What Is a Diesel Generator Radiator and How Does It Work?

A diesel generator radiator is a cooling system that reduces the heat generated by a diesel generator.

A generator produces energy by converting fuel into mechanical energy, and in the process, heat is also generated. This heat can damage the generator and surrounding components, making the radiator a vital part of the cooling system. The radiator absorbs the heat from the engine coolant and removes it, maintaining the normal temperature level.

How does a diesel generator radiator work?

The engine coolant circulates in the engine and picks up heat before moving to the radiator. The coolant flows through to the radiator in pipes that are exposed to air, where the heat is reduced. Finally, the cooled-down coolant returns to the engine to pick up more heat, starting the process again.

Why is radiator efficiency important?

A poorly functioning radiator will impact the generator’s performance and could lead to overheating and shutdowns, which could disrupt your business operations. Ensuring that the radiator is in good working condition can save your business money and time spent on repairs or replacement.

Radiator maintenance

Poor maintenance of diesel generator radiators can lead to several problems including corrosion, blockages, and damaged gaskets. Neglecting or overlooking the maintenance of the radiator can result in costly repairs and downtime.

Here are our top tips for keeping the health of your generator in check in between maintenance visits:

  • Undertake a visual inspection – Problems with your generator can be uncovered with a thorough visual inspection – check parts like hoses and belts for any leaks and signs of wear. Also check your fuel, oil, and coolant levels.
  • Use high quality fluids – Your generator will run best with high quality coolant, oil, and fuel. Avoid contaminants and build-up that interfere with a generator’s performance by choosing high-quality fluids and testing the fuel regularly to ensure it is not degrading.
  • Run your generator regularly – Low usage of your generator can cause wet stacking’ or build up in the engine exhaust and air in your fuel system, leading to damage to the internal parts of your generator. It’s important to run your generator regularly for a short period of time to avoid any issues.
  • Only use Original Equipment Management (OEM) parts – OEM parts, including air filters, fuel filters and oil filters that are endorsed by the generator manufacturer can extend the life expectancy of your diesel generator and provide a predictable expense for your business.
