Heavy duty diesel parts can last a long time if well cared for. That’s why summer diesel engine maintenance is important. Without that, breakdowns can happen, and a lot of earnings may be lost.
Luckily, summer diesel engine maintenance involves mostly a lot of common sense.
Diesel Engine Heat Protection
Summer heat is the primary consideration while maintaining your diesel engine during the next few months. Focus on coolant and overheating prevention.
Working with Coolant
- Ensure proper coolant levels and concentration (usually a 50/50 mix of coolant and water).
- Apply a coolant flush every two years or as per your manufacturer’s recommendations.
- Inspect hoses for leaks or bulges.
- Clean radiator and condenser fins to maintain airflow.
- Check the radiator cap pressure rating.
- Use a thermal gun to check for proper heat transfer from the coolant to the radiator.
Overheating Prevention
Regularly monitor your engine temperature gauge. If the temperature begins to exceed the manufacturer’s recommended range, revisit the cooling system steps outlined above. Always use a high-quality coolant and promptly replace any worn or leaking hoses.
Mineral buildup inside the radiator can block coolant flow and impair heat dissipation. A complete system flush can typically resolve this issue.
Check the radiator for cold spots, which may signal restricted airflow or trapped air pockets. If air is present in the system, bleeding the radiator can help restore proper circulation.
Ensure the cooling fan operates as intended. It should engage automatically at the designated temperature. Also, verify that the fan shroud is properly in place and that airflow isn’t obstructed, especially at higher speeds.
Double Check Airflow Through the Radiator
Make sure the air intake for the radiator isn’t blocked. Use an anemometer to measure air velocity through the radiator and calculate airflow. If you’re having trouble pinpointing the problem, a manometer can measure the pressure difference across the radiator.
Lubrication
A poorly lubricated engine is going to heat up faster. It will also cause the parts to wear out more quickly. This combination adds up to double trouble in the summertime.
Keeping your rig well lubricated is the solution.
- Follow the manufacturer’s oil change schedule.
- Use the recommended oil grade and viscosity.
- Consider synthetic oils for better thermal stability.
- Use a fuel additive for better lubrication and keeping the system clean.
- Drain the fuel/water separator daily.
Air Filters
Air filters are essential for protecting your engine from dust, dirt, and debris. By keeping contaminants out, they help preserve engine performance, boost fuel efficiency, and extend the life of your engine.
Inspect and replace air filters regularly; especially in dusty environments or when filters appear dirty or clogged.
If you suspect your heavy-duty diesel engine needs a new part, trust your instincts. Timely replacements help avoid bigger issues down the road and keep your rig running strong.
