PRL Motorsports Black Coolant Overflow Reservoir Expansion Tank - Honda Civic 1.5T (2016-2021)

This PRL Motorsports coolant overflow reservoir expansion tank is made of 3mm thick 6061 aluminum and increases coolant capacity to 1.32 quarts, improving durability and heat dissipation.

• Our 6061 aluminum tank will not be affected by temperature and can hold higher pressures so it will out-last the factory tank.
• Our reservoir also more than doubles the tank's coolant capacity to 1.32 quarts (1.25 liters), while the stock tank only holds .58 quarts (.55 liters).
