How well is your mine site prepared for summer?
As summer heats up across Australian mine sites, so does the pressure on your fleet’s heavy-duty cooling equipment. December through February is the summer shutdown season, where the combination of extreme ambient temperatures and back-to-back scheduled maintenance windows leaves no room for error.
For maintenance planners, the challenge is twofold: preventing heat-induced engine failure and navigating the inevitable parts shortages that plague the industry during peak demand. Whether you are managing a fleet of Caterpillar, Komatsu, or Hitachi machines, securing a reliable radiator exchange or a full cooling system overhaul is the difference between a productive 2026 and a summer of costly, unplanned downtime.
The summer shutdown challenge: why cooling systems fail
Australian summer heat places extreme stress on cooling components, often accelerating issues such as core fatigue and coolant degradation. Constant exposure to high temperatures push nosecones, radiators, charge air coolers, and oil coolers to their limits, increasing the chance of failure and triggering the need for cooling overhauls during shutdown.
At the same time, summer shutdown periods place added pressure on the mining supply chain. High demand and extended OEM lead times can make sourcing critical cooling components difficult and a high-risk strategy.
The result is often:
- Extended downtime during scheduled maintenance.
- Pressure on maintenance teams.
- Reduced mechanical availability and productivity.
- Loss in productivity.
Reduce downtime with Coxons specialist cooling solutions
Coxons helps mine sites stay on schedule during summer shutdowns and high-demand periods by addressing the most common causes of cooling-related downtime.
1. Radiator and Nosecone Service Exchange
When shutdown windows are tight and extended OEM lead times put schedules at risk, Coxons’ Service Exchange and Nosecone Service Exchange programs provide fully rebuilt, ready-to-install cooling modules for shutdown schedules.
These solutions are ideal for Caterpillar, Komatsu, Hitachi, Mesabi, and Liebherr fleets, enabling fast change-out that reduces labour time and helps keep planning on track.
2. Mining Component Repair and Return
When full exchange isn’t required, Coxons offers Mining Component Repair and Return services for radiators, charge air coolers and oil coolers.
Each component undergoes detailed inspection, repair and performance testing to
AS-certified and OEM standards, giving maintenance teams confidence in quality, reliability and long-term performance before assets return to site.
3. MineCool aftermarket cooling components
For sites looking for a reliable OEM alternative, Coxons supplies heavy-duty aftermarket cooling components through its exclusive Australian distribution of MineCool.
Designed specifically for harsh Australian mining conditions, MineCool components feature direct-fit design and local stock availability — helping reduce OEM lead times and minimise downtime during critical shutdown windows.
4. Supporting scheduled maintenance
Effective scheduled maintenance depends on having the right components available at the right time when shutdowns begin or when maintenance is scheduled – not a week later.
Coxons works closely with mine sites to align cooling solutions with planned maintenance schedules. With MineCool’s range of over 300 cooling components and Coxons’ ready-built nosecones and radiators, turnaround times are improved and HME assets stay productive through peak summer periods.
