Why Radiators Matter

Performance radiators are designed to manage the intense heat generated by high-performance, modified and heavy-duty engines. They work by efficiently dissipating heat through advanced cooling technology, ensuring your engine maintains optimal temperature even under extreme conditions.


A fully functioning and working cooling system is one of the most crucial parts of any performance engine. With the cost involved in today's market to build a high horsepower engine, your cooling system is insurance that you get the most possible use and longest life possible out of your engine.

Frequently Asked Questions

Learn More

  • What areas do you service in the Southern Highlands?

    We service the entire Southern Highlands area and surrounding areas, including Bowral, Moss Vale and Mittagong. Contact us to confirm if we serve your specific location.

  • Can a performance radiator prevent overheating?

    Yes, a performance radiator is specifically designed to improve cooling capacity, reducing the risk of overheating. It does this by allowing more coolant to circulate through a larger surface area, improving heat dissipation. This is especially beneficial for vehicles that generate excessive heat, such as race cars, modified vehicles and heavy-duty trucks.

  • Do I need an electric fan with a performance radiator?

    An electric fan can improve airflow through the radiator, enhancing its cooling performance. While some high-performance radiators rely on the vehicle’s mechanical fan, an electric fan provides additional cooling support, especially at lower speeds or in traffic where airflow is limited. Electric fans are particularly useful in high-performance, off-road or turbocharged vehicles.

  • What’s the difference between a single-pass and a dual-pass radiator?

    A single-pass radiator allows coolant to flow through the core once before returning to the engine, while a dual-pass radiator forces coolant to travel through the core twice. This extended path increases cooling efficiency by allowing more heat to dissipate before the coolant recirculates. Dual-pass radiators are often used in high-performance or racing vehicles where superior cooling is required.
