Ford's 4.0L (V6) engines

Ford’s 4.0L is a V6 engine that’s part of the Cologne family of engines, and is designed for use in Ford’s SUVs and pickup trucks.

The base engine consists of:

• Cast iron engine block and aluminum cylinder head
• Single Overhead Camshaft (SOHC)
• Jackshaft timing chain
• Sequential multi-port fuel injection

Engine specifications include:

• A displacement of 245 cubic inches (4,015 cubic centimeters)
• 3.94 in x 3.31 in (100 mm x 84 mm) cylinder bore and piston stroke
• 9.0:1 compression ratio
• 207 to 216 horsepower (154 to 161 kW) at 5,250 rpm 
• 238 to 254 lb-ft (323 to 344 Nm) of torque at 3,000 rpm

The Ford 4.0L was used in some Ford applications, including the Ranger, Explorer, and Mustang—it was also used in the Mazda B-Series, Mercury Mountaineer, and Land Rover Discovery.

Some of these early SOHC engines were known for timing chain rattle issues, but were eventually mitigated in later years by modifications to the design of the engine timing chain system.

Overall, the Ford 4.0L is a powerful engine, capable of providing many years of reliable, trouble-free operation when properly maintained.
