Additional Notes

  • The Pontiac Trans Sport 2.3 16V carries a base cooling system capacity of 11.05 liters, which represents the standard service fill volume for vehicles without rear climate control.
  • When the 2.3 16V is equipped with rear air conditioning, the cooling system capacity rises to 12.75 liters, reflecting the additional coolant volume required to serve the extended circuit feeding the rear unit.
  • The 3.8 V6, covering model years 1991-1995, shares the same base cooling system capacity of 11.05 liters as the 2.3 16V, despite the difference in engine displacement and configuration.
  • Both engine configurations specify a coolant change interval of 60,000 km or 48 months under normal use conditions, meaning whichever threshold is reached first would govern the service timing in everyday driving.
  • The 2.3 16V engine is listed for model years 1992-1996, while the 3.8 V6 covers 1991-1995, indicating a one-year offset at both ends of the production span covered by these specifications.
