Mitsubishi Xpander Replacement Engines
Launched in 2017 on the GA platform, the Xpander series has relied on Mitsubishi’s 4A9x and 4N1x engine families across all trims-from GLX to Cross S-AWC. Early models (2017-2019) used the 4A90/3A92/4A91 trio, while post-2020 variants introduced diesel options (4N13/4N14) and MIVEC-enhanced petrol units. Mitsubishi Technical Bulletin MT-2018-07 identified premature cam wear in early 4A9x engines, affecting all GA-chassis Xpander MPVs regardless of trim or drivetrain.
Mitsubishi Xpander Models & Engines Codes
All Xpander variants share the GA chassis and compatible powertrain mounts, enabling cross-variant engine swaps when codes align. Key engine families include:
- 4A91 (1.5L petrol): Standard across GLX, GLS, Exceed, Sport (2017-Present)
- 4A91 MIVEC/S-AWC: Enhanced variants in Ultimate, Cross, All-Terrain (2019-Present)
- 4N14 (1.8L diesel): Diesel GL/Exceed for EU/UK markets (2020-Present)
- 4N13 (1.5L diesel): Short-run Eco Diesel & Fleet models (2018-2020)
- 3A92/4A92 (1.6L): Early GLS and limited HEV prototypes (2017-2023)
- 4A90 (1.3L): Commercial Budget Van/LWB (2017-2019)
Despite power or trim differences, all GA-platform Xpander engines share common failure points-particularly timing chain tensioner wear (OEM MB524273) in petrol units and EGR cooler cracking in diesels.
Buy Used and Second-Hand Mitsubishi Xpander Engines
Used Xpander engines often carry hidden wear due to shared design flaws across the GA series. For reliable long-term performance, reconditioned units are strongly recommended-especially for 4A91/4A90 petrol engines prone to oil starvation and 4N13/4N14 diesels with carbon-laden injectors.
- Reconditioned: Fully rebuilt with OEM-spec parts, ideal for all GA variants
- Remanufactured: Precision-machined block/head, recommended for high-mileage fleet use
- Used (as-is): High risk-only suitable with full service history and compression test
Every rebuilt engine we source includes upgraded components addressing known Xpander series-wide weaknesses, ensuring consistent reliability across GLX through Cross S-AWC trims.
