Additional Notes
- The Yamaha SZR 660 cooling system holds 1.4 liters of coolant, a figure that represents the total system fill volume rather than a partial or overflow-only quantity.
- A 1.4-liter capacity is consistent with a single-cylinder liquid-cooled engine of moderate displacement, where the coolant circuit covers the cylinder head, cylinder barrel, and associated passages without the larger volumes seen in multi-cylinder configurations.
- The specified change interval is 24,000 km or 24 months, whichever comes first, and both conditions apply under normal use.
- The dual-trigger interval structure, combining a distance threshold with a time limit, reflects the fact that coolant degrades chemically over time regardless of mileage accumulated.
- The normal use designation attached to the 24,000 km / 24-month interval means the specification does not account for more demanding operating conditions, which in practice can accelerate coolant breakdown through elevated thermal cycling.
- A single set of capacity and interval figures covers the entire 1996-2001 production span of the SZR 660, indicating no revision to coolant system specifications occurred across those model years.
