An old plastic coolant reservoir / overflow or expansion tank will eventually wear out and crack. These PRL coolant overflow and expansion tanks are made of aluminum, ensuring that it will not crack or wear out over time.

Each PRL reservoir / overflow and expansion tank is made from robust 3mm 6061 aluminum, laser cut and TIG-welded for a perfect overall fit and function. Each option is finished in a black or red anodized finish with a laser engraved PRL logo on the expansion tanks. The fittings are billet machined for a tight leak free fit as well! A sight glass on the side allows you to see how full the tank is and top it off as needed. Each kit is direct fit and reuses factory mounting points for an easy install on your Acura Integra.

Key Features:

• Made of robust 3mm 6061 aluminum for strength and durability. Will not crack or wear out like the factory tank.
• Expansion tank applications feature a built-in baffle that prevents sloshing and cavitation, which means coolant is kept near the overflow port during spirited driving, which prevents air from getting into the cooling system.
• Expansion tank applications hold more than double the coolant capacity compared to your factory tank! This results in a greater volume of coolant to carry heat away from your engine. In addition, the PRL expansion tanks can withstand higher pressures as well.
• Improves the look of your engine bay.
• Completely bolt-on design; includes or reuses all required hardware, hoses, and fittings.
• Anodizes in black or red with a laser etched PRL logo on expansion tank applications.
• Billet machined fittings and sight glass.
• Buna-N O-rings for unmatched temperature and leak resistance.
• All kits include a high pressure radiator cap and installation hardware (hose, clamps, bracket, etc.) as applicable.
