Overheating Truck Engine: Causes and Solutions

Anh Tuan, a Hyundai truck driver on the Hanoi – Son La route, pulled over at a roadside stall in Hoai Duc district with a worried look on his face. His delivery was delayed because his Hyundai truck was “acting up” – the engine temperature had suddenly spiked.

“It must be the cooling system again, another day lost,” he sighed.

Engine overheating is a nightmare for any driver, especially those who regularly transport heavy loads like Anh Tuan. So, what causes this problem and how can it be fixed? Let’s explore with Hanoi Trucks!

Causes of Engine Overheating

High engine temperature can stem from various causes, ranging from simple to complex. Here are some common culprits:

• Low Coolant: This is the most common cause. Coolant absorbs excess heat from the engine, ensuring stable operation. When coolant is low, the engine overheats quickly.
• Clogged Cooling System: A radiator, coolant hoses, or thermostat clogged with dirt and debris can obstruct coolant flow, leading to overheating.
• Faulty Cooling Fan: The cooling fan cools the radiator, allowing the coolant to dissipate heat. A malfunctioning fan reduces cooling efficiency, causing the engine to overheat.
• Malfunctioning Water Pump: The water pump circulates coolant through the system. A faulty pump prevents coolant circulation, leading to overheating.
• Poor Quality or Low Engine Oil: Engine oil also helps dissipate heat. Using low-quality oil or running low on oil reduces engine efficiency and generates more heat.
• Overloading: Exceeding the vehicle’s weight capacity forces the engine to work harder, generating excessive heat and leading to overheating.

What to Do When Your Engine Overheats

• Do Not Continue Driving: If you notice your engine overheating, pull over to a safe location and turn off the engine.
• Do Not Open the Radiator Cap While the Engine is Hot: Opening the radiator cap while the engine is hot can cause scalding hot coolant to erupt, resulting in serious burns.
• Call for Roadside Assistance or a Qualified Mechanic: Avoid attempting DIY repairs if you lack the necessary knowledge and experience.
