Additional Notes
- All three engine configurations listed for the Pontiac G5 (USA / CAN) share an identical coolant capacity of 7 liters, indicating a consistent cooling system volume across the 2.2 16V (110 kW), 2.2 16V (116 kW), and 2.4 16V variants.
- The 7-liter figure represents a service fill capacity, meaning the volume of coolant required when servicing the cooling system under normal operating conditions rather than a full mechanical overhaul of the engine block.
- A change interval of 150,000 miles or 60 months applies to all three configurations under normal use conditions, placing the G5 in a category of vehicles with extended-life coolant service schedules.
- The 60-month interval translates to a five-year replacement cycle, which aligns with the extended-life characteristics typical of modern ethylene glycol-based coolants formulated for long-service applications.
- The 2.2 16V (116 kW) variant carries a model year range of 2009-2009, meaning specifications for that engine apply exclusively to that single year within the broader 2005-2009 span covered by the G5 lineup.
- The 2.2 16V (110 kW) and 2.4 16V engines share the full 2005-2009 model year range, while the higher-output 2.2 16V (116 kW) represents a later, narrower production window within the same generation.
