In the fast-paced world of trucking, ensuring your vehicle remains in optimal condition is crucial for both safety and efficiency. The last thing you want is an unexpected breakdown to disrupt your schedule, costing time and money.
So, how can you prevent the risks of sudden breakdowns? Short answer: by sticking to a consistent preventive maintenance method. Here are four maintenance tips you can use to minimize unexpected repairs and maximize your uptime.
1. Tires
Tires play a major role in keeping you safe and moving. Before heading out, always check for the following:
- Tire pressure: Underinflated and overinflated tires are more susceptible to blowouts and uneven wear. Check your owner’s manual for the optimal pressure for your tires.
- Damage: Check the rubber on each tire for any objects, cuts, abrasions or exposed steel. Make sure the lug nuts, valve caps and valve stems are all in good condition as well.
2. Fluids
If you’re headed out for a long haul, it’s essential to check the levels before you leave. This ensures your engine will have the fluids it needs to perform properly, reducing your risk of unexpected breakdowns. Be sure to check the following:
- Coolant: Coolant condition should be checked on average every 30,000 - 35,000 miles*. Inspect your coolant for discoloration (black, dark brown or cloudy) and debris. Ensure you have the right amount of coolant daily by looking for the markings on the side of the reservoir. If the level is low, add more coolant.
- Engine oil: This should be changed on average every 60,000 to 75,000 miles for heavy duty linehaul applications*. Make sure the oil has a smooth consistency, free of dirt or rough deposits. If it appears to show these signs, it’s time for service. If the oil level is overfull, check to see if it has a milky appearance, indicating the presence of coolant, or thinned out and smells like fuel. Both of these conditions could indicate a more serious problem with your engine and need to be addressed.
- Transmission fluid: Check the level of the fluid using the dipstick if your truck has one. Otherwise, visit your local MHC service department to do a thorough check. Low levels of transmission fluid need to be addressed immediately.
*Types of fluids and fluid levels vary by truck and application. Always check your owner’s manual or visit your local MHC dealer to ensure your truck is has the proper fluids.
3. Electrical Systems
Batteries and alternators play a major role in providing your truck with the power it needs to operate its best. Any issues with the electrical systems can limit the truck’s performance and significantly increase the chances of a breakdown. You should check for the following:
- Battery life: Ensure the battery is fully charged and has the recommended capacity for your truck.
- Cables and wires: Ensure the cables and wires are clean, intact and free of damage.
4. Brakes
Moisture buildup in the air system can cause damage and improper operation of the air brake system. It’s recommended to drain moisture from supply and service air tanks daily. If you find an excessive amount of water, it could mean it’s time to change your air dryer cartridge.
Preventative maintenance can keep you moving for longer, increase your uptime and keep you safe. Schedule a service appointment at your local dealer to have one of MHC’s certified technicians do a thorough check of your truck and keep you road ready!
