The Chrysler EGN 3.5-liter V6 petrol engine was produced in the USA from 2003 to 2006 and was installed only in the pre-facelift version of the popular US Pacifica model. The power unit was equipped with a variable geometry intake manifold and an EGR valve.
The LH series also includes internal combustion engines: EER, EGW, EGE, EGG, EGF, EGS and EGQ.
The V6 EGN is one of Chrysler’s 3.5-liter V6 engines, of which there are about 10 versions. Structurally, the engines strongly resemble each other, and together they are built on the basis of a cast-iron block of a 3.3-liter engine. They increased the diameter of the cylinder, raised the compression ratio and made other innovations.
The engine was installed on:
- Chrysler Pacifica 1 (CS) in 2003 – 2006.

Disadvantages of the EGN engine
- This unit is known for frequent overheating and slagging of oil channels;
- Lack of lubrication contributes to the rapid wear of the liners and then the motor jamming;
- Also, the speed regularly floats here due to contamination of the throttle and the EGR valve;
- Often there are antifreeze leaks from under the pump gasket or heater tube;
- Exhaust valves become carbonized and eventually fail to close tightly.
