What are the key considerations to maintain generator sets in winter?

Generator Preventive Maintenance Checklist

Generator sets must undergo preventive maintenance to ensure that there are no unexpected errors or breakdowns while in operation. We highly recommend doing so both in summer and winter, and now with the arrival of cold weather, there are some factors that must always be taken into account. In this post, we would like to draw your attention to details that have to be checked carefully and rigorously for the winter that lies ahead. For this reason, our technical team has drawn up a generator preventive maintenance checklist for you. If you have an industrial generator set, we advise you to read on because if you follow the advice below, it will increase your generator set’s performance and lengthen its useful life.

Generators; maintenance and repair in winter

It is vital that the battery’s electrolyte level is checked regularly. This is an extremely important task as electrolytes are made up of distilled water and sulfuric acid.  Throughout the summer, it is very likely that the water will have evaporated and this would damage the battery and prevent the generator group from starting when needed.

Generator sets that have been installed in cold climates are fitted with a resistance that heats the antifreeze which circulates through the engine. This resistance has a thermostat that maintains the antifreeze at a temperature that ranges between 35º and 40º degrees.  You can check whether the resistance is working correctly by touching the top of the engine which should feel hot to touch. If it is cold, you should call the technical service immediately because you can cause damage to the engine if you start it at a very low temperature. Repairing this type of damage can be very costly.

It is also vitally important to check the coolant level. To check it, you have to remove the radiator cap from the engine. A word of caution; always check it when the radiator is cold and when the engine is not running.

If the coolant level is low, the resistance will not be able to heat all parts of the engine correctly. In fact, it could even burn the resistance itself, as it is not in contact with liquid.

You must top up the radiator with suitable coolant, but never with water. Likewise, it is important to notify the technical service team if you detect any leakage or any spotting from a possible coolant leak.

Thanks for taking the time to read our generator preventive maintenance checklist. We truly believe that corrective maintenance of generator sets today will save you time tomorrow.
