Additional Notes
- The Ford Windstar (USA) 3.0 V6 from 1994-1998 carries a base cooling system capacity of 13 liters, rising to 13.2 liters when the vehicle is equipped with a 4-zone air conditioning system.
- The modest 0.2-liter increase on the 1994-1998 3.0 V6 with 4-zone air conditioning reflects the small additional coolant volume required to serve the rear climate control circuit.
- From 1998-2001, both the 3.0 V6 and 3.8 V6 share identical cooling system capacities: 14 liters in base form and 15 liters with the 4-zone air conditioning system, representing a full 1-liter addition over the base figure.
- The 1-liter difference between base and 4-zone air conditioning configurations on the 1998-2001 models is notably larger than the 0.2-liter gap seen on the earlier 1994-1998 3.0 V6, indicating a more substantial rear cooling circuit in the later design.
- All configurations from 1994-2001 share a uniform service interval of 60,000 km or 48 months under normal use conditions, meaning coolant replacement is due at whichever threshold is reached first.
- The 3.8 V6 from 2001-2004 retains the same 14-liter base and 15-liter 4-zone air conditioning capacities as the 1998-2001 generation, so no capacity change accompanied the model year transition.
- A significant interval change applies to the 3.8 V6 from 2001-2004: the service interval extends to 150,000 km or 60 months under normal use conditions, compared to the 60,000 km or 48-month interval of all earlier configurations.
- The 150,000 km interval on the 2001-2004 3.8 V6 is consistent with the adoption of extended-life coolant formulations, which are chemically engineered to maintain corrosion inhibitor effectiveness over longer service periods than conventional coolants.
