Radium Engineering Radiator Cap Type-A 1.5 Bar Black

Looking to keep your engine running cool and efficient? The Radium Engineering Radiator Cap Type-A 1.5 Bar is just what you need! Designed specifically for a variety of vehicles including Acura, Honda, Infiniti, Lexus, Mazda, Mitsubishi, Nissan, Saab, Subaru, and Toyota models from 1982 onwards, this radiator cap is a key player in enhancing your cooling system's performance.

Why Choose Radium Engineering?

Radium radiator caps are crafted with precision to improve cooling efficiency. They play a vital role in an upgraded cooling system, helping to safely maximize engine performance by regulating the coolant's boiling point. Each cap is made from durable stamped stainless steel and features high-quality silicone sealing elements that outperform traditional natural rubber gaskets.

Pressure Ratings

We offer three pressure ratings to suit your needs:

• 1.1 Bar (16.0 psi)
• 1.3 Bar (18.9 psi)
• 1.5 Bar (21.8 psi) - perfect for those who demand a little extra from their cooling system!

By increasing the radiator coolant pressure, you effectively raise the boiling temperature of the coolant. This means added safety and a reduction in the risk of air pocket cavitation at the water pump, ensuring your engine stays cool under pressure.
