Coolant Expansion Tank - 87-93 Mustang

The Coolant Expansion Tank – 87-93 Mustang (Model 80-230) by CANTON is a factory-replacement recovery tank engineered to maintain optimal coolant levels in your classic Ford Mustang's cooling system. As engine coolant heats and cools through normal operation, it expands and contracts—this tank safely captures overflow and prevents air from entering the system, protecting your engine from overheating and corrosion. OEM-style recovery tanks like this are essential for any Mustang owner restoring, maintaining, or upgrading their cooling capacity.

Constructed from lightweight aluminum with a natural (unpainted) finish, this 2.5-quart expansion tank features an external sight gauge that allows you to monitor coolant level at a glance without opening the reservoir. The aluminum construction resists corrosion better than plastic alternatives, while the sight gauge eliminates guesswork during routine checks or after cooling system work. Measuring 8.7 x 6.4 x 22.5 inches and weighing just 2.85 lbs, it integrates seamlessly into the engine bay of 1987–1993 Ford Mustangs without adding significant weight or complexity.

This tank suits Mustang enthusiasts, restoration shops, and DIY mechanics who demand OEM-quality cooling components for their classic pony cars. Whether you're rebuilding a cooling system, replacing a cracked or degraded factory tank, or upgrading to a more reliable recovery setup, the CANTON expansion tank delivers durability and proven fit. Installation is straightforward for third-generation Mustang platforms—simply connect the overflow hose from the radiator and any auxiliary cooling lines per your vehicle's original configuration. Keep your cooling system pressurized and your engine running cool with this purpose-built Mustang coolant recovery solution.
