A semi truck’s cooling system plays a vital role in preventing the engine from overheating. Given the heavy loads and long hours these trucks endure, the cooling system is put under significant stress. If it malfunctions, the engine could overheat, leading to costly repairs and potential breakdowns. Recognizing the signs of cooling system trouble early can help prevent major issues on the road. At Kaos Truck & Trailer Repair, we provide expert roadside semi truck cooling system repair in Southern Nevada. Here are four common cooling system problems that semi truck drivers should watch out for.

Coolant Leaks

Coolant leaks are among the most frequent cooling system problems in semi trucks. These leaks can occur in locations such as hoses, the radiator, and the water pump. When coolant levels drop too low, the engine can quickly overheat, leading to severe damage. Drivers should regularly inspect their truck for puddles of coolant under the vehicle. Promptly repairing leaks can prevent costly engine damage.

Faulty Water Pump

The water pump is responsible for circulating coolant through the engine and radiator. If it fails, the coolant won’t move efficiently, causing the engine to overheat. Common signs of a failing water pump include coolant leaks around the pump, unusual whining noises, or fluctuating engine temperatures. Since a malfunctioning water pump can lead to engine failure, it’s essential to replace it as soon as issues arise.

Clogged or Damaged Radiator

The radiator is critical for dissipating heat from the engine, but it can become clogged with debris over time. A clogged radiator restricts coolant flow, leading to overheating. External damage can also reduce the radiator’s efficiency. Drivers should inspect the radiator for visible signs of damage and ensure it remains clean and free of obstructions. Regular flushing of the cooling system helps prevent buildup inside the radiator, keeping it functioning properly.

Malfunctioning Thermostat

The thermostat regulates coolant flow. If it gets stuck in the closed position, coolant won’t circulate properly, causing the engine to overheat. Conversely, if it’s stuck open, the engine may run too cold. Erratic temperature gauge readings are a sign of a thermostat problem. Replacing a faulty thermostat can prevent more significant cooling system problems.
