What is the pressure rating for this Koyo radiator cap?

This Koyo Hyper Radiator Cap is designed to hold 1.3 kg/cm² of pressure. This rating is important for maintaining the correct pressure within your vehicle's cooling system.

Why does the plunger style matter for my Subaru BRZ?

The shallow plunger style is specifically designed to work correctly with the radiator neck on certain vehicles, including the Subaru BRZ, Scion FR-S, and Toyota 86. Using the correct plunger style ensures the cap seals properly and maintains the intended system pressure.

How do I know if I need to replace my radiator cap?

A radiator cap should be replaced if it's visibly damaged, the seal is cracked or brittle, or if you're experiencing consistent coolant loss or overheating issues that can't be attributed to other cooling system components. It's a simple maintenance item that plays a vital role in your cooling system's health.

About this part

Product Details

When you're pushing your 2013-2017 Subaru BRZ hard, especially on the track or during spirited drives, keeping your cooling system working at its best is key. This Koyo Hyper Radiator Cap is designed to help your system maintain the correct pressure, which is crucial for efficient heat transfer and preventing boil-over.

This cap features a shallow plunger design, which is important for certain Subaru and Toyota applications like the BRZ, FR-S, and 86. It's built to hold pressure at 1.3 kg/cm², a common spec for these vehicles, ensuring your coolant stays within its optimal operating range. A well-pressurized cooling system raises the boiling point of the coolant, giving you a little extra margin when things heat up.

It's a straightforward replacement for your stock cap. Just make sure your old cap is cool before removing it, and then simply swap this one in. It's a simple way to ensure a critical part of your cooling system is functioning as it should.
