TypeSpecifications

Additional Notes

  • The Pontiac Aztek 3.4 V6 carries a rear differential fluid capacity of 1.9 liters, a figure consistent with a service fill rather than a full overhaul volume, meaning the housing retains some residual fluid during a standard drain and refill procedure.
  • The rear differential service interval for the 3.4 V6 is set at a 12-month check cycle, applying specifically under normal use conditions rather than a mileage-triggered schedule.
  • A time-based interval of 12 months, as opposed to a distance-based one, reflects that differential fluid degradation in normal use is measured in elapsed time, accounting for moisture absorption and oxidation regardless of how many miles have accumulated.
  • The 1.9-liter rear differential capacity applies across the full 2001-2005 model year span of the 3.4 V6, with no variation in that figure recorded across those years.
