Product Overview

The Jeep Grand Cherokee 4.7 WJ Used Water Bottle, also known as a coolant reservoir, plays a vital role in maintaining your engine’s cooling system. It provides a storage chamber for excess coolant when the powerful 4.7L V8 engine reaches operating temperature, and it returns coolant to the radiator when the engine cools down. This process ensures proper coolant circulation, prevents overheating, and keeps your Jeep running reliably.

Over time, coolant reservoirs can weaken due to constant exposure to pressure and heat cycles. Cracks, leaks, or discoloration are common signs of failure. A faulty water bottle can cause coolant loss, reduced cooling efficiency, and potentially severe engine damage if ignored.

This OEM used water bottle has been sourced directly from a Jeep Grand Cherokee 4.7 WJ. Each unit is inspected for integrity, tested for leaks, and confirmed to be fully functional before resale. Choosing a genuine OEM used reservoir ensures compatibility, reliability, and cost savings compared to new replacements.
