The availability of an official English-language service manual for the C24 is very limited. The best and most comprehensive resource is widely recognized to be a Russian-language manual available online:
For quick reference during routine servicing, the factory manual highlights these critical torque values and fluid capacities: Component / Fastener Specification / Torque Value 3.9 Liters (with filter change) Cylinder Head Bolts (QR20DE) Multi-step process ending at 75 Nm (55 lb-ft) Spark Plug Torque 20–25 Nm (15–18 lb-ft) Front Wheel Lug Nuts 108 Nm (80 lb-ft) CVT Fluid Capacity (Total) Approx. 8.1 Liters Suspension, Steering, and Brakes
Ensure the manual covers your specific engine layout (QR20DE petrol vs. YD25DDTi diesel), as wiring systems differ significantly.
