Additional Notes
- The Pontiac G3 1.6 (USA) cooling system holds 6.3 liters of coolant, a figure that reflects the total system fill volume including the radiator, engine block passages, and reservoir.
- The 150,000-mile coolant change interval on the G3 1.6 (USA) applies under normal use conditions, meaning standard driving without the elevated thermal stress or shortened drain cycles associated with severe service classifications.
- A 6.3-liter cooling system capacity is relatively modest, consistent with a small-displacement 1.6-liter four-cylinder engine where the overall coolant circuit volume is proportionally limited compared to larger powerplants.
