2005 Mustang Engine Information – 244 cubic inch V6 (4.0L Ford Cologne V6)

The Cologne V6

The base Mustang did away with the wheezy 3.8-litre overhead valve V-6 in favor of Ford’s more powerful and freer revving 4.0-litre single overhead cam “Cologne” V-6 that had been introduced in the Ford Explorer in 1997. This new engine used a 60-degree cast iron block with a 3.94-inch bore and 3.3-inch stroke. This overhead cam engine was based on the rugged 4.0-litre “Cologne” overhead valve V-6 and therefore shared the same engine block.

Ford used a clever timing chain system to drive the camshafts in each cylinder head. A jackshaft was installed in place of where the cam resided in the overhead valve version of the engine. This jackshaft was used to drive the camshafts in the left and right cylinder heads. The timing chain for the left bank was located in the front of the engine while the chain driving the right side cam was located at the rear of the engine and a third chain at the front of the engine connected the jackshaft the crankshaft.

For Mustang duty the V-6 was treated to a unique camshaft grind, tuned exhaust manifolds, new flywheel and oil pan. Topping of the V-6 was a variable intake manifold and an electronic drive-by-wire throttle control; giving the V-6 excellent response as well as great power and flexibility over the entire rev range. In the Mustang, the V-6 produced a healthy 210-horsepower and 240 pound-feet of torque, enough power to nearly match the output of the V-8 Mustang GT from 10 years earlier!

While the 2005 Mustang V-6 didn’t sound as sultry as a V-8 powered Mustang it did have very respectable performance capable of pushing the car to 60 miles an hour in less than seven seconds. It was also a big improvement in the area of refinement, running smoother and quieter than any six-cylinder Mustang in recent memory. For the first time in the car’s history a Mustang with the base engine was no longer a wheezy, unrefined, underpowered penalty box of a car to drive, it was actually a viable alternative to the V-8 for people who didn’t need or want the V-8 but still wanted a fun car that was smooth and had some kick.

Engine & Other Torque Specifications

All torque specifications provided in this table are those recommended by FORD. If you use special bolts, follow the torque specifications provided by the manufacturer. I recommend that you use the 3 step torque technique where you torque down the bolts in three equal steps. Once you have reached the maximum recommended torque setting, go around one more time. Do not torque in a circular pattern. Always torque cross to cross.
