2006 Mustang Engine Information – 244 cubic inch V6 (4.0L Ford Cologne V6)
The Cologne V6
The 4.0 Liter (244 ci) engine used in 2005 is virtually unchanged from previous years. It uses an electronically controlled Sequential Multiport Fuel Injection system. This is the base engine for the Mustang this year. Notice…Some of the torque specifications change from year-to-year. Be sure to use the correct year’s torque specifications for your engine or you may damage the engine.
The 2005 – 2009 base Mustang was powered by Ford’s cast iron block 4.0 L Cologne SOHC V6, replacing the 3.8 L Essex OHV V6 used in 2004 and older models. It produces 210 hp (157 kW) at 5300 rpm and 240 lb·ft (325 N·m) of torque at 3500 rpm and was mated to a standard Tremec T-5 5-speed manual transmission with Ford’s 5R55S 5-speed automatic transmission available as an option.

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.
