Don’t Ignore these Symptoms of Semi Truck Cooling System Trouble

A semi truck’s cooling system plays a vital role in maintaining proper engine temperature during long hauls and heavy-duty operations. When the cooling system begins to fail, the engine is at risk of overheating, which can lead to serious mechanical damage and costly repairs. Spotting early signs of trouble can help prevent major problems and keep your rig safely on the road. At Cross Diesel Repair, we provide expert semi truck cooling system repair in the greater Corinth, KY area. Here are four common signs of a semi truck cooling system issue.
Rising Engine Temperature
One of the most obvious signs of a cooling system issue is a steadily rising engine temperature. If your temperature gauge starts creeping into the red zone, it’s a clear indication that the engine isn’t being properly cooled. This could be due to problems like low coolant levels, a failing water pump, or a clogged radiator. Continuing to drive with an overheating engine can lead to engine failure, so it’s important to address this issue immediately.
Coolant Leaks
Puddles of coolant under the truck or visible drips around hoses and fittings often point to a leak in the cooling system. Leaks can come from locations such as a damaged hose or a cracked radiator. Even a small leak can cause the coolant level to drop over time, reducing the system’s ability to manage engine heat. Detecting and fixing leaks early can prevent more extensive and expensive damage.
Low Coolant Warning Light
If your dashboard displays a low coolant warning, it’s a sign that the system isn’t full enough to operate efficiently. This could be caused by a leak, and ignoring it can lead to overheating. Topping off the coolant may solve the immediate issue, but it’s essential to identify the root cause to avoid future problems.
Steam from the Engine Compartment
If you see steam rising from under the hood, it could mean the engine is overheating and the coolant is boiling. In this situation, it’s best to pull over safely, shut off the engine, and allow it to cool before investigating further. Driving with a steaming engine can cause severe internal damage in short order.
