Injection System:
Indirect Injection (IDI) via injection pump and injectors.
Cooling Method:
Water-cooled via radiator and thermostat.
Oil Type:
API CE or CF service classification diesel engine oil (Specific viscosity grade e.g., 10W-30 or 15W-40 will be in the manual).
Oil Capacity:
Approximately 3.5 - 4.0 liters (with filter change), manual will provide exact capacity.
Transmission Type:
Sliding gear type manual transmission with Hi-Lo range or similar configuration.
Gear Configuration:
