Steeda S550 Mustang Coolant Expansion Tank
The Steeda aluminium coolant expansion tank replaces the Mustang’s original plastic reservoir. It gives the engine bay a cleaner appearance and provides a durable alternative for repeated high-temperature use, including upgraded-radiator installations.
Bolts into the original position and uses the factory pressure cap. The billet filler neck includes an overflow connection. Integral aluminium hose fittings avoid separate screw-in adapters.
Choose black powder-coated 555-0600 or silver 555-0601.
