The 4.7-liter V8 Jeep EVC or PowerTech High Output engine was assembled from 2002 to 2008 and was installed on the Grand Cherokee SUV and for a very short time on Ram or Dakota pickups. The motor differed from its counterpart not only in greater power, but also in the presence of a knock sensor.
The PowerTech series also includes internal combustion engines: EKG, EVA and EVE.
The engine was installed on:
- Dodge Dakota 3 (ND) in 2007 – 2008;
- Dodge Ram 3 (DT) in 2007 – 2008;
- Jeep Grand Cherokee 2 (WJ) in 2002 – 2004;
- Jeep Grand Cherokee 3 (WK) in 2007 – 2008.

Disadvantages of the EVC engine
- The engine requires specific oils or its narrow oil passages will become clogged;
- Also, due to the wrong choice of lubricant, hydraulic lifters often stick here;
- Significantly less often, but periodically there is a loss of valve seats;
- Timing consists of three chains with a resource of 200 thousand km;
- But your main expenses will be associated with excessively high fuel consumption.
