Additional Notes
- Both the 6900-1 and 6900-2 configurations share an identical cooling system capacity of 7 liters across the full 1984-1999 model range.
- The 7-liter figure represents the total cooling system fill volume, which typically accounts for the radiator, engine block passages, heater core, and connecting hoses taken together.
- Both configurations carry a normal use condition designation, meaning the stated 7-liter capacity applies under standard operating circumstances rather than severe-duty or first-fill scenarios.
