Engine Specifications
|
|
Primary Engine
|
|
Engine Code Petrol:
|
6G72 (3.0L V6 SOHC MPI).
|
|
Engine Code Diesel:
|
4D56 (2.5L SOHC DI-D Common Rail Turbo Diesel).
|
|
Performance Diesel
|
|
Horsepower 4D56 Hp:
|
Approximately 134 hp to 175 hp, depending on turbocharger specification and engine variant.
|
|
Torque 4D56 Nm:
|
Approximately 314 Nm to 400 Nm, depending on turbocharger specification and engine variant.
|
|
Performance Petrol
|
|
Horsepower 6G72 Hp:
|
Approximately 175-180 hp.
|
|
Torque 6G72 Nm:
|
Approximately 255-260 Nm.
|
|
Fuel System
|
|
Diesel Fuel System:
|
Common Rail Direct Injection (CRDI) with turbocharging and intercooler. Common fuel filter part number: MD628053 or equivalent.
|
|
Petrol Fuel System:
|
Multi-Point Fuel Injection (MPI).
|
|
Cooling System
|
|
Coolant Type:
|
Mitsubishi Dia Queen Super Long Life Coolant (SLLC) or equivalent, typically a 50/50 mix of ethylene glycol and deionized water. Check specific manual for factory part number.
|
|
Lubrication System
|
|
Engine Oil Spec 4D56:
|
API CI-4 or CH-4 specification diesel engine oil, SAE 10W-30 or 15W-40 depending on ambient temperature. Consult manual for precise viscosity. Oil filter part number: MZ690072 or equivalent.
|
|
Engine Oil Capacity 4D56:
|
Approximately 6.8 - 7.5 liters (including filter), depending on specific engine variant and oil pan.
|
|
Maintenance
|
|
Service Intervals
|
|
Oil Change Interval Km:
|
Typically every 10,000 km or 12 months, whichever comes first, for diesel engines. Petrol engines may have similar or slightly shorter intervals. Always consult the manual for the specific recommendation.
|
|
Air Filter Replacement Km:
|
Every 20,000 - 40,000 km or as needed based on operating conditions (dusty environments require more frequent checks).
|
|
Fuel Filter Replacement Km:
|
For diesel: Every 40,000 - 60,000 km. For petrol, spark plug replacement every 60,000 - 100,000 km.
|
|
Timing Belt Replacement Km:
|
If equipped with a timing belt (less common on 4D56 diesel which often uses a chain or a belt on a different system), intervals are typically 100,000 - 120,000 km. The 4D56 DI-D typically uses a timing chain or a belt driving the camshafts which is generally more robust than a timing belt on petrol engines.
|
|
Fluid Specifications
|
|
Brake Fluid Spec:
|
DOT 3 or DOT 4. Consult the manual for the specific recommendation and replacement interval.
|
|
Power Steering Fluid Spec:
|
Dexron II/III or equivalent ATF. Consult manual for exact specification.
|
|
Known Issues
|
|
Common Issues Diesel:
|
Injectors can be sensitive to fuel quality, turbocharger issues (VGT control), EGR valve clogging, glow plug failure, potential for swirl flap issues in some intake manifolds, DPF regeneration problems on later models if not used for their intended purpose.
|
|
Common Issues General:
|
Suspension wear (bushings, ball joints) from heavy use or off-road driving, clutch wear on manual transmissions, rust/corrosion on the chassis and body in harsh climates, starter motor failure, occasional electrical gremlins, rear leaf spring fatigue.
