Technical Reference and Fluid Data

Understanding factory workshop documentation requires access to verified specifications. Engine oil capacity for periodic changes is documented at 1.20 L, utilizing a recommended grade of API service SG or higher with JASO standard MA. The cooling system holds exactly 0.70 L. Standard operating temperature ranges between 80 and 90 °C. Intake valve clearance is strictly listed at 0.08–0.12 mm in the cylinder head specification table. Torque for the cylinder head bolt sits at 22 Nm. Additionally, the radiator core width is documented at 229.0 mm. Safety is the highest priority in any professional workshop or home garage setting. Always ensure proper tooling and mechanical understanding before beginning maintenance, as mishandling high-pressure fluids or heavy engine components can lead to serious injury.
