Engine Coolant Reservoir Aluminum for Jeep Wrangler

Upgrade and safeguard your Jeep Wrangler's cooling system with this Engine Coolant Reservoir crafted from lightweight aluminum alloy. Designed as a direct replacement for Jeep Wrangler JL/JLU (2018-2025) and Gladiator JT (2.0L and 3.6L, 2020-2025), it replaces the plastic bottle with a robust aluminum tank that resists corrosion and high pressure, delivering lasting durability.

The reservoir is fully welded and features an O-ring seal to ensure a leak-proof connection and a reserved pressure relief hole to prevent excessive pressure. When coolant pressure rises, it can quickly release excess pressure to the outside, protecting radiators and hoses from rupture and maintaining cooling system stability during demanding driving or towing conditions.

Enhanced cooling efficiency comes from maintaining consistent coolant flow, helping prevent overheating and supporting reliable engine performance. This unit is engineered to withstand high temperatures and pressure, ensuring smooth operation and reducing the risk of coolant leaks compared to plastic bottles.

Easy to install as a direct replacement with no modification or drilling required. Note: this reservoir does not include a cap — please reuse the cap from your original Coolant Reservoir Recovery Bottle. Professional installation is highly recommended. Origin: Mainland China. Color: Black. Part numbers: 68364312AC, 68364312AA, 68364312AB, 68388115AB. OEM No. 68364312AC.
