      Description

      Reliable Engine Cooling Support. Molded from high-temperature polyethylene, this Coolant Reservoir resists cracking and deformation under thermal cycling, ensuring consistent coolant delivery and preventing air locks in the system for years of service.

      Precision Fill Control. OEM-style translucent walls and molded level markings let you monitor coolant volume at a glance, while the integrated overflow tube routes excess fluid safely back to the radiator.

      Installation. Bolt-in replacement using factory mounting bosses and hoses—no trimming or modifications needed.

      Warranty. Covered for one year against manufacturing defects.

      Application. This Coolant Reservoir fits 1999–2004 Jeep Grand Cherokee WJ models.
