Semi trucks play an integral role in the transportation industry, ensuring goods are delivered efficiently across vast distances. However, these trusty rigs are not immune to problems, and one of the more common problems is overheating. If your truck’s engine fails to stay sufficiently cool, you’ll want to alert an experienced diesel mechanic. At Blue Gray Towing, we provide expert semi truck cooling system repair in the greater Hagerstown, MD area. Here are four common causes of semi truck overheating.

Faulty Thermostats

The thermostat in a semi truck controls the flow of coolant through the engine, maintaining an optimal operating temperature. A malfunctioning thermostat can get stuck in either the open or closed position, disrupting the coolant flow. If the thermostat remains closed, the engine may overheat due to the lack of coolant circulation. Regular inspections and replacement of thermostats can prevent such scenarios.

Clogged Radiators

Radiators play a pivotal role in dissipating heat generated by the engine. As the miles add up, radiators can accumulate debris, dirt, and other contaminants, reducing their effectiveness. A clogged radiator impedes the airflow and prevents proper heat exchange, leading to overheating. Regular maintenance of radiators is important to ensure efficient cooling.

Malfunctioning Water Pump

The water pump is responsible for circulating coolant throughout the engine and the radiator. A malfunctioning water pump can disrupt this circulation, leading to uneven cooling and potential overheating. Regular inspections of the water pump, including checking for leaks or unusual noises, can help identify issues early on and prevent overheating.

Airflow Restrictions

Adequate airflow is crucial for keeping the engine cool, and any restrictions in the airflow can contribute to overheating. Issues such as a malfunctioning fan or obstructions in the air intake can impede the cooling process. Regular checks and maintenance of the cooling fan and associated components are important for ensuring optimal airflow.
