Generator Water Leaks

Potential causes of water leaks

A regular generator service can highlight potential problems, preventing water leaks from occuring.

However, if you suspect that you have a generator water leak or may have a non-identified water leak, follow the procedure below:

  • Ensure the generator is turned OFF whilst you locate the water leak.
  • Do a visual check of the entire generator, especially around the area of the leak. Check the radiator, looking for cracked hoses, non-tightened jubilee clips etc.
  • Check for corrosion, weak welding joints at the top of the radiator, and the bottom connections where the rubber hoses attach. The radiator cap should be secure and tight.
  • Now use your spill kit to soak up the water leak.
  • Check the integrity of all fuel hoses and tighten hose clamps if necessary. Touch the hoses and check for weaknesses and perished rubber (finger press).
  • Inspect the fuel tank to ensure that NO water has entered the diesel fuel.

If you can’t find the water leak

  • Top-up the radiator to maximum and start the generator again if the source of the leak still isn’t apparent.
  • A previous spill or rainwater leaking in through a hole in the canopy roof may turn out to be the cause of your suspected ‘leak’.
  • Should the generator water leak reappear, then go through the above advice once more. This time it may be that the thermostat has failed, causing the generator water temperature to become HOT and force its way out of the coolant system. Replace the thermostat with a new, genuine manufacturers part.
  • Then re-start the generator.
  • If you still cannot find the water leak, STOP the generator to avoid damage to the engine and arrange for a local generator engineer to visit site.
  • The majority of the above can be avoided by PowerContinuity preventative service and maintenance.
