Technical Notes:

Over time, the factory plastic coolant expansion tanks that Honda/Acura include from the factory can weaken and fail from heat and pressure cycles. The PRL Coolant Expansion Tank kit replaces the factory tank with a more robust aluminum version. Our 6061 aluminum tank will not be effected 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) allowing for a greater volume of coolant to carry heat away from the engine internals while maintaining a tidy engine bay.

Our tank is constructed from 3mm thick aluminum and features internal baffling to prevent coolant sloshing and cavitation. The kit includes fittings to fit both the 2017-22 FK8 Civic Type R as well as the 2023-25 FL5 Type R and 2024+ Acura Integra Type S. The FK8 fittings can also be used to mount this Expansion Tank on your 2017-21 Honda Civic SI.
