Diesel engines are known for their durability and efficiency, which makes them a popular choice for commercial trucks. These trucks endure a lot of wear and tear, and regular maintenance is crucial for ensuring their longevity and optimal performance. That’s why we’ve put together a detailed checklist for maintaining diesel engines on commercial trucks and where to get professional commercial truck repair services.

Check the Oil

Oil plays a critical role in the smooth functioning of your diesel engine. It lubricates moving parts, reduces friction, and helps to dissipate heat. Here’s how to check the oil on your commercial truck:

  1. Park the truck on level ground.
  2. Turn off the engine and wait at least 10 minutes for the oil to settle.
  3. Pull out the dipstick, wipe it clean, and reinsert it fully.
  4. Pull out the dipstick again and note the oil level. It should be between the “MIN” and “MAX” markers.
  5. Inspect the oil for consistency and color. It should be smooth and not too thick, with a dark brown or black hue.
  6. If the oil level is low or the oil appears dirty, plan an oil change with a trusted professional like C&M Motors.

Review the Coolant Level and Strength

Coolant is vital for maintaining the engine’s temperature and preventing overheating:

  • Ensure the engine is off and cool to the touch.
  • Locate the coolant reservoir and inspect the fluid level. It should be between the “MIN” and “MAX” markers.
  • If the coolant level is low, top it up with the appropriate coolant mixture (usually a 50/50 mix of coolant and distilled water).
  • Periodically, test the coolant strength with a hydrometer or refractometer. This ensures that the coolant is providing adequate freeze protection and corrosion resistance.

 Is the Air Conditioning Working?

A functional air conditioning system is essential for driver comfort and safety. Here’s how to check your truck’s air conditioning:

  1. Start the engine and turn on the air conditioning to the highest setting.
  2. Check the airflow and temperature at the vents. The air should be cool and consistent.
  3. Listen for any unusual noises, such as grinding or squealing, which could indicate a problem with the compressor or fan.
  4. If the air conditioning isn’t working correctly, schedule an inspection with a professional technician.

A Comprehensive Engine Check

Regular engine checks are crucial for catching potential issues early:

  • Inspect the belts for signs of wear, such as cracks or fraying. Replace them as needed.
  • Check the hoses for any leaks, cracks, or bulging.
  • Look for signs of fuel, oil, or coolant leaks around the engine.
  • Inspect the air filter and replace it if it’s dirty or clogged.
  • Check the exhaust system for damage or leaks.
  • Inspect the battery for corrosion and ensure the connections are tight.

Full Tire Checks

Properly maintained tires ensure safety and fuel efficiency:

  1. Check the tire pressure with a reliable gauge. Inflate or deflate tires as needed to match the manufacturer’s recommendations.
  2. Inspect the tires for uneven wear, cuts, punctures, or bulges.
  3. Check the tread depth with a tread depth gauge. Replace tires if they’re below the minimum tread depth specified by the manufacturer.
  4. Inspect the wheel alignment and balance to prevent uneven tire wear and potential steering issues.
