Chrysler SOHC V6 engine


The single overhead cam V6 engine 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. The SOHC V6 has been replaced by the Chrysler Pentastar engine.
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.

History

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 1998–2010 3.5 L, and the 2007–2011 4.0 L engines are interference designs.

3.5

This engine was a version of the 3.3 but with a larger bore of and the important addition of overhead cams. The 3.5L version has an intake arrangement with two separate manifolds and throttle bodies connected with a crossover valve. This provides better low and midrange torque. Another difference with the 3.5 as opposed to the 3.3 is that it has a timing belt, not a timing 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 and 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 at 6500 rpm with of torque at 4000 rpm. Output from 2002–2004 for the standard output EGJ is at 6000 rpm with of torque at 4400 rpm. Also for 2002–2004, the EGK 3.5 L Special was built exclusively for the 300M Special, producing and. The EGK was discontinued in 2004.
The 3.5 L variant is no longer in production as of 2011, replaced by the newer Pentastar 3.6 V6.
The 3.2 L version came along with the updated LH platform in 1998. It was an SOHC 4-valve design displacing with a smaller bore but the same stroke as the 3.5. It produced and and met the TLEV standard. It was discontinued after the 2001 model year.
Applications:
The 3.5 L engine was expanded to for the 2007 Dodge Nitro and Chrysler Pacifica. Like its family members, this is a SOHC engine and is built in Trenton, Michigan. DaimlerChrysler reportedly spent $155 million to expand the Trenton plant to manufacture this engine.
Applications:
The DOHC 2.7 L Chrysler LH engine is based on this same design, though the bore, stroke, and production site are different.
