fuel system: carbureted
- Output: typically around 135 horsepower and roughly 230–250 lb-ft of torque
In 1979, US-market FJ40s were most commonly equipped with the 2F engine, usually paired with a four-speed manual transmission and a rugged transfer case. Emissions controls and regional variations could influence exact figures.
Market variations: diesel options and other notes
Beyond the 2F petrol engine, some export markets offered diesel powertrains for longer-range and tougher-duty use. The diesel option most commonly found in those markets was the 2H, a 4.0-liter inline-six diesel.

Diesel FJ40s are much less common in the United States, but were popular in Africa, parts of Europe, and other regions where diesel power and fuel economy were prioritized.
How to verify your FJ40’s engine
To confirm the exact engine in a given 1979 FJ40, check the engine code stamped on the engine block and cross‑reference it with the vehicle’s VIN and market documentation. This helps distinguish between the 2F petrol engine and any diesel alternatives like the 2H.
Where to look and what to check
Typical locations for engine codes include the block near the starter, the valve cover, or a boss on the front of the block. The VIN may encode market information that correlates with the engine option. If you’re unsure, consult a Toyota parts catalog or a qualified technician.
Visual cues can also help: carbureted intake and absence of glow plugs point toward petrol 2F, while diesel FJ40s show diesel fuel systems and related components.
Summary
The 1979 FJ40 most often ran a 4.2-liter inline-six petrol engine, the 2F, known for its durability and usable low-end torque. In some export markets, a 4.0-liter diesel, the 2H, was offered as an alternative. Verifying the exact engine for a specific vehicle involves checking the engine block code, VIN, and market documentation.
What kind of engine is in the FJ40?
3.9-liter inline six-cylinder engine
One of the most common and iconic engines found in the FJ40 is the 3.9-liter inline six-cylinder engine. This engine, known as the “F” engine, was part of Toyota's “F series” of engines and featured a cast-iron block and cylinder head.

What year is FJ40 the best?
The "best" year for an FJ40 depends on your priorities, but many enthusiasts favor late-model years like 1976–1984 due to improvements like front disc brakes and the 4-speed transmission. Other models have unique appeals, such as 1975 being the last year for the classic tailgate in the US, while early years offer a more basic and purist experience.

Popular late-model years (1976–1984)
- Improved features: These years often include front disc brakes (standard in 1976), a larger 2F engine (vs. the older F engine), and a 4-speed transmission.
- Rear doors: The 1975 model year introduced rear ambulance doors in the US market, which many prefer over the older tailgate.
- Other upgrades: Models from 1977 and later may have features like rear flip-out wing windows, and 1979 and later models had the option for power steering and A/C.
Early and mid-model years (Pre-1976)
- Simpler design: These years offer a more basic, purist experience with 3-speed transmissions and drum brakes.
- Classic look: Early models have a classic look with a front bench seat and a 1F engine.
- Parts availability: Some parts may be harder to find for very early models.

Other considerations
- Engine: The later 2F engine is generally more powerful than the earlier F engine.
- Emissions: In states with strict emissions testing (like California), an earlier model (before 1975) may be easier to pass without modifications, as some later models are subject to testing.
- Daily driving: If you plan on using the vehicle for daily driving, later models with disc brakes and power steering (if equipped) are more practical.
