Common Issues that Cause Semi Trucks to Overheat

Overheating in semi trucks is a serious issue that can lead to significant engine damage and costly repairs. Understanding the common causes of overheating can help prevent this problem and keep your truck running efficiently. At Florida Semi Truck & Trailer Repair, we provide expert big rig cooling system repair in Central Florida. Here are four common causes of semi truck overheating.
Low Coolant Levels
Coolant plays a vital role in regulating your truck’s engine temperature by absorbing heat and dissipating it through the radiator. If coolant levels drop due to a leak or lack of maintenance, the engine will overheat as it can no longer be cooled effectively. Regularly checking and maintaining proper coolant levels is key to preventing overheating.
Faulty Thermostat
The thermostat in a semi truck’s cooling system regulates the flow of coolant to the engine. When the engine reaches a certain temperature, the thermostat opens to allow coolant circulation. A malfunctioning thermostat might get stuck in the closed position, preventing the coolant from flowing through the engine, which leads to overheating. Replacing a faulty thermostat is a relatively simple fix that can prevent serious engine damage.
Clogged or Damaged Radiator
The radiator is essential for releasing heat from the coolant. As the miles add up, debris and grime can accumulate in the radiator, reducing its efficiency and causing the engine to overheat. Also, physical damage can prevent the radiator from working properly. Cleaning or repairing the radiator will help ensure that heat is effectively dissipated, keeping the engine cool.
Water Pump Failure
The water pump is responsible for circulating coolant throughout the engine and radiator. If the water pump fails or becomes inefficient due to wear and tear, it will no longer be able to move coolant through the system, causing the engine to overheat. Regular inspections of the water pump can help identify early signs of failure, such as leaks or unusual noises, allowing for timely repairs.
