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 Port Macquarie?

    We service the entire Port Macquarie area and surrounding areas, including North Shore, Thrumster and Wauchope. Contact us to confirm if we serve your specific location.

  • Can a radiator be repaired, or does it need to be replaced?

    Minor radiator issues, such as small leaks or damaged fins, can sometimes be repaired using sealants or welding. However, significant damage, such as large cracks, severe corrosion or clogged coolant passages, often requires a full replacement. A professional assessment can determine whether repair or replacement is the best option.

  • How does a thermostat failure impact engine cooling?

    A stuck-closed thermostat blocks coolant flow, causing overheating, while a stuck-open thermostat prevents the engine from reaching its optimal temperature, reducing efficiency. Either issue can affect performance and fuel economy. Replacing a faulty thermostat ensures proper temperature regulation and prevents potential engine damage caused by excessive heat or inefficient warming.

  • What is the ideal operating temperature for a vehicle's cooling system?

    Most vehicles operate efficiently between 85°C and 105°C. Performance vehicles may require lower temperatures for optimal power output. A well-functioning radiator, thermostat and coolant system help maintain this range, preventing overheating or excessive cooling, both of which can impact engine performance, fuel economy and overall reliability.
