Mitsubishi L100 Replacement Engines

The Mitsubishi L100 evolved through multiple generations from 1987-2007 with consistent engine families across variants. The early L100 used 1.6L 4G32 petrol engines, followed by the robust 4G63 2.0L petrol and 4D68 2.3L diesel powerplants. All 4G63 engines suffered timing chain tensioner failures around 120,000 miles, while 4D68 diesels experienced common rail wear and injector issues after 150,000 miles. The L100's simple, durable design means replacement engines can address these known failure points with updated components for improved longevity.

Mitsubishi L100 Models & Engines Codes

The L100 series utilized several engine families across its production life, with shared components and common failure patterns regardless of trim level.

  • 4G32: 1.6L petrol (H10A chassis, 1987-1996) - Simple OHV design with minimal common issues
  • 4G63: 2.0L petrol (H11A/H12A chassis, 1996-2007) - Timing chain tensioner (MB062044) failure at 120,000 miles
  • 4D68: 2.3L diesel (H11A/H12A chassis, 1996-2007) - Injector and common rail wear after 150,000 miles
