Coolant Expansion Tank - 96-04 Mustang

The MOROSO Coolant Expansion Tank for 1996–2004 Mustang is a direct-fit replacement designed to maintain optimal cooling system pressure and fluid capacity in first-generation New Edge and SN-95 generation muscle cars. Built for enthusiasts and mechanics who demand reliable thermal management during aggressive driving, track use, or engine modifications, this expansion tank replaces the factory unit with a more durable aftermarket solution.

MOROSO engineered this expansion tank to provide superior fluid dynamics and degassing compared to original equipment, reducing air pockets that can compromise heat transfer and cause hot spots in the engine block. The tank's design accommodates higher coolant temperatures and circulation rates typical of modified 3.8L and 5.0L engines, while the integrated cap and overflow system prevents pressurized coolant loss during thermal cycling.

Ideal for street-strip Mustang owners, weekend drag racers, and any technician rebuilding the cooling system, this tank ensures a precise fitment that sits flush against the radiator shroud without interference with serpentine belt routing or under-hood components, maintaining stock-like aesthetics while delivering measurable cooling system reliability gains.
