LOCOZI Coolant Reservoir Tank for Chevy Tracker/Trax & Buick Encore (2013–2021) — Cap & Hoses, OE-Fit Replacement

LOCOZI's Engine Coolant Reservoir Tank is a direct-fit replacement expansion tank with cap and hoses designed to restore proper coolant recovery and reduce leaks for select Chevy Tracker, Trax and Buick Encore models.

If your vehicle shows signs of coolant loss, visible cracks, low coolant warnings, coolant smell, or intermittent overheating, the reservoir tank can be the source. This LOCOZI assembly includes the molded reservoir, surge cap, air discharge hose and a premium molded heater hose so you receive the core parts needed for a like-for-like swap. Made from heat-resistant PP plastic, the tank resists vibration and thermal wear and is intended to replicate OE fit and function for model years 2013–2021 where the listed part numbers apply.

How will replacing this reservoir tank help my car's cooling system?

Swapping a cracked or leaky reservoir restores the system's ability to capture and return expanding coolant, preventing air pockets and maintaining proper fill levels. A functioning tank and cap help maintain system pressure and reduce the chance of overheating caused by coolant loss.

• Restores coolant expansion and recovery function to radiator and engine block.
• Prevents external leaks and coolant odor that signal failing plastic or seals.
• Helps maintain correct system pressure with a matching surge cap.
• Reduces air intrusion that can cause hotspots and inconsistent temperature readings.

• Included: 1 x coolant reservoir tank, 1 x surge/cap, 1 x coolant air discharge hose, 1 x molded heater hose.
• Recommended: new hose clamps, coolant refill, and professional or experienced DIY guidance.
• Material: heat-resistant polypropylene (PP) for durability and vibration resistance.
• Note: Not an OEM part but designed as a direct replacement with matching form and function.

How can I tell when the reservoir needs replacement?

Visible cracks, coolant pooling beneath the vehicle, persistent low-coolant dashboard messages, or a sweet coolant odor are common indicators the plastic tank or its hoses are failing. If you see coolant level fluctuation without obvious external leaks, internal cracking or a failing cap can allow air in and coolant out.

• Look for hairline cracks, deformed plastic, or coolant residue on and around the tank.
• Monitor coolant level: rapid drops between fills indicate leaks or evaporation through a damaged tank.
• Heat cycling and age can make older tanks brittle—inspect routinely on high-mileage vehicles.
• Replace hose clamps when installing new hoses to ensure a secure, leak-free connection.

Who is this for: This LOCOZI reservoir assembly is intended for owners, mechanics, and fleet operators who need a cost-effective, direct-fit replacement for coolant recovery tanks on compatible Buick Encore, Chevrolet Trax and Tracker vehicles from 2013–2021. It suits drivers who prefer a full replacement kit including cap and hoses to reduce parts sourcing, plus technicians who will install with the correct tools and new clamps for a reliable repair.
