Mitsubishi Colt Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Mitsubishi Colt replacement engines. Whether battling 4G1 engine failures across early C12/C15 Colts or 1.5L MIVEC issues in later CZ4 models, we provide direct OEM-spec solutions for the entire Colt series.
Mitsubishi Colt Replacement Engines
The Mitsubishi Colt evolved through three critical generations: C12/C15 (2004-2012) with 4G1 and 4A9 engines, followed by the CZ4 generation (2012-2017) introducing the 1.5L MIVEC family. All 4G1 engines (C12/C15) suffered timing belt tensioner failures addressed in Service Bulletin M18-04 across all variants, while CZ4 MIVEC engines share oil pump weaknesses regardless of trim level. The later generations adopted more robust MIVEC technology but inherited EGR cooler vulnerabilities from predecessors, affecting both 1.5L petrol and 1.6L diesel variants uniformly.
Mitsubishi Colt Models & Engines Codes
Engine families across Colt generations share common components and failure patterns, making family-wide understanding crucial for proper replacement decisions.
- 4G13/4G15: 1.3L/1.5L petrol (C12/C15, 2004-2012) - Timing belt tensioner (MB991931) failure across all variants
- 4A91: 1.5L petrol (C15/CZ4, 2009-2017) - Oil pump (1510A007) weakness in all power outputs
- 4N14: 1.6L diesel (CZ4, 2012-2017) - EGR cooler (MD630968) cracking in all trim levels
- 4G93: 2.0L petrol (C15, 2006-2012) - Head gasket (MB991621) failure affecting all 2.0L variants
These engine families span multiple Colt body styles including saloon, estate, and hatchback variants, with identical core components regardless of body configuration. All engines share common mounting points and electrical connections within their respective generations.
Buy Used and Second-Hand Mitsubishi Colt Engines
