Additional Notes
- The Yamaha YW Zuma (USA) cooling system holds a total capacity of 0.5 liter, which represents the full system fill volume including the radiator and internal passages.
- A separate reservoir capacity of 0.26 liter is specified for both the 2011-2014 and 2015-2019 model year ranges, accounting for roughly half the total system volume on its own.
- Both model year ranges share the same 36-month coolant change interval under normal use conditions, meaning the drain-and-refill service schedule remained consistent across the full 2011-2019 span.
- The 2015-2019 YW 50 Zuma introduced an additional inspection interval not present in the earlier specification, calling for a coolant check at every 2,000 miles or 6 months under normal use, whichever comes first.
- The 2011-2014 specification carries no mileage or short-interval check requirement, making the 36-month change the sole scheduled coolant service event listed for those model years.
