Mitsubishi I Replacement Engines
The Mitsubishi I evolved through two critical generations: the original A00V (2006-2012) featuring 659cc 3-cylinder engines, and the second generation (2012-present) with upgraded 659cc and 799cc powertrains. All early I models suffered from timing chain tensioner failures addressed in Service Bulletin EN-09-001, while later variants share oil pump drive gear vulnerabilities regardless of trim level. The I series adopted Mitsubishi's global platform strategy with shared engine management systems across kei-car variants, though cooling system designs remained consistent throughout both generations. Common issues include water pump seal degradation and ECU relay failures affecting all I variants from 2006 onwards.
Mitsubishi I Models & Engines Codes
The I series utilizes three primary engine families across its production timeline, with shared components and common failure patterns affecting multiple variants simultaneously.
- 3A90: 659cc 3-cylinder (A00V, 2006-2012) - Timing chain tensioner (MR326512) failure across all variants
- 3A92: 659cc 3-cylinder DOHC (A00V/A01V, 2012-present) - Water pump seals (MR196543) common failure point
- 3A93: 799cc 3-cylinder (A01V, 2013-present) - Oil pump drive gear (MR327891) issues in all power outputs
- 3A91: 659cc 3-cylinder SOHC (A00V, 2006-2012) - ECU relay (MR284756) failures affecting entire generation
All I series engines share identical cooling system architecture and mounting points, allowing for cross-generational compatibility in many service applications. The compact 3-cylinder design was engineered with space efficiency in mind while maintaining Mitsubishi's reliability standards across the kei-car segment.
Buy Used and Second-Hand Mitsubishi I Engines
For I series owners: Used engines carry high risk due to shared timing chain and water pump failure patterns across all variants. Reconditioned units with updated tensioners (MR326512) are essential for pre-2012 models. Remanufactured 3A92 engines with upgraded water pump seals (MR196543) are recommended for current generation variants regardless of trim level.
- Reconditioned 3A90 engines with timing chain upgrades
- Remanufactured 3A92 units with improved cooling components
- Complete 3A93 engines with oil pump modifications
- Core exchange programs for any I series engine
All engines undergo comprehensive inspection and testing to ensure compatibility with the I series platform, maintaining Mitsubishi's engineering specifications and performance standards.
