Generators have become a must-have in almost all industries today. Having one is a big investment, and for this reason, regular maintenance is vital. There are different types of generators available today, and the one you choose should align with your needs.

Some of the generator’s maintenance processes involve checking the coolant level, oil level, charger-air cooler piping and hoses, fuel system, and starting system.This article articulates the essential maintenance tips for a diesel generator that guarantees an uninterrupted power supply at all times. Read on to find out more.

  1. Observe a routine general inspection 

The first thing that you will need to do is to observe a general inspection routine. When a diesel generator runs, the exhaust system, fuel system, DC electric system, and the engine should be constantly monitored for any leak. One of the best practices is to change the oil after every 100 hours of operation. 

        2. Maintain a consistent lubrication service

Besides changing the oil after certain intervals, the engine oil must be checked while shutting down the generator. Use a dipstick to keep the oil level as near as possible to the full mark. Ensure that you use high-quality oils, lubricants, and coolants to keep the engine working.Find out more on how to drain the oil and replace oil filters from the manufacturer of the generator.

  1. Check the cooling system during shut down

Diesel generators, especially the heavy-duty engine type, require a balanced coolant mixture of water, antifreeze, and coolant additives. Once the engine is cool, remove the cap, and if necessary, add the coolant until a ¾ level. Clean the radiator that removes dirt or foreign material that might be trapped. To do this, use a soft brush or a cloth to avoid damaging the fins. 

  1. Check the testing system

To avoid any start-up hitches of the generator, it is imperative to know the current status of the battery. The battery should be fully charged and cleaned regularly by wiping it with a cloth whenever dirt appears excessive. Ensure the specific gravity and electrolyte levels of the battery are checked frequently. For some generators, the terminal voltage is measured automatically, whereas, for others, a manual battery load tester is used.

  1. Inspect the exhaust system

Another way to maintain a diesel generator is to inspect the exhaust system in case there are leakages along the exhaust line. Leaks usually occur at the connection points, the welds, and the gaskets.To avoid any leaks, ensure the units are correctly serviced. It is recommended to do so 24hrs before using a diesel generator.


Do you have a problem maintaining a diesel generator? Now that you have gone through this piece, you can take the necessary steps to ensure that your generator is in good condition at all times. However, if your generator has a re-occurring fault that seems hard to deal with, seek professional help from a technician, or you can consult the manufacturer for further assessment.
