Mitsubishi Maven Engine ReplacementCompare Prices & Save

The 4G15 is generally robust when maintained, but timing chain tensioner wear and oil consumption are common on high-mileage imported examples. Rebuilt units with upgraded components offer the best long-term reliability for UK owners.

• Timing chain tensioner (OEM MB802600) requires attention at 80k-120k miles
• Oil consumption increases after 100k miles due to piston ring wear
• Valve train noise from lash adjusters is common but rarely catastrophic
• Rebuilt engines with upgraded parts significantly improve longevity

Rebuilt 4G15 engines for the Maven typically cost £1,700-£2,100 supply-only in the UK, with supply & fit adding £400-£700 depending on location and workshop.

• Reconditioned units start from £1,700 with 12-month warranty
• Used engines are cheaper (£1,200-£1,600) but carry unknown history
• Supply & fit labour adds £400-£700 depending on region
• Import-experienced specialists may charge a premium for rare vehicle expertise

Specialist import workshops and engine rebuilders familiar with the Colt T120SS-sourced 4G15 are your best option; EngineMarket connects you with vetted UK suppliers experienced with Indonesian imports.

• Generalist breakers rarely stock Maven-specific 4G15 units
• Import specialists understand ECU calibration and documentation needs
• Rebuilt engines from UK specialists include warranty and support
• EngineMarket's comparison tool sources quotes from multiple vetted suppliers

No - while the Maven shares bodywork with the Suzuki APV, it uses the Mitsubishi-sourced 4G15 engine from the Colt T120SS, which is not interchangeable with APV engines.

• Maven exclusively uses the Mitsubishi 4G15 SOHC MPI petrol engine
• APV engines have different mounting points and ECU calibration
• Cross-referencing parts requires Colt T120SS donor knowledge
• Using the wrong engine can cause fitment and registration issues

With proper maintenance, the 4G15 can reach 150,000+ miles, but timing chain tensioner wear and oil consumption often drive replacement enquiries between 80k-120k miles on imported examples.

• Regular oil changes with correct viscosity extend engine life
• Timing chain tensioner should be inspected/preventatively replaced at 80k miles
• High-mileage units often develop oil consumption from ring wear
• Rebuilt engines with upgraded components can exceed original lifespan

Yes, but import costs, documentation, and compatibility checks make UK-sourced rebuilt engines from import-specialist suppliers a more practical and warranty-backed option for most owners.

• Import duties, shipping and VAT add significant cost to Indonesian-sourced engines
• UK suppliers handle compliance documentation for registration
• Rebuilt UK units include warranty and post-fit support
• Lead times for imports can delay repairs by weeks or months

Timing chain tensioner wear (OEM part MB802600) is the most frequently reported issue, causing cold-start rattle and potential chain jump if neglected on high-mileage imported examples.

• Tensioner loses hydraulic pressure after 80k-120k miles
• Rattle on cold start is the primary warning symptom
• Preventative replacement is far cheaper than repairing valve damage
• Rebuilt engines include upgraded tensioners as standard

The 4G15 engine code is stamped on the block near the oil filter housing; your V5C registration document and DVLA check via EngineMarket also confirm the exact code for ordering parts.

• Engine stamp location: block side, near oil filter
• V5C document lists engine capacity and fuel type
• DVLA lookup via EngineMarket verifies exact 4G15 variant
• Colt T120SS donor reference helps cross-check parts compatibility

Yes, both GLX and GLS trims were available with a 4-speed automatic; the 4G15 engine is identical to manual variants, so replacement engines are fully compatible with automatic Mavens.

• Automatic and manual Mavens share the same 4G15 engine block
• ECU calibration differs slightly; confirm variant when ordering
• Rebuilt engines are supplied ready for either transmission type
• Supply & fit specialists can handle automatic-specific commissioning

Rebuilt 4G15 engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty from UK specialists, covering parts and labour for fitment-related issues.

• 12-month warranty is standard across EngineMarket's network
• Unlimited mileage coverage protects high-use imported vehicles
• Warranty terms vary slightly by supplier; confirm before ordering
• Documentation provided for UK registration and insurance purposes
