4 Semi Truck Cooling System Issues that Should Be Resolved ASAP

A semi truck's cooling system is vital to keeping the engine running at a safe temperature, especially during long hauls and under heavy loads. When cooling system issues arise, they can quickly escalate into serious problems. At Florida Semi Truck & Trailer Repair, we provide expert semi truck cooling system repair in Central Florida. Here are four common big rig cooling system issues that should be promptly addressed.
Radiator Problems
The radiator plays a central role in dissipating heat from the engine, and any issue with it can cause big trouble. Corrosion, internal clogs, or external damage from road debris can reduce the radiator’s efficiency. If the engine begins to overheat or the radiator fins are visibly damaged, the truck should be serviced as soon as possible.
Coolant Leaks
One of the most frequent cooling system problems is a coolant leak. These leaks can develop in locations such as hoses, the radiator, and the water pump. Low coolant levels reduce the system’s ability to regulate engine temperature, which can lead to overheating and engine failure. Any sign of coolant puddles under the truck or a consistently low coolant reservoir should prompt immediate inspection.
Faulty Thermostat
The thermostat regulates coolant flow through the engine based on temperature. If the thermostat fails in the closed position, it can prevent coolant from circulating, causing the engine to overheat quickly. If it’s stuck open, the engine may run too cool. Fluctuating engine temperatures are a sign that the thermostat may be malfunctioning and needs to be replaced.
Water Pump Failure
The water pump is responsible for circulating coolant through the engine and radiator. When the pump begins to fail due to worn bearings, impeller damage, or seal leakage, the coolant flow becomes inadequate. This can lead to overheating and potential engine damage. A whining noise is a common warning sign that should be checked by a mechanic right away.
