Generator TLC: Keep Your Powerhouse Running Smoothly

Essential Maintenance Tips for Long-lasting Diesel Generators

When your business relies on backup power, a diesel generator is more than just equipment, it’s your safeguard against downtime. Whether you’re running operations in a remote location, managing emergency power for a facility, or operating heavy machinery on a job site, your generator needs to be ready to perform at a moment’s notice.

At Gogopower, we understand that regular diesel generator maintenance is the key to long-lasting performance. Neglecting basic upkeep can result in costly repairs, performance issues, and unexpected outages. This guide covers everything you need to know to keep your generator in prime condition for years to come.

Why Diesel Generator Maintenance is Critical

Diesel generators are known for their durability, but even the most robust models require routine care. Over time, the combined effects of dust, moisture, and general wear can lead to:

• Decreased fuel efficiency
  

• Hard starts or failure to start
  

• Overheating due to clogged filters or coolant issues
  

• Carbon buildup and emissions problems
  

• Unexpected equipment breakdowns
  
  

By investing in consistent generator servicing, you not only extend the life of your generator but also reduce operating costs and avoid critical downtime, especially during peak usage periods.

Step One: Perform Regular Visual Inspections

Routine inspections allow you to catch potential issues early. Before every use—or at least weekly for standby units, conduct a visual check. Look for:

• Leaks around fuel, coolant, or oil lines
  

• Cracks or wear in belts and hoses
  

• Corrosion or loose connections on the battery terminals
  

• Dirt and debris buildup in vents or around the enclosure
  
  

Make inspection part of your maintenance routine by using a checklist. Tracking observations over time can help pinpoint patterns and plan preventative service with accuracy.

Stay on Top of Oil and Filter Changes

Oil plays a critical role in protecting the engine. But over time, it breaks down and collects contaminants that can damage internal parts. Sticking to a regular oil change schedule is one of the most effective ways to ensure long-term generator performance.

Recommended service intervals:

• Oil change: Every 100–250 operating hours or as per the manufacturer’s guidelines
  

• Oil filter: Replace during every oil change
  

• Air filter: Inspect and replace if dirty or clogged
  

• Fuel filter: Replace every 250–500 hours or when water or dirt is present
  
  

Pro tip: Always use high-quality oil and filters to match your generator’s specifications. At Gogopower, we can advise on the best products to match your generator model and use case.

Don’t Skip Load Testing

One of the most common mistakes generator owners make is letting the unit sit idle for long periods. This leads to carbon buildup and other issues that affect reliability.

Load testing, where the generator runs under full or near-full load, should be done regularly to keep the engine healthy and responsive.

Benefits of regular load testing include:

• Burning off excess carbon deposits
  

• Preventing fuel system blockages
  

• Maintaining engine lubrication
  

• Testing the system’s response under real-world conditions
  
  

Aim to run your generator at full load for 30–60 minutes at least once a month. This not only keeps the internal systems active but also builds confidence in your equipment when an outage strikes.

Maintain a Clean and Dry Environment

While it might seem like a cosmetic issue, cleanliness is essential to generator longevity. Dirt and grime can block vents, trap heat, and lead to corrosion or even fire hazards.

Maintenance tips:

• Wipe down the exterior of the unit to remove dirt and grease
  

• Check for pooled water or signs of rust inside the enclosure
  

• Make sure the generator sits on a stable, level surface away from vegetation and debris
  

• Inspect electrical components for dust, insects, or moisture
  
  

If your generator operates in harsh or humid conditions, consider housing it in a weather-resistant enclosure. Gogopower offers units with built-in protection designed for Australian conditions.

Fuel Management: Keep It Fresh

Diesel fuel can degrade over time, especially in warm or humid climates. Stale or contaminated fuel leads to clogs in the injectors and poor combustion.

To keep your fuel in good condition:

• Rotate fuel stock every 6–12 months
  

• Use stabilisers if storing fuel long-term
  

• Drain water from the bottom of the fuel tank or water separator regularly
  

• Keep storage tanks sealed to avoid condensation and microbial growth
  
  

High-quality fuel ensures that your diesel generator runs cleanly and efficiently—and reduces the need for injector cleaning or filter replacement.

Pay Attention to Your Battery System

The battery is one of the most overlooked components in diesel generator maintenance. Without it, the generator won’t start, regardless of the fuel or mechanical condition.

To avoid battery-related issues:

• Inspect and clean battery terminals regularly
  

• Check voltage levels and charge if needed
  

• Test the battery every few months under load
  

• Replace older batteries every 2–3 years as a precaution
  
  

Many Gogopower generators are equipped with built-in battery monitors to help you stay ahead of issues before they impact operation.

Professional Servicing: Partner with Experts

While regular owner maintenance is crucial, nothing replaces the value of professional servicing. A trained technician can identify issues you might miss, and they’ll have the tools to conduct advanced diagnostics.

Professional diesel generator servicing should include:

• Full system diagnostics and performance checks
  

• Exhaust and emission system inspections
  

• Alternator testing
  

• Cooling system flushes and coolant top-ups
  

• Engine tuning and firmware updates (if applicable)
  
  

At Gogopower, we can provide servicing if required, however,, it is within the client’s responsibility to ensure a service is done at every 500 hours..

Final Thoughts: Give Your Generator the Care It Deserves

Diesel generators are a powerful asset for any business or industrial operation but only when maintained correctly. By adopting a structured maintenance schedule, you're not just protecting your investment; you're ensuring your generator is ready when you need it most.

From visual inspections to oil changes, load testing, and fuel quality management, every step you take now prevents costly problems later. For more information regarding maintenance, check out our generator FAQs page.
