Product Description
Over time, the plastic coolant expansion tanks included by Honda/Acura can weaken and fail due to heat and pressure cycles. The PRL Coolant Expansion Tank kit replaces the factory tank with a more robust aluminum version. The PRL 6061 aluminum tank withstands temperature changes and holds higher pressures, so it outlasts the factory tank. The PRL reservoir also more than doubles the tank's coolant capacity to 1.32 quarts (1.25 liters), while the stock tank only holds 0.58 quarts (0.55 liters). 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.
The PRL tank is constructed from 3mm thick aluminum and features internal baffling to prevent coolant sloshing and cavitation. The kit includes all necessary fittings for either the FK8/FL5/DE5 Civic Type-R/Integra Type-S applications or the 2016-2021 Civic with the 1.5T engines.
