Mitsubishi Galant Engine ReplacementReconditioned & Used Prices Compared

The Mitsubishi Galant used several petrol engines across its UK production run, primarily the 4G63 inline-four and 6A13 V6 families. Compatibility depends on generation, chassis code and variant.

• 4G63 fits GLS, GLXi and VR-4 variants (1983-2004)
• 6A13 V6 powers Elegance and Sport trims (1996-2004)
• Engine mounts and ECU differ between Mk V-VIII generations
• Always verify chassis code (E10/E30/E50/EA) before ordering

Rebuilt Mitsubishi Galant engines typically range from £750 to £3,800 depending on engine code, with 4G63 and 6A13 at the lower end and VR-4 turbo units commanding premium pricing.

• 4G63 rebuilt: £750-£1,800 supply only
• 6A13 V6 rebuilt: £800-£2,400 supply only
• 6A13TT VR-4 rebuilt: £1,500-£3,800 supply only
• Supply & fit adds £400-£900 labour depending on location

The 4G63 is robust when maintained, but 7-bolt VR-4 versions suffer crankwalk failure between 60k-90k miles without upgraded thrust bearings.

• Crankwalk causes clutch pedal sticking and eventual seizure
• Preventative short block rebuild costs £1,100-£2,100 specialist
• Rebuilt 4G63T with forged components eliminates crankwalk risk
• Regular oil changes with quality synthetic reduce bearing wear

Timing belt tensioner wear is the most common cause of noise on 6A13 engines; replace belt and tensioner at 60k miles to prevent interference engine damage.

• 6A13 is interference design; belt failure bends valves
• Tensioner replacement costs £280-£450 specialist labour
• Full belt kit with water pump recommended at same interval
• Ignoring noise risks £2,000+ cylinder head repair costs

While mechanically possible, Galant engine replacement requires specialist tools and knowledge of AWD/AYC systems on VR-4 models; professional supply & fit is recommended.

• VR-4 AYC differential needs calibration after engine removal
• Engine hoist and transmission jack essential for safe removal
• ECU coding may be required for GDI and V6 variants
• Professional fit includes warranty on labour and components

Yes, every engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty from vetted UK specialists, with extended options available.

• Warranty covers parts and labour for manufacturing defects
• Claim process handled directly with supplying specialist
• Keep service records to maintain warranty validity
• Extended 24-month warranties available on remanufactured units

Carbon build-up on intake valves is the primary cause of misfire on 4G93 GDI engines; walnut blasting cleaning restores performance every 30k miles.

• Direct injection sprays fuel into cylinder only, not valves
• Carbon deposits restrict airflow causing rough idle and power loss
• Walnut blasting costs £180-£320 specialist labour
• Preventative fuel system cleaner additives offer limited benefit

With proper maintenance, Galant engines regularly exceed 150,000 miles; timing belt adherence and oil quality are the biggest factors in longevity.

• 4G63 and 6A13 can reach 200k miles with preventative care
• Timing belt replacement at 60k miles prevents catastrophic failure
• Synthetic oil changes every 5k-7k miles reduce wear significantly
• Address minor leaks early to avoid secondary damage

• Warranty protection reduces long-term ownership risk
• Supply & fit bundles labour for predictable total cost
• Consider sentimental value and known service history
