Additional Notes
- The Pontiac Firebird (EU) 3.4 carries a cooling system capacity of 11.6 liters when paired with an automatic transmission/transaxle, rising slightly to 11.8 liters with a manual transmission/transaxle.
- The 0.2-liter difference between automatic and manual transmission variants on the 3.4 reflects the small but measurable volume contribution of the transmission/transaxle to the overall cooling circuit.
- Capacity figures for the 3.4 remain identical across the 1992-1993 and 1994-1995 model year groupings, with both automatic and manual values unchanged between those two periods.
- The 5.7 and Trans Am configurations carry a notably larger cooling system, rated at 14.5 liters in standard form, which is approximately 2.9 liters more than the manual-transmission 3.4 variant.
- On the 5.7 and Trans Am, the automatic transmission variant reduces capacity slightly to 14.3 liters, a reversal of the pattern seen on the 3.4, where the automatic configuration holds the lower of the two capacity values as well.
- Capacity figures for the 5.7 and Trans Am are consistent across the 1992-1993 and 1994-1997 groupings, with no change in either the standard or automatic-transmission values between those periods.
- All four configurations share a uniform service interval of 50,000 km or 24 months under normal use conditions, whichever comes first.
