  • What areas do you service in Wollongong?

  • What is a heavy-duty radiator, and how is it different from a standard radiator?

    A heavy-duty radiator is designed for industrial, agricultural and commercial vehicles that operate under extreme conditions. These radiators have reinforced cores, larger cooling capacities and durable materials like high-grade aluminium or copper-brass to withstand high heat loads, vibrations and harsh environments compared to standard vehicle radiators.

  • Why do industrial machines require specialised radiators?

    Industrial machines generate significant heat due to prolonged operation and high engine loads. Specialised radiators ensure efficient cooling to prevent overheating, maintain consistent performance and extend engine life. These radiators are built with heavy-duty materials to endure tough conditions, making them essential for construction, mining and agricultural equipment.

  • How often should a heavy-duty radiator be serviced?

    Regular maintenance is crucial for heavy-duty radiators, typically every 6 to 12 months, depending on usage. Inspections should include checking coolant levels, flushing the system, cleaning radiator fins and inspecting for leaks or blockages. Preventative maintenance helps avoid costly repairs and ensures optimal cooling efficiency.
