Scion xD (USA / CAN)

Additional Notes

• The Scion xD 1.8 ZSP110 cooling system holds 4.9 liters when paired with an automatic transmission and 5 liters when paired with a manual transmission, a 0.1-liter difference that reflects the slightly different coolant routing and heat exchange demands associated with each transmission type.
• Across all model years and both market variants, the cooling system capacity figures remain constant at 4.9 liters (automatic) and 5 liters (manual), indicating no capacity change was introduced between the 2008 and 2014 model years.
• USA-market specifications call for a coolant level check every 15,000 miles or 18 months, while Canadian-market specifications set the check interval at 8,000 km, reflecting the different unit-based service schedules used in each market.
• For USA-market vehicles in the 2008-2009 model years, the normal coolant change interval is 50,000 miles or 60 months, which equals a five-year or roughly 80,000 km service cycle under standard operating conditions.
• The first-change-only interval for USA-market xD models across 2008-2014 is 100,000 miles or 120 months, exactly double the normal change interval of 50,000 miles or 60 months. A first-change-only designation typically applies to the factory-fill coolant, which is formulated to last longer before the first drain and refill.
• Canadian-market specifications set the normal coolant change interval at 80,000 km for the 2010-2014 model years, while the first-change-only interval is 160,000 km, again representing a 2:1 ratio between the extended factory-fill life and the subsequent regular service cycle.
• The USA and Canadian market specifications share identical capacity values but differ in their interval units and numerical values, with the Canadian 80,000 km normal change interval being roughly equivalent to the USA 50,000-mile interval when converted, as 50,000 miles is approximately 80,467 km.
