The Mitsubishi 380's sole 6G75 3.8L V6 petrol engine is generally robust when maintained, but timing belt neglect, oil leaks and idle control issues drive most UK replacement enquiries. Every rebuilt 6G75 engine supplied through EngineMarket includes upgraded seals, bearings and timing components designed to address original failure points - plus a minimum...
Timing Belt Failure
Most affected vehicles
Mitsubishi 380 ES, LS, LX, SX, VRX, GT (2005-2008, 6G75, 6G75-1)
Failure mileage range
60,000-100,000 miles if not replaced preventatively
Typical failure window
Root cause
The 6G75 is an interference engine - if the timing belt snaps or jumps teeth, pistons strike valves causing bent valves, damaged pistons and potential head damage.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Timing Belt Service | £450 - £750 | £300 - £500 | Replace timing belt, tensioner, idlers, water pump; set timing marks | 60k mile interval; only viable before belt failure occurs |
| Full Replacement - Rebuilt 6G75 Engine | £3,500 - £5,500 | £2,100 - £3,200 | Supply & fit rebuilt engine with upgraded timing components, bench tested, 12-month warranty | Restores like-new reliability; only option after catastrophic belt failure |
Our recommendation
On a Mitsubishi 380 worth £3,000-£8,000, preventative timing belt service at 60k miles is far cheaper than engine replacement. If the belt has already failed, a rebuilt 6G75 with upgraded components is the only reliable solution.
