Additional Notes

  • The Chevrolet Blazer (USA / CAN) 4.3 V6 rear differential holds 1.85 liters across all rear differential configurations, whether standard or equipped with a differential lock, and regardless of use condition.
  • The AWD variant adds a front differential with a capacity of 1.2 liters, which is notably smaller than the 1.85-liter rear differential capacity shared across both the standard and AWD configurations.
  • Under normal use conditions, the rear differential fluid change interval is set at 160,000 km, with a check interval of 12,000 km applying to both standard and AWD rear differentials.
  • Under severe use conditions, the rear differential fluid change interval is halved to 80,000 km, while the 12,000 km check interval remains unchanged relative to normal use.
  • The AWD front differential follows the same interval structure as the rear: a 160,000 km change interval under normal use and 80,000 km under severe use, each with a 12,000 km check interval.
  • Rear differentials equipped with a differential lock carry a first-change-only interval of 12,000 km, applied at 1.85 liters capacity, which precedes the standard ongoing change intervals for both normal and severe use conditions.
  • The first-change-only specification for the differential lock configuration applies identically to both the standard 4.3 V6 and the AWD 4.3 V6, with the same 12,000 km change point and 1.85-liter capacity in each case.
