For maintenance managers overseeing modern workshops, understanding and implementing proper fluid maintenance protocols is crucial. These essential procedures extend vehicle life span and significantly reduce operational costs.

Whether handling a small fleet or large-scale operation, these tips will help optimize your fluid management procedures to maintain peak vehicle performance.

1. Learn What Each Fluid Does
Heavy-duty trucks rely on several fluids to operate effectively. Each serves a unique function and purpose:

• Engine oil: Lubricates engine components, reducing friction and preventing overheating.
• Coolant (antifreeze): Regulates engine temperature and discourages corrosion within the cooling system.
• Brake fluid: Transmits force from the brake pedal to the braking mechanism, guaranteeing reliable stopping power.
• Transmission fluid: Lubricates and cools the transmission system, ensuring smooth gear shifts and reducing wear.
• Power steering: Enables easy steering by lubricating and pressurizing the power steering system.
• Differential oil: Protects the gears in the differential from friction and heat, ensuring smooth operation.
• Fuel system additives: Improve fuel efficiency and engine performance while reducing carbon deposits.
• Windshield washer fluid: Cleans the windshield and improves visibility during adverse conditions.

Understanding what these fluids do makes it easier to know why checking them is vital.

2. Use High-Quality Fluids
Cheap fluids might save money initially, but they can cause more damage over time. For instance, using high-quality synthetic oils in heavy-duty trucks can provide longer service intervals, stretching your oil change interval to 10,000 miles.

Always follow the truck manual to pick fluids that work best for your vehicles. Also, ensure the new fluids won’t react badly with what’s already in the system.

3. Invest in Technology
Modern tools can help you track fluid levels and quality. Some workshops use systems that monitor fluids in real time, so they can fix problems before they cause breakdowns.

These tools save time and reduce errors. Sensors can send alerts when fluids need attention. GPS and telematics systems can also track fluid usage patterns, helping managers plan better.

4. Check Your Fluids Regularly
To keep trucks running their best, you must routinely check the fluids. Regular checks can catch problems like dirt or low levels before they lead to bigger issues.

Brake fluid is especially important for safety. Experts recommend checking it often to ensure the levels stay within the proper range. Low brake fluid can lead to brake failure. Use simple tools like dipsticks or automated systems in your workshop to make these checks quick and accurate.

Sticking to a schedule for checking and changing fluids keeps everything running smoothly. Make a checklist to ensure all fluids are checked and replaced when needed. Some companies use software to send reminders for fluid replacement schedules, ensuring no deadlines are missed.

5. Keep Good Records
Write down everything you do with your truck fluids, like when they were checked or changed. These records can help you spot patterns, plan maintenance and prove that you follow industrial rules.

Keeping these records using software can make the process faster and more organized. Develop a digital tracking system that monitors fluid consumption patterns, change intervals and analysis results. This data helps identify trends like increased coolant usage during summer months. You can also use it to optimize maintenance schedules across your fleet.

6. Dispose of Used Fluids Safely
Old fluids need to be thrown away carefully. This is important for protecting the environment, your company and your reputation. Establish clear steps for collecting and safely disposing of waste fluids in the workshop.

Work with recycling companies that uphold eco-friendly initiatives and handle disposal correctly, such as Shell Eastern Petroleum, which acquired EcoOils — a waste oil recycling firm in Southeast Asia. This approach complies with regulations while also supporting sustainable operations.

7. Train Your Team
Your team plays a significant role in fluid management. Training helps prevent mistakes, keeps trucks in top condition and helps your workshop personnel stay current with evolving fluid management technologies.

Teach them to spot signs that a fluid needs to be changed or topped up. They should also know how to handle fluids safely. Invest in regular training sessions on proper sampling techniques, contamination control and fluid analysis interpretation. Organizing regular workshops or bringing in industry experts can boost your team’s knowledge and skills.

8. Adjust for Local Conditions
Trucks face different challenges depending on where they’re used. Adjusting your fluid management to fit local conditions helps your trucks stay reliable and last longer.

For example, hot weather in tropical Malaysia or Thailand can cause coolant to evaporate faster, so it might need to be checked more often. In colder Russia, antifreeze becomes nonnegotiable, as does de-icing windshield wiper fluid to melt and prevent ice from adhering to the glass. Trucking companies in Central Asian southern desert regions may need to implement stricter schedules for inspecting air filters and coolant systems.
