Production Years: 1991 - 2002
Engine: 6G72 V6
Failure Mileage Range
70,000-110,000 miles
Typical failure window
Root Cause
Original coolant temperature sensor degrades, sending incorrect cold-start fuel mixture data to ECU.
Repair Options & Estimated Costs (UK ranges)
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Sensor Replacement Minor | £180 - £320 | £95 - £180 | Replace CTS sensor, reset ECU adaptives | Fixes cold-start only; won't prevent other 6G72 failures |
Intermediate - Ignition System Refresh Intermediate | £450 - £750 | £280 - £480 | Replace CTS, distributor cap/rotor, plugs, leads | Addresses multiple 6G72 weak points; suitable if engine otherwise healthy |
Full Replacement - Rebuilt 6G72 Engine Best Value | £2,400 - £3,200 | £2,000 - £2,800 | Supply & fit rebuilt 6G72 with upgraded components, 12-month warranty | Best value for high-mileage Magnas or when bottom-end wear suspected |
Our Recommendation
Best next step for 6g72 coolant temperature sensor failure
If your Magna only struggles to start when cold and runs fine once warm, start with the sensor replacement. But if you're also experiencing misfires under load or high mileage (100k+), a rebuilt 6G72 with warranty often represents better long-term value than repeated repairs.
Don't Let Engine Failure Write Off Your Mitsubishi Magna
The Mitsubishi Magna's Australian-market engines are robust when maintained, but known failure points can lead to costly repairs. EngineMarket makes it simple to compare prices from trusted UK specialists who understand grey-import compatibility. Every rebuilt engine includes upgraded components addressing original weaknesses, backed by a 12-month unlimited mileage warranty and nationwide delivery. Compare quotes and get your imported Magna back on the road without the main dealer premium.

FAQ
Mitsubishi Magna Engine ReplacementFrequently Asked Questions
Question 1Is it worth replacing a Mitsubishi Magna engine in the UK-
Yes, if your grey-import Magna is otherwise in good condition. Rebuilt engines cost £1,800-£3,000 versus £4,000+ for a comparable replacement vehicle, making replacement economical for well-maintained imports.
- Rebuilt 6G72 engines typically cost £2,000-£2,800 supply-only
- Supply & fit adds £450-£850 depending on workshop location
- 12-month warranty protects your investment against premature failure
- Grey-import Magnas retain enthusiast value in UK classic markets
Question 2How much does a Mitsubishi Magna engine replacement cost in the UK-
Typical rebuilt engine prices range £1,800-£3,000 depending on engine code (4G54, 6G72, 6G74), with supply & fit adding £450-£850 for labour.
- 4G54 2.6L engines: £1,800-£2,400 rebuilt supply-only
- 6G72 3.0L V6 engines: £2,000-£2,800 rebuilt supply-only
- 6G74 3.5L V6 engines: £2,200-£3,000 rebuilt supply-only
- Prices exclude VAT, delivery and any ancillary parts replacement
Question 3What causes Mitsubishi Magna 6G72 engines to fail to start when cold-
The most common cause is coolant temperature sensor failure, sending incorrect data to the ECU and causing lean cold-start mixture.
- Faulty CTS triggers long crank/no-start only when engine is cold
- Replacement sensor costs £25-£60 plus 1-2 hours labour
- If misfires persist after CTS replacement, check distributor rotor
- Rebuilt engines include upgraded sensors addressing this weakness
Question 4Will a 6G72 engine from a TR Magna fit my TF Magna-
Yes, 6G72 engines are broadly interchangeable across TR-TF generations, but verify ECU compatibility and wiring harness connectors before purchase.
- Physical mounting points identical across TR-TF 6G72 applications
- ECU pinouts may differ; confirm with supplier before ordering
- Wiring harness connectors changed slightly between 1991-2000
- AWD TH/TJ models require 6G74-specific engines, not 6G72
Question 5How long does it take to fit a replacement Mitsubishi Magna engine-
Professional supply & fit typically requires 2-3 working days for straightforward 6G72 swaps, longer for AWD or Verada variants due to complexity.
- Standard RWD Magna: 2-3 days including ECU reset and road test
- AWD or Verada variants: 3-4 days due to additional drivetrain components
- Allow extra time for wiring harness adaptation on grey-import applications
- Most UK specialists offer collection/delivery to reduce owner downtime
Question 6What is the difference between Mitsubishi Magna and Verada engines-
Early Verada KR used the same 6G72 3.0L V6 as Magna TR-TF; later Verada KW used the larger 6G74 3.5L V6 not fitted to standard Magna models.
- Verada KR (1992-1996): 6G72 3.0L V6, interchangeable with Magna TR-TS
- Verada KW (1999-2003): 6G74 3.5L V6, higher output, different mounting
- 6G74 engines require specific ECU and wiring harness compatibility checks
- Verada luxury trim does not affect engine replacement pricing significantly
Question 7Can I replace a Mitsubishi Magna engine myself in the UK-
Technically possible for experienced DIYers with proper equipment, but grey-import wiring and AWD complexity make professional fitting strongly recommended.
- Requires engine hoist, transmission jack and specialist diagnostic tools
- Australian-market wiring may differ from UK-spec Mitsubishi vehicles
- ECU adaptation and immobiliser pairing often require dealer-level equipment
- Professional fitting preserves warranty coverage on rebuilt engines
Question 8Do Mitsubishi Magna replacement engines come with a warranty-
Yes, all engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty from vetted UK specialists.
- Warranty covers internal components against manufacturing defects
- Labour for warranty claims typically not included; confirm terms upfront
- Keep service records and oil change receipts to maintain warranty validity
- Some suppliers offer extended warranty options for additional cost
Question 9How do I identify which engine code my Mitsubishi Magna has-
Check the engine identification plate on the firewall or strut tower, or decode your VIN; common codes are 4G54, 6G72, or 6G74.
- Engine code stamped on block near cylinder head on driver's side
- VIN decoding: 10th character indicates model year, engine code in positions 4-6
- Registration lookup via DVLA may not specify Australian-market engine codes
- When in doubt, provide photos of engine bay to supplier for verification
Question 10Where can I find a Mitsubishi Magna engine specialist in the UK-
EngineMarket connects you with vetted UK specialists experienced in grey-import Australian vehicles, including Magna and Verada applications.
- Not all UK engine rebuilders stock Australian-market engine components
- Specialists familiar with 6G72/6G74 wiring and ECU systems reduce fitment risk
- Compare multiple quotes to balance price, warranty terms and turnaround time
- Phone consultation recommended for complex AWD or Verada applications
