Generators often operate in harsh conditions, making radiator problems more likely over time. Typical faults include:
Coolant leaks due to corrosion or vibration
Blocked or restricted cores reducing cooling efficiency
Damaged fins or tanks impairing heat transfer
Wear and ageing causing overheating and fluid loss
Internal contamination limiting overall performance
Our experienced engineers can quickly assess the issue and recommend either repair or full re-manufacture, depending on the condition of the radiator and your operational requirements.
