Chevrolet Uplander (USA / CAN)

Coolant capacity & service interval

Chevrolet Uplander (USA / CAN) coolant capacity ranges from 10,7 to 12,2 liters. Service intervals include a 12 month check and a 150000 mile or 60 month change. The data covers 2 configurations.

Additional Notes

  • The Chevrolet Uplander 3.5 V6 cooling system holds 10.7 liters when equipped with front air conditioning, and 12.2 liters when a rear air conditioning unit is also present. The 1.5-liter difference between the two figures reflects the additional coolant volume required to service the rear climate circuit.
  • Both the 2005 and the 2006-2008 Uplander 3.5 V6 share identical coolant capacities of 10.7 liters and 12.2 liters respectively, meaning no capacity revision was introduced across the full 2005-2008 production span for the 3.5 V6 engine.
  • Under normal use conditions, the coolant change interval is specified at 150,000 miles or 60 months, whichever comes first. The 60-month figure equals five years, making calendar time the more likely limiting factor for vehicles driven at average annual mileages.
  • A separate coolant check interval of 12 months is specified alongside the longer change interval. A 12-month check cycle means the system condition is evaluated annually well before the full drain-and-fill service becomes due at 60 months.
  • The 150,000-mile change interval is associated with normal use conditions. At that mileage threshold, the coolant's corrosion inhibitors and pH stability are considered to have reached the end of their effective service life under non-severe operating patterns.
