Mitsubishi Outlander 2.0 (4B11) Engine ReplacementCompare Prices & Get Quotes

A used 4B11 engine typically costs £900-£1,500 supply-only, while a reconditioned unit runs £1,500-£2,800 and a full rebuilt engine £2,500-£3,200. Add 8-10 hours of labour at around £65/hr for indie specialist fitting - around £520-£650 - or more at main dealer rates.

• Used 4B11: cheapest option, 30-60 day warranty typical
• Reconditioned 4B11: mid-range, tested and worn components replaced
• Rebuilt 4B11: full strip and rebuild, 12-month warranty, upgraded components

Common warning signs include a cold-start rattle from the timing chain area, loss of power or engine stall from drive belt detachment (especially if the belt tensioner recall SR-18-001 hasn't been completed), and excessive oil consumption.

• Cold-start rattle -> timing chain tensioner or guide wear
• Battery discharge warning + loss of power steering -> belt tensioner failure
• Engine warning light -> investigate with diagnostic scan

A typical Outlander 2.0 4B11 from 2009-2018 is worth £5,000-£14,000, so a rebuilt engine at £2,500-£3,200 plus fitting often represents good value - around 30-50% of vehicle value. For pre-2012 Outlander 2.0 examples worth under £5,000, consider used engine options or evaluate scrap value.

• Mid-range Outlander 2.0 (£6k-£10k): rebuilt engine is sensible if keeping the car 2+ years
• Lower-value Outlander 2.0 (under £5k): used engine or repair typically makes more sense
• High-value Outlander 2.0 (£12k+): replacement cost is small relative to value

The 4B11 engine uses a timing chain, not a belt. That means no scheduled timing belt replacement interval - the chain is designed to last the life of the engine under normal conditions with proper oil maintenance .

• No timing belt replacement required on Outlander 2.0 4B11
• Keep up oil changes - chain, guides and tensioner rely on good lubrication
• Listen for cold-start rattle; that's the primary timing chain warning sign

Both are from the same 4B1 engine family, sharing a timing chain design and MIVEC variable valve timing. The 4B12 is a 2.4L version (2,360cc) producing approximately 170bhp, while the 4B11 is 2.0L (1,997cc) at 148-150bhp. The 4B12 was offered in some markets as a higher-output petrol option but was less common in UK Outlander sales than the 4B11.

• 4B11: 2.0L, 148-150bhp, UK core petrol variant
• 4B12: 2.4L, ~170bhp, rarer in UK Outlander
• Both share MIVEC, timing chain, similar reliability profile
