Power Delivery:
Emphasis on low-end torque, particularly for diesel engines, suitable for towing and hauling.
Diesel:
Direct Injection (DI) with mechanical injection pumps.
Petrol:
Typically Carburetor (early models) or Multi-Point Fuel Injection (MPI) (later models).
Oil Change Interval:
Typically 5,000-7,500 km for diesel, 7,500-10,000 km for petrol, or every 6-12 months. Consult specific engine recommendations.
Air Filter Replacement:
Every 15,000-30,000 km or as needed based on operating conditions.
Fuel Filter Replacement Diesel:
Crucial for diesel engines, typically every 20,000-40,000 km, or more frequently in dusty conditions.
Engine Oil Diesel:
API CH-4 or CJ-4 rated Diesel engine oil, viscosity typically 15W-40 or 10W-30 depending on climate.
Engine Oil Petrol:
API SG, SH, SJ rated Petrol engine oil, viscosity typically 10W-30 or 10W-40.
Transmission Fluid Manual:
GL-4 rated gear oil for the 5-speed manual transmission. Viscosity often 75W-90 or 80W-90.
Coolant:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Check for OEM specifications for correct type (e.g., green or orange).
Diesel Glow Plugs:
Glow plug failure can lead to hard starting in cold weather for diesel models.
Turbo Wear 4Jb1T:
Turbocharger in the 4JB1T can develop wear over time, affecting performance and oil consumption.
