Chrysler SOHC V6 engine
Encyclopedia
The single overhead cam V6 introduced in 1993 was a major advancement for Chrysler
. It was derived from Chrysler's first homegrown front-wheel drive
V6, the Chrysler 3.3 engine
, and remains in production today. The SOHC V6 is likely to be replaced by the Chrysler Pentastar engine by 2013.
There are three major variants of this basic design: the 3.5 L, 3.2 L, and 4.0 L. Additionally, a 2.7 L DOHC version
was derived. The line was expanded further for 2006 with the addition of the 4.0 L engine debuting in the Dodge Nitro
.
as well as the 3.2 L and new 4.0 L variants. All but the 2.7 and high-output 3.5 are produced at Trenton Engine
in Trenton, Michigan
.
The SOHC engine uses an engine block that is very similar to its pushrod ancestors. But the front of the block was modified for the camshaft
drive, and the heads are entirely different. One major change was that the SOHC engine was originally designed for the longitudinal placement
of the Chrysler LH platform
, rather than the transverse engine
design of the K-cars and minivans
. Since the bottom end was the same, the engine could be produced on the same assembly line in Trenton as the pushrod engine.
1993–97 3.5 L engines are a non-interference engine meaning that the valves will not collide with the pistons in the event of a timing belt failure. The 1998–2001 3.2 L, the 1998–present 3.5 L, and the 2007–present 4.0 L engines are interference designs.
At its debut in 1993, this engine produced 214 hp (160 kW) and 221 ft·lbf (300 Nm) from an iron block and aluminium cylinder heads. The 3.5 L engine was redone entirely of aluminum in 1999 as the EGG high output, producing 247–253 hp (190 kW) at 6500 rpm with 250 ft·lbf (339 Nm) of torque at 4000 rpm. Output from 2002–2004 for the standard output EGJ is 234 hp (174 kW) at 6000 rpm with 241 ft·lbf (327 Nm) of torque at 4400 rpm. Also for 2002–2004, the EGK 3.5 L Special was built exclusively for the 300M Special, producing 255 hp and 258 ft·lbf.
The EGJ was built in Trenton, MI. The EGG was built in Kenosha, WI. The EGK was discontinued in 2004.
The 3.5 L version is no longer in production as of 2011, replaced by the newer Pentastar 3.6 V6

3.5
This 3518 cc engine was a version of the 3.3 but with a larger bore of 96 mm and the important addition of overhead cams. The 3.5 L version has an intake arrangement with two separate manifolds and throttle bodies connected with a crossover valve. This provides better low and midrange torque. The four valves per cylinder are driven by a single overhead camshaft as opposed to the conventional DOHC arrangement for multivalve engines. Another difference with the 3.5 as opposed to the 3.3 is the fact that the camshaft is timed to the crankshaft with a belt rather than a chain. The water pump is also driven by the timing belt on the 3.5, whereas on the 3.3, the accessory belt drives it.At its debut in 1993, this engine produced 214 hp (160 kW) and 221 ft·lbf (300 Nm) from an iron block and aluminium cylinder heads. The 3.5 L engine was redone entirely of aluminum in 1999 as the EGG high output, producing 247–253 hp (190 kW) at 6500 rpm with 250 ft·lbf (339 Nm) of torque at 4000 rpm. Output from 2002–2004 for the standard output EGJ is 234 hp (174 kW) at 6000 rpm with 241 ft·lbf (327 Nm) of torque at 4400 rpm. Also for 2002–2004, the EGK 3.5 L Special was built exclusively for the 300M Special, producing 255 hp and 258 ft·lbf.
The EGJ was built in Trenton, MI. The EGG was built in Kenosha, WI. The EGK was discontinued in 2004.
The 3.5 L version is no longer in production as of 2011, replaced by the newer Pentastar 3.6 V6
