Additional Notes

  • The Pontiac Firebird (USA / CAN) 3.4-liter engine carries a cooling system capacity of 11.6 liters when paired with an automatic transmission and 11.8 liters when paired with a manual transmission, a modest but consistent difference that reflects the varying heat exchange demands of each drivetrain configuration.
  • The 3.4-liter cooling system capacity figures of 11.6 liters (automatic) and 11.8 liters (manual) remain identical across the 1992-1993 and 1994-1995 model year groupings, indicating no revision to the cooling system volume between those periods.
  • The 5.7-liter Trans Am configuration carries a notably larger cooling system capacity of 14.5 liters in manual transmission applications, a figure approximately 25 percent greater than the 3.4-liter counterpart, which is consistent with the higher thermal output of a larger displacement V8 engine.
  • When the 5.7-liter Trans Am is equipped with an automatic transmission, the cooling system capacity is listed at 14.3 liters, a reduction of 0.2 liters compared to the manual transmission variant of the same engine.
  • The 5.7-liter Trans Am specifications appear across two overlapping year range entries, covering 1993-1997 and 1994-1997, with both entries sharing identical capacity values and service intervals.
  • All four specification rows across both engine families share a uniform coolant change interval of 50,000 km or 24 months under normal use conditions, whichever comes first.
