The Radium Engineering Radiator Cap is a high-quality replacement component designed to improve your vehicle's cooling system performance. Engineered for enthusiasts and reliability-focused users, this radiator cap helps maintain optimal coolant pressure and temperature. By increasing the radiator pressure, it raises the coolant boiling point, providing a greater safety margin against overheating and cavitation. Constructed with durable materials, this cap ensures consistent sealing and pressure regulation, contributing to enhanced cooling efficiency and engine protection. Its robust design makes it suitable for demanding driving conditions, offering improved safety and peace of mind during high-performance or extended driving sessions.

This universal fitment radiator cap is compatible with a wide range of vehicles, making it a versatile upgrade for various makes and models. It is intended for use in applications where maintaining proper coolant pressure is critical, such as street driving, track days, or performance tuning. Installation is straightforward, typically involving a direct replacement of the existing cap. The kit includes the radiator cap itself, designed to meet or exceed OEM standards for pressure and durability. Suitable for vehicles requiring increased coolant pressure, this component enhances cooling system reliability and helps prevent overheating during demanding driving scenarios.
