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 Melbourne?

    We service the entire Melbourne area and surrounding areas, including St Kilda, Fitzroy and Brighton. Contact us to confirm if we serve your specific location.

  • What is a liquid-to-air intercooler, and how does it work?

    A liquid-to-air intercooler cools compressed air before it enters the engine, improving combustion efficiency and performance. It uses coolant to absorb heat from the air passing through it. This type of intercooler is commonly used in turbocharged or supercharged engines to reduce intake temperatures and enhance power output.

  • Why does my engine overheat when idling but cool down while driving?

    This issue often results from a failing radiator fan, restricted airflow or a weak water pump. While driving, natural air circulation helps cool the radiator, but at idle, the fan must provide airflow. If the fan is not working properly, the engine temperature may rise, leading to potential overheating.

  • Why does my coolant level keep dropping without visible leaks?

    If your coolant level is consistently dropping but there are no visible leaks, it could indicate an internal issue, such as a blown head gasket, a cracked engine block or a leaking intake manifold gasket. These problems allow coolant to burn in the combustion chamber or mix with engine oil, requiring immediate diagnosis and repair.
