LOCOZI Coolant Reservoir Tank — Direct-Fit for Chevy Trax/Tracker & Buick Encore 2013–2021, Includes Cap & Hoses

LOCOZI engine coolant reservoir tank is a direct-fit replacement expansion/overflow bottle with cap and hoses designed for Chevy Tracker, Trax and Buick Encore models (2013–2021).

Maintaining the cooling system starts with a reliable recovery tank. This LOCOZI coolant reservoir assembly replaces worn or cracked plastic tanks that lead to low coolant, leaks, or overheating symptoms. It ships with a surge cap, an air-discharge hose and a molded heater hose so you get a ready-to-install set that matches the original fitment numbers for many Buick and Chevrolet small SUVs.

How will this tank fix coolant loss or visible leaks?

A brittle or cracked reservoir cannot hold expanding coolant, which causes drops in fluid level and visible puddles. Replacing the tank restores the sealed expansion path and proper coolant recovery during engine warm-up and cool-down cycles.

• Direct replacement for OE numbers including 603-955, 95269001, 95201979, and others.
• Includes new surge cap to ensure proper pressure sealing and venting.
• Supplied hoses reduce the risk of old-hose deterioration causing fresh leaks.

What vehicles and engines does this LOCOZI reservoir fit?

This tank is produced to match the mounting points and hose connections on select Buick Encore and Chevrolet Tracker/Trax models produced between 2013 and 2021. It fits the common 1.4L and 1.8L turbocharged and naturally aspirated four-cylinder engine variants used in those lineups.

• Fits Buick Encore and Chevrolet Trax/Tracker model years 2013–2021 as listed in product fitment.
• Compatible with L4 engines 1.4L (1364–1399 cc) and 1.8L where specified.
• Cross-references OEM part numbers: 95128276, 96968691, 95380033, 1350235 and more.

What materials and quality features does this assembly offer?

The tank is molded from durable polypropylene designed to tolerate underhood heat, vibration and chemical exposure typical of cooling systems. While not an original equipment manufacturer (OEM) branded item, it is engineered as a direct replacement with reinforced connection points and a pressure-cap that restores system venting.

• High-quality PP plastic resists heat and cracking better than aged stock tanks.
• Includes a premium molded heater hose and an air bleed/discharge hose for installation completeness.
• Lightweight yet durable construction that replicates OEM fitment and function.

How should I prepare for installation and maintenance?

Installations are best performed by a qualified technician, but basic prep helps: drain the cooling system to the proper level, remove old hoses and clamps, and replace hose clamps when installing new hoses. Always inspect related components like radiator neck, caps and coolant condition while replacing the reservoir.

• Recommended: replace hose clamps during installation to secure new hoses.
• Bleed air from the system following the vehicle maker’s procedure to prevent hot spots.
• Check coolant type and top up or replace according to the vehicle’s specifications.

Who is this for: The LOCOZI Engine Coolant Reservoir Tank kit is intended for owners, independent mechanics and service shops working on 2013–2021 Buick Encore, Chevrolet Trax and Tracker vehicles that require a reliable, cost-effective replacement for a cracked, leaking or failed coolant expansion tank. It’s ideal for anyone who wants a complete replacement set—tank, cap and hoses—that aligns with multiple OE part numbers and restores proper coolant recovery and venting without sourcing individual components.
