About Cummins Fleetguard

Fleetguard Cooling Systems


Benefits of Using Cummins Genuine Products

Optimised performance

Today’s engines are more sensitive to microscopic contamination and water due to higher injection pressures and tighter tolerances. Every Fleetguard product is developed and tested in conjunction with the base engine package to ensure optimal performance by enhancing combustion and power while minimizing engine wear.

Increased Uptime

Higher power density, changes in oil formulations and exhaust gases cause higher production of soot and sludge in oil which increases engine wear. We provide the best technology for maximum filtration efficiency, minimal flow restriction, extended service intervals and optimal filter life.

Enhanced Fuel Economy

Fleetguard products maximize fuel efficiency by removing smallest contaminants; maintaining appropriate coolant flow rates, enhancing fuel lubricity, and lowering soot by 40% over the service interval. Our lightweight and smaller products, like our User-Friendly Filters, reduce fuel costs during transport.

Lower Operating Costs

When engine systems are properly maintained with Fleetguard products for normal and extended

service intervals, overall operating costs decrease, including acquisition, installation and removal, inventory, transaction and disposal costs.

Environmental Safety

Fleetguard products support customers in meeting global emission regulation standards by lowering exhaust emissions, extending service intervals and reducing hazardous waste.

Maintenance Contracts

Why should you have an Annual Maintenance Contract for your Cummins Power Generation diesel generator?

All machines require regular and timely care and maintenance; especially moving parts need periodic cleaning, lubrication and adjustment. It’s equally important to identify and correct faults before they develop into component failures, which are costly and time consuming to repair.

We offer our customers the opportunity to ensure that their diesel generator operates to its potential. Our aim is to provide you with world-class service support that is fast and responsive, flexible and convenient. Annual Maintenance Contracts (AMCs) are the most effective & efficient way of ensuring your diesel generator receives the timely care it needs and performs at its peak. AMCs reduce operating costs by extending the useful life and increasing reliability and maximum productivity of your generator.

What are the advantages of going for an Annual Maintenance Contract?

  • Allows you to benefit from better prices compared to customers without AMCs
  • Reduces risk, disruption and loss of revenue caused by unscheduled power outages by 
ensuring your generator is always ready to start and deliver power
  • Helps you to concentrate on your core business
  • Ensures increased uptime, leading to greater productivity and increased revenue
  • Delivers early warnings and enables prompt action
  • Gives you the opportunity to plan ahead with greater confidence
  • Helps us plan ahead and serve you better

Can’t I have my neighborhood handyman do the job for me?

We use highly skilled Cummins-certified technicians and genuine Cummins spare parts with Fleetguard filters. Our repairs carry a guarantee. When you buy spares from us you receive a genuineness certificate from Cummins. Now that you’ve invested good money buying one of the best products in the world, why not treat it right and ensure it delivers what was promised?

How often must I service my diesel generator?

Every 250 hours or 6 months, whichever occurs first. During each service, our technicians will inspect the generator’s lubrication system, coolant system, electrical system, air intake system, exhaust system and control system. They will change oil filters, fuel filters, coolant filters and engine oil. Maintenance recommendations will be provided in line with Cummins guidelines.

What’s the difference between a service and an inspection?

Lubrication & coolant systems, electrical, air intake, exhaust and control systems are checked during an inspection to ensure that your diesel generator is healthy. Oil & filter change is NOT included.

What are my options?

Option 1: Comprehensive AMC (2 services per year + 2 inspections per year)
Highly Recommended. With a Comprehensive AMC, potential problems can be identified early and preventive measures can be employed. You can achieve increased operational efficiency, reduced risk of generator downtime and complete control over costs.

Option 2: Basic AMC (2 services per year)
Recommended. You have most of the benefits of a Comprehensive AMC but there will be a 6-month gap between our visits.

Option 3: Custom AMC (example – 1 service per year + 1 inspection per year)
You have the flexibility to tailor this package to your unique requirement. You may include or exclude any elements from the other AMCs to suit your operational needs and budget. You may even opt for inspections only. There is an element of risk here because the performance characteristics of oil change with time.
