What Causes Truck Overheating and How to Deal with It?
2 Answers
Truck overheating common causes introduction: 1. Insufficient antifreeze in the engine cooling system: Possible engine leakage points such as water pump leakage, pipeline damage, radiator damage, etc. 2. Thermostat failure in the engine cooling system causing excessive water temperature: Because the thermostat cannot open, the flow of coolant inside the engine is obstructed, resulting in excessively high coolant temperature. 3. Malfunctioning cooling fan in the engine cooling system: Leads to poor heat dissipation of the coolant. Therefore, the water temperature warning light comes on, causing the coolant temperature to be too high. 4. Water pump failure in the engine cooling system: The water pump does not rotate smoothly, resulting in poor coolant flow, so the water temperature warning light comes on and the coolant temperature becomes too high.
When driving large vehicles on long-distance trips, I have encountered overheating issues multiple times. The main causes include cooling system failures such as radiator blockages or loose fan belts. I remember one time during summer on the highway, the water temperature suddenly rose, so I quickly pulled over to check and found that the coolant was insufficient, possibly due to a small leak. To handle it, I immediately added pure water as a temporary substitute for antifreeze and used my phone's flashlight to check if the belt was broken. If not resolved promptly, the engine could easily suffer from cylinder scuffing and damage. Prevention is crucial. Now, before every trip, I check the radiator and water pump, and regularly clean the radiator to avoid excessive load causing temperature spikes. In short, safety comes first—don't push through when overheating.
