The thermostat has failed the thermostat opens as the engine gets warm to allow the air to flow around the radiator.Note: In this instance the coolant in the radiator may still be cool, as it is unable to be pumped from the engine to the radiator. In this case you would require a new water pump. The 'water pump' may have failed, leading to the coolant not flowing around the system.In this case you will need the radiator power flushing - but you might need a new radiator. This can happen due to using the incorrect coolant / water mixture, or incorrect type of coolant, or failing to change your coolant at the specified intervals. The inside of the radiator has corroded and the pipes that carry the coolant have clogged.

In this case get a professional to clear your radiator. The radiator matrix has gathered dust / oil and the air cannot pass in sufficient quantity, leading to the same effect as per 1.In this case reduce the load on the generator. (or the controller shutting it down by reading the sender). The load on the engine is too high, meaning the coolant cannot be cooled fast enough this leads to the coolant getting hotter and hotter until the coolant switch closes on fault causing shutdown.If the coolant is too hot the coolant switch may have shown a fault (normally by closing to earth) or coolant sender has indicated a reading (either resistance or voltage) that is too high - in both these instances the controller will take action to shut down the set. !Remember if you take off the radiator cap it may be pressurized and very hot! Take appropriate precautions! The coolant may also be very hot if it has overheated and steam may escape when opening the cap.

So why might the generator be shutting down?Ĭoolant heats up as the engine is running the coolant is pumped (by the 'water pump') through the radiator where the engine fan blows ambient air through the radiators matrix to reduce the coolants temperature. It is normal not to get a reading below about 60 degrees (the same as your car). The resistance or voltage (depending on the sender fitted) changes depending on the coolant temperature. The sender is used to give a reading of engine temperature on the panel, but can also be used by a controller to shut down at a specified temperature. The Switch, often supplied by the engine manufacturer is used to shut down the engine in the event of the coolant becoming too hot.
