⚙️ Engine Specifications
Primary Engine
Engine Options:
Primarily offered with inline-4 cylinder engines. Common variants include: 2.0L (FS-DE/FS-ZE), 2.5L (F5-DE/FS-DE - often referred to as V6 in marketing, but typically a 4-cylinder for this generation in many markets, with actual V6 being a different model designation if applicable elsewhere or in later generations). *Correction: The GF/GW 626 predominantly featured 4-cylinder engines. The V6 engine was more common in the Millenia. For the 98-02 626, the common engines were the 2.0L FS-DE and the 2.5L (which was still a 4-cylinder, sometimes designated FS-ZE or similar depending on market and tuning). The manual covers these specific engine types.*
