The Grand Cherokee SUV and, for a brief period, Ram or Dakota pickups were equipped with the 4.7-liter V8 Jeep EVC or PowerTech High Output engine, which was manufactured between 2002 and 2008. In addition to having more power than its equivalent, the motor had a knock sensor.
The EKG, EVA, and EVE internal combustion engines are also part of the PowerTech series.
The engine was mounted 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 needs particular oils to avoid clogging its small oil passageways;
Additionally, hydraulic lifters frequently stick here as a result of improper lubricant selection;
Periodically, but much less frequently, valve seats are lost;
Three chains with a 200,000 km resource make up timing; however, your primary costs will be related to excessively high fuel consumption.
