Summer Maintenance Checklist for Diesel Generators

As summer approaches, there’s no better time to handle critical maintenance tasks for your diesel power system. After all, this season is more prone to experiencing power failures than others due to increased energy demand, summer-related storms, and uncontrollable wildfires. However, extreme temperatures can result in various issues for a generator if it’s not serviced according to the recommended maintenance schedule. High ambient temperatures can lead to overheating, battery malfunctions, reduced efficiency, electrical issues, and even complete generator failure. Diesel Generator Maintenance

The last thing you want during a power outage is a malfunctioning generator. If you experience a prolonged outage without a reliable backup power system, you risk significant financial losses, jeopardizing your business. Stay powered up this summer by following this essential maintenance checklist from Valley Power Systems.

Perform a Visual Battery Inspection

Having a properly functioning diesel generator battery is crucial for ensuring consistent system performance. We recommend performing a visual battery inspection each summer. Take a look at the battery and terminals, and tighten up loose connections as needed. If you notice any rust or corrosion, you should have one of our trained technicians address it right away. Even minor corrosion can interfere with the battery’s performance, potentially leading to power fluctuations and unexpected failures.

You should keep in mind that diesel generator batteries are only designed to last 2 to 3 years, similar to car batteries. If your battery has exceeded this time frame, you may want to consider replacing it to maintain system reliability for your business.

Clear Air Filters

Your generator’s air filters can quickly become clogged with dirt, dust, and debris, especially during summer storms. Clogged filters will reduce airflow, forcing the generator engine to work much harder than usual. This excess stress can lead to a host of problems, including efficiency loss, overheating, and generator failure. These issues often result in a shortened lifespan for a diesel generator.

At Valley Power Systems, we recommend clearing air filters at least once a month and replacing them altogether once they begin to appear dirty. You should also check them immediately after a major weather event, such as high wind or heavy rain, which can stir up additional debris in the air. Replacing air filters regularly will help minimize wear on engine components and keep your diesel system in good working order.

Clean the Generator Area

You shouldn’t overlook the cleanliness of the generator’s surrounding area. Regularly picking up around the diesel generator will go a long way toward reducing filter clogs and maximizing system lifespan. Be sure to check the area around the generator at least once a week for excessive dust, debris, or trash that could get picked up by your generator vents.

It’s also a good idea to ensure the exterior of your unit is clean. You can wipe it down with a soft cloth, but avoid spraying any water directly on the unit, as moisture exposure can lead to severe engine damage. If the exterior is excessively dirty, reach out to our team at Valley Power Systems to schedule a professional generator cleaning. Our technicians have the proper equipment, tools, and knowledge to thoroughly clean your diesel generator without damaging the system.

Top Off Coolant

Keeping your cooling system in prime condition is key to extending the lifespan of your diesel generator. Keep an eye on the unit’s coolant levels this summer and top off as needed. However, if you notice any issues that could be related to your cooling system, it’s best to schedule a professional inspection from Valley Power Systems. Some of the most common signs of cooling system problems include:

High engine temperature
Coolant leaks
Malfunctioning cooling fan
Discolored coolant
Reduced generator performance

Our skilled team will be able to determine the source of the issue and provide a prompt repair, ensuring that your system is ready to go when you need it most.

Check for Leaks

Over time, diesel generators can develop oil, fuel, or coolant leaks. Left unaddressed for too long, these leaks can lead to overheating, reduced performance, or even engine failure. Regular visual inspections are key to spotting leaks early on and addressing repairs before the problem worsens. However, determining the exact location of a leak can be challenging on your own, so it’s best to work with a professional. At Valley Power Systems, our technicians have the expertise to identify hidden leaks and repair them promptly while you focus on your business.

Schedule an Oil and Filter Change

One of the most important tasks you can do for your diesel generator this summer is to schedule an oil and filter change with Valley Power Systems. Fresh oil will keep the moving parts and components of your generator engine nicely lubricated, reducing friction and overall wear and tear. Well-maintained filters will also maximize oil performance, keep the engine clean, and prevent premature repairs. At Valley Power Systems, we recommend changing filters with every oil change to promote a long system lifespan.
