Technical Specification Highlights

Need fast reference numbers? The manual provides precise factory tolerances. For example, it specifies cylinder head nut torque at 35–40 Nm (25.5–29.0 lb-ft) and an engine oil capacity of 4.8 liters for a filter change. It lists cold valve clearances (0.10–0.15 mm) and spark plug gaps (0.6–0.7 mm) for optimal ignition.
