Engine Coolant Reservoir in Black Aluminum for Jeep Wrangler JL/JLU and Gladiator JT
Upgrade the Jeep Wrangler JL/JLU and Gladiator JT cooling system with the Jeep Wrangler JL/JLU Gladiator JT Engine Coolant Reservoir in Black Aluminum. This aftermarket reservoir is engineered to bolt into the OEM installation position on 2018–2024 Wrangler JL/JLU and 2020–2024 Gladiator JT 2.0T & 3.6L models, matching the original hole layout for a seamless fit with no cutting. Crafted from durable aluminum, it stays lightweight while delivering strong pressure resistance. The design features a reserved pressure relief hole to prevent over-pressurization; when coolant pressure in the radiator rises, excess coolant flows through a dedicated channel to the reservoir, protecting hoses and the radiator from damage. It functions like the factory kettle, helping your engine maintain optimal temperatures during demanding driving conditions and off-road adventures. With a clean OEM-grade finish, it preserves your vehicle’s under-hood aesthetics while offering reliable performance.
Benefits & Tips
- Overflow protection in extreme heat or heavy-duty use: the reserved relief channel safely redirects excess coolant to the reservoir, reducing the risk of hose or radiator failure.
- Easy, tool-free installation: designed for OEM hole installation without cutting, ensuring a snug, factory-like fit and seal.
- Precise compatibility: matches OE numbers 68364312AC/68364312AA or 68364312AB/68388115AB, making it a straightforward replacement for 2018–2024 Wrangler JL/JLU and 2020–2024 Gladiator JT models with 2.0T or 3.6L engines.
