Semi trucks are essential for transporting goods across long distances, but they are also prone to overheating due to the heavy loads they carry and the long hours they run. Overheating can cause significant damage to the engine and other components, leading to costly repairs and downtime. When you first notice that your big rig is overheating, it’s important to take action. At Kaos Truck & Trailer Repair, we provide expert roadside semi truck cooling system repair in the greater Las Vegas area. Here’s a look at four common reasons that semi trucks overheat.

Coolant Leaks

Coolant leaks are one of the most common causes of overheating in semi trucks. Leaks can occur in various parts of the cooling system, such as the radiator, hoses, and water pump. When coolant levels drop, the engine cannot maintain the optimal temperature, leading to overheating. Regularly inspecting the cooling system for leaks and maintaining proper coolant levels can prevent this issue.

Faulty Radiator

The radiator is a crucial component of the cooling system, responsible for dissipating heat from the engine. As the miles add up, radiators can become clogged with dirt and debris, reducing their efficiency. A faulty radiator fan can also contribute to overheating, as it fails to draw enough air through the radiator to cool the coolant. Routine maintenance, such as flushing the radiator and ensuring the fan operates correctly, can help prevent overheating caused by radiator issues.

Thermostat Failure

The thermostat regulates the flow of coolant between the engine and the radiator. When the engine reaches a certain temperature, the thermostat opens to allow coolant to flow and cool the engine. If the thermostat fails to open or becomes stuck, the coolant cannot circulate properly, causing the engine to overheat. Replacing a faulty thermostat is a relatively simple repair that can prevent severe engine damage.

Overloaded Engine

Semi trucks are designed to carry heavy loads, but overloading the engine can lead to overheating. When a truck is overloaded, the engine has to work harder to move the vehicle, generating more heat in the process. This increased strain can overwhelm the cooling system, especially if it is not in optimal condition. Ensuring that the truck is not overloaded and adhering to weight limits can help prevent overheating and extend the life of the engine.
