Cusco Aluminum Radiator Cap Subaru BRZ / Toyota 86 / Scion FR-S

This is a Cusco aluminum radiator cap designed for the Subaru BRZ, Toyota 86, and Scion FR-S. A radiator cap is more than just a lid; it's a crucial component that maintains the proper pressure within your cooling system. By holding pressure, it raises the boiling point of your coolant, helping to prevent overheating, especially under demanding driving conditions.

Crafted from durable aluminum, this Cusco cap is built to withstand the heat and pressure cycles of your engine. It features a 1.3 kg/cm² pressure rating, which is a common upgrade from stock caps on these vehicles, allowing the cooling system to operate at a slightly higher pressure. This can contribute to improved thermal management, ensuring your engine stays within its optimal operating temperature range. The solid construction means it’s a well-built part that should last.

When replacing your radiator cap, it's a good idea to inspect your hoses and thermostat as well. This Cusco cap is a direct replacement for the factory unit, making installation straightforward.
