Cooling Method:
Water-cooled, pressurized system with thermostat and fan.
Oil Capacity:
Approximately 7.5 - 8.0 Liters (check manual for exact specification).
Oil Type Recommendation:
API CD/CE/CF or higher, SAE 15W-40 or 10W-30 depending on climate (refer to manual).
Wheelbase:
Varies significantly by Canter model (e.g., 2,500 mm to 3,400 mm+).
Gross Vehicle Weight Rating:
Varies by configuration, typically from 3.5 to 7.5 tons GVWR or higher.
Curb Weight:
Highly variable based on chassis and body style.
Crash Test Results:
As a commercial vehicle, specific NHTSA/Euro NCAP ratings may not always be directly comparable to passenger cars, but structural integrity for cargo and driver protection is paramount.
Brake System:
Hydraulic braking system with disc front and drum rear common. ABS may be optional or standard on later models.
Occupant Protection:
Reinforced cabin structure, seatbelts, energy-absorbing materials.
Features:
Generally basic for commercial vehicles of its era; typically AM/FM radio, potentially CD player. Focus is on function over advanced features.
Features:
Limited by era. May include power steering, basic anti-lock braking systems (ABS) on later models or higher trims. Driver comfort features are secondary to utility.
Features:
No modern smartphone integration or advanced telematics expected for this engine and era.
Engine Oil Filter Change:
Typically every 5,000-10,000 km or 6-12 months, depending on operating conditions and oil quality (refer to manual for exact interval).
Air Filter Replacement:
Every 10,000-20,000 km or as needed, more frequently in dusty environments.
Fuel Filter Replacement:
Typically every 20,000-40,000 km.
Coolant Type:
Ethylene glycol-based coolant (e.g., Mopar OAT or HOAT compatible, check manual for specific color/type).
Brake Fluid Type:
DOT 3 or DOT 4 (check manual for specific requirement).
Common Problems:
Potential issues can include turbocharger wear, injector pump calibration, glow plug failures, and cylinder head gasket leaks under extreme heat or age. Regular maintenance is key to longevity.
Prevention Strategies:
Adhering to strict oil change intervals, allowing engine warm-up and cool-down cycles, and using high-quality fuel and filters are crucial.
Manufacturer:
Mitsubishi Fuso Truck and Bus Corporation (a subsidiary of Daimler Truck AG as of recent years, historically part of Mitsubishi Group).
Canter Lineage:
The Mitsubishi Canter is a long-standing and globally recognized series of light-duty trucks, dating back to the 1960s. The 4M40 engine was a prominent powerplant in various generations.
