Maximize Cooling & Reliability with PRL’s Aluminum Coolant Expansion Tank
Factory plastic coolant tanks on Honda and Acura models are prone to failure from repeated heat and pressure cycles. The PRL Motorsports Coolant Expansion Tank is a premium upgrade designed to eliminate those issues while boosting performance and style.
Precision-engineered from 3mm thick 6061 aluminum, this reservoir resists heat fatigue and handles higher pressure levels than stock plastic tanks. With over double the coolant capacity (1.32 quarts vs. 0.58 quarts), it allows better thermal management—carrying more heat away from your engine internals during spirited driving or track sessions.
Designed to fit seamlessly in the engine bay, this tank features internal baffling to reduce slosh and cavitation, ensuring stable coolant flow. Finished in anodized red or black with a laser-etched PRL logo, it blends function with aggressive aesthetics.

Red or black anodized finish with laser engraving
Internal baffling for fluid stability
Billet-machined barb fittings with Buna-N O-rings for leak-free sealing
