5 Signs of Problems in Fleet Trucks

Did you know many fleets have an annual maintenance check on their trucks?

Fleet vehicles give businesses the ability to transport goods and people around. But, they also need maintenance because they run on engines that need intensive care. With regular check-ups and proper attention, these trucks can be efficient. Not to mention that they may endanger the lives of their drivers and passengers.

Luckily, there are signs of vehicle problems in fleet trucks. Keep on reading to learn what they are!

1. Rough Idle

If a fleet truck’s engine is causing a rough idle, this may be due to a faulty oxygen sensor or a worn spark plug.

It can also be because of misfiring cylinders, or a wasted ignition coil. Depending on the severity of the issue, the fleet driver may also notice a vibration in the fleet truck’s cabin when the engine is running.

Clogged fuel filters can also cause a rough idle, worn fuel injector, fouled spark plugs, or a dirty throttle body. Ignoring these signs can worsen the condition and lead to costly repairs.

2. Unexplained Jerking or Stalling

Jerking could state an engine misfire or a transmission problem. It leads to stalling if not addressed well. Diagnosing the cause of jerking or stalling can be easier with the help of a qualified mechanic.

Factors such as the age of the vehicle and its maintenance history need to be taken into account. That’s why you should do regular fleet vehicle maintenance, such as oil changes and filter replacements. Doing so can reduce the risk of problems with the fleet vehicle.

3. Excessive Noise

The engine may run too close to the redline, or the muffler may need attention. Abnormal loud exhaust noises are a significant issue. It is due to worn parts, incorrect fitting of aftermarket parts, loose parts, or accumulated carbon build-up.

The issue may lie in the drivetrain components, such as a worn Universal Joint or a worn differential bearing. These components will produce a growl or whine at certain speeds or when turning. You can hear a grinding noise if the brake pads are worn.

4. Oil Leakage

If a fleet truck loses oil, the engine and other vehicle parts can overheat. It causes extensive damage that requires expensive repairs.

An oil leak can also be hazardous, with oil slicks forming on the roads that can be a risk to nearby motorists. For the oil to be replenished appropriately, you must check it often and refill it as needed.

5. Strange Odors or Smoke

The smell of burning oil, exhaust fumes, and other odors can show that something is wrong. Burning oil could mean something simple like an oil leak or a severe engine malfunction.

Exhaust odor from the hood can state a problem with the exhaust system. While a smoky exhaust system can show an oversized load or needs attention to the muffler.
