Additional Notes

  • The INFINITI G20 P10 cooling system capacity is listed as a range of 6.1 to 6.5 liters for the 1991-1996 model years, which reflects a service fill tolerance rather than a single fixed volume, and no separate reservoir figure is specified for that generation.
  • The P10 generation carries a change interval of 96,000 km or 48 months under normal use conditions, while the P11 generation shifts to a distance-based interval expressed in miles, set at 30,000 miles or 24 months for normal use across the 1999-2002 model years.
  • P11 models from 1999-2001 carry a fixed main cooling system capacity of 6.2 liters alongside a separate 0.8-liter reservoir capacity, giving a clear distinction between the primary circuit volume and the overflow or expansion tank volume.
  • For the 2002 model year, the P11 cooling system capacity varies by transmission type: 6.0 liters is specified with an automatic transmission or transaxle, while 6.1 liters applies with a manual transmission or transaxle, indicating that the transmission configuration affects the total coolant volume in the system.
  • The 0.8-liter reservoir capacity remains consistent across all P11 model years from 1999-2002, regardless of transmission type or model year within that span.
  • P11 models from 1999-2002 carry two distinct service intervals tied to use condition: the normal interval is 30,000 miles or 24 months, while the initial service interval is 60,000 miles or 48 months, meaning the first coolant change is scheduled at twice the distance and twice the time of subsequent changes.
  • The initial service interval of 60,000 miles or 48 months on P11 models applies to the same 6.2-liter main capacity and 0.8-liter reservoir as the normal interval for 1999-2001, with the 2002 year retaining the same dual-interval structure alongside the transmission-dependent capacity split.
