Semi trucks endure thousands of miles on the road, often hauling heavy loads across varied terrain. With this demanding workload, engine problems can inevitably arise. At Blue Gray Towing, we provide expert semi truck engine repair in the greater Hagerstown, MD area. Here’s a look at five common semi truck engine problems to look out for.

Overheating

One of the most frequent engine issues in semi trucks is overheating. This problem can occur due to low coolant levels, malfunctioning thermostats, or a damaged radiator. Semi truck engines are large and powerful, generating significant heat, especially during long hauls. Overheating can lead to serious engine damage if not addressed promptly.

Turbocharger Failure

Semi trucks commonly use turbochargers to boost engine power and improve fuel-efficiency. However, turbochargers are subject to high stress, leading to wear over time. A failing turbocharger can result in poor engine performance, decreased power, and excessive smoke from the exhaust.

Oil Leaks

Oil leaks are a common problem for semi truck engines, especially as they age. Leaks can occur due to worn seals, gaskets, or damaged oil pans. Left untreated, oil leaks can lead to low oil levels, causing increased friction and overheating, which can severely damage engine components.

Fuel Injector Problems

Fuel injectors are responsible for delivering the right amount of fuel to the engine. As the miles add up, they can become clogged or fail, leading to inefficient combustion, loss of power, or increased fuel consumption. Faulty fuel injectors can also cause the engine to run rough or misfire.

Faulty Sensors

Modern semi trucks are equipped with various sensors to monitor engine performance and emissions. Faulty sensors, such as oxygen or mass airflow sensors, can send incorrect data to the engine control module, resulting in poor engine performance.
