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 Brisbane?

    We service the entire Brisbane area and surrounding areas, including West End, Carindale and Upper Mount Gravatt. Contact us to confirm if we serve your specific location.

  • What is a coolant temperature sensor, and why is it important?

    The coolant temperature sensor monitors engine temperature and sends data to the ECU (engine control unit). It regulates fuel injection, ignition timing and cooling fan activation. A faulty sensor can cause inaccurate temperature readings, poor fuel economy or overheating issues, making timely replacement essential for optimal engine performance.

  • What happens if my radiator cap isn’t sealing properly?

    A faulty radiator cap can cause coolant loss, overheating and air entering the system, leading to reduced efficiency. Since the cap maintains system pressure, a weak seal allows coolant to escape or boil over. Replacing a damaged cap is a simple, cost-effective fix that prevents more serious cooling system issues.

  • Can a radiator blockage affect heater performance?

    Yes, a blocked radiator can prevent hot coolant from reaching the heater core, reducing or eliminating warm air output inside the vehicle. Clogs caused by rust, sediment or old coolant can restrict flow. Flushing the cooling system and replacing the coolant helps restore proper circulation and heater performance.
