Additional Notes

  • The GMC Jimmy 4.3 V6 cooling system capacity differs depending on transmission type, holding 11.1 liters with an automatic transmission and 11.3 liters with a manual transmission across both the 1993-1998 and 1999-2002 model year ranges.
  • The 0.2-liter difference between automatic and manual transmission configurations reflects the varying thermal load and plumbing routed through each drivetrain setup, which affects the total coolant volume the system accommodates.
  • The normal-use coolant change interval for the 4.3 V6 is set at 60,000 km or 48 months, whichever comes first, applying uniformly to both the 1993-1998 and 1999-2002 generations.
  • A 48-month maximum service life on coolant, regardless of mileage, reflects the chemical degradation of corrosion inhibitors over time, which occurs independently of how much the vehicle has been driven.
  • The capacity and change interval specifications remain identical between the 1993-1998 and 1999-2002 model year groups, indicating no revision to cooling system service requirements across the full 1993-2002 span covered by the 4.3 V6 engine.
