Coolant Expansion Tank Corvette 05-13

The Coolant Expansion Tank Corvette 05-13 is a precision aluminum reservoir engineered for the C6-generation Chevrolet Corvette (2005–2013). This component manages coolant overflow and maintains optimal pressure within the engine cooling system, preventing air pockets and cavitation that can degrade cooling efficiency. Built to OEM specifications, this expansion tank is essential for anyone maintaining or upgrading their Corvette's thermal management system, whether for track performance or daily driving reliability.

Manufactured by MOROSO, a leader in cooling system components, this tank features a natural aluminum finish that resists corrosion while providing excellent heat dissipation properties. The aluminum construction reduces weight without compromising durability, making it ideal for performance-oriented builds. The compact footprint (11.3 x 9.6 x 15.2 inches) fits within the Corvette's engine bay constraints, and the 3.8-pound weight contributes to improved power-to-weight ratio—a critical consideration for sports car enthusiasts. The design incorporates proper filler neck geometry and vent passages to ensure efficient coolant circulation and system pressurization.

Corvette owners undertaking cooling system refreshes, engine modifications, or preventative maintenance will find this expansion tank a direct-fit replacement that restores system integrity. Installation requires no modifications to existing mounting points, making it accessible to both professional technicians and experienced DIY builders. This tank is sold individually and pairs seamlessly with OEM or upgraded radiators and water pump configurations, ensuring your C6 Corvette maintains peak operating temperatures under all driving conditions.
