Jeep Wagoneer, WS (USA / CAN)

Additional Notes

• The Jeep Grand Wagoneer 3.0 AWD carries a main cooling system capacity of 15.7 liters, which reflects the total volume of coolant the engine circuit holds when filled to specification after a full drain and refill service.
• The Grand Wagoneer 3.0 AWD also lists a separate intercooler cooling circuit with a capacity of 3 liters. Turbocharged engines commonly use a dedicated low-temperature coolant loop to manage charge air temperatures independently from the main engine circuit.
• The Grand Wagoneer 6.4 V8 AWD has the largest main cooling system capacity in the lineup at 17.8 liters, reflecting the greater thermal mass and larger block volume associated with a naturally aspirated 6.4-liter V8 engine compared to the 3.0-liter turbocharged unit.
• The Wagoneer 5.7 V8, in both AWD and non-AWD configurations, shares an identical main cooling system capacity of 16 liters. The 5.7 V8 sits between the 3.0 inline-six and the 6.4 V8 in terms of coolant volume requirements.
• The Wagoneer 3.0, across AWD and non-AWD variants, carries the same 15.7-liter main cooling system capacity as the Grand Wagoneer 3.0 AWD, indicating the engine cooling circuit volume is consistent regardless of drivetrain configuration or trim level.
• The intercooler cooling circuit on the Wagoneer 3.0 AWD and the non-AWD Wagoneer 3.0 both specify 3 liters, matching the Grand Wagoneer 3.0 AWD intercooler capacity. The 3.0-liter engine shares the same secondary circuit specification across all Wagoneer variants in which it appears.
• All coolant entries across every configuration listed carry a uniform service interval of 150,000 miles or 120 months under normal use conditions. A 120-month interval equals 10 years, placing these specifications in the category of extended-life coolant systems, which typically use organic acid technology or hybrid organic acid technology formulations designed to resist degradation over long service periods.
