Chevrolet Blazer, C1XX (USA / CAN)

Additional Notes

• All AWD configurations of the Chevrolet Blazer C1XX listed here share a rear twin-clutch differential fluid capacity of 0.75 liter, which represents a service fill volume typical of a compact rear drive module rather than a conventional open differential housing.
• The 2.0 AWD and 2.5 AWD variants carry a normal-use fluid change interval of 150,000 miles for the rear twin-clutch differential, placing routine maintenance well into long-term ownership cycles under standard driving conditions.
• Under severe use conditions, the 2.0 AWD (2019-2022) and 2.5 AWD (2018-2022) rear twin-clutch differential fluid change interval drops to 75,000 miles, exactly half the normal-use interval, reflecting the accelerated fluid degradation associated with demanding operating conditions such as frequent towing, off-road use, or extreme temperatures.
• The 3.6 V6 AWD variants, covering both the 2018-2022 and 2022- configurations, carry a normal-use rear twin-clutch differential fluid change interval of 75,000 miles, which matches the severe-use interval specified for the 2.0 and 2.5 AWD engines under the same service category.
• No severe-use interval row is listed for the 3.6 V6 AWD in the available specifications, whereas both the 2.0 AWD and 2.5 AWD include explicit severe-use entries alongside their normal-use counterparts.
• The 2.5 AWD rear twin-clutch differential specifications begin with the 2018 model year, while the 2.0 AWD entries start from 2019, indicating a one-year offset in the introduction of each engine variant within the Blazer C1XX lineup.
• The 0.75-liter capacity figure applies uniformly across all engine displacements and model year ranges in the specifications, suggesting the same rear drive module unit is shared across the 2.0, 2.5, and 3.6 V6 AWD configurations.
