Frequently Asked Questions

Learn More
  • What areas do you service in Nowra?

    We service the entire Nowra area and surrounding areas, including West Nowra, South Nowra and Brundee. Contact us to confirm if we serve your specific location.

  • How often should I flush my cooling system?

    It is recommended to flush your cooling system every 2 to 5 years, depending on your vehicle manufacturer’s guidelines. Regular flushing helps remove rust, debris and old coolant that can clog the radiator and reduce cooling efficiency. If you frequently drive in extreme conditions or use a performance radiator, flushing may be required more often to maintain peak performance.

  • What type of coolant should I use in a performance radiator?

    The type of coolant you should use depends on your vehicle manufacturer’s specifications. High-performance radiators may require specialised coolants with enhanced heat transfer capabilities and corrosion inhibitors. Using the correct coolant ensures optimal cooling efficiency and prevents issues such as rust buildup and water pump failure.

  • How do I know if my radiator is failing?

    There are several signs that indicate a failing radiator, including frequent engine overheating, visible coolant leaks, sludge buildup inside the radiator, rust or corrosion on the radiator fins and low coolant levels that require constant refilling. If you notice any of these issues, it’s important to have your radiator inspected and repaired to prevent engine damage.
