For owners of the 2017-2025 Honda Civic Type R and 2024+ Acura Integra Type S, PRL Motorsports offers a robust upgrade to your vehicle's cooling system. The PRL Coolant Expansion Tank replaces the factory plastic tank with a durable 6061 aluminum version, capable of withstanding higher temperatures and pressures.
This expansion tank more than doubles the coolant capacity to 1.32 quarts, compared to the factory tank's .58 quarts, allowing for better heat dissipation and a cleaner engine bay. Constructed from 3mm thick aluminum, the tank features internal baffling to prevent coolant sloshing and cavitation. The kit includes fittings for the 2017-22 FK8 Civic Type R, 2023-25 FL5 Type R, and 2024+ Acura Integra Type S, ensuring a perfect fit across these models.
The PRL Coolant Expansion Tank also boasts a laser-cut and TIG-welded construction, available in striking red or black anodized finishes, complete with laser-engraved logos. The kit includes all necessary fittings and a sight glass for easy monitoring. This high-quality tank not only enhances the performance and longevity of your cooling system but also adds a touch of style to your engine bay.

Hello, I purchased a PRL expansion coolant tank, but I’ve encountered an issue. I filled the coolant into the tank until it overflowed, yet I can’t see any coolant at all in the sight glass. Why is that?
How to tell if coolant level is at max? Should it be in middle where red dot is?
Would I be able to fit this or make this fit on a 2018 si coupe
