Here we discuss how your heavy-duty truck's coolant system works, why your truck is overheating, and how to spot if your coolant system needs immediate attention.
Keeping your engine cool during use is crucial to the health and performance of your vehicle. Here we discuss how your heavy-duty truck's coolant system works, why your truck is overheating, and how to spot if your coolant system needs immediate attention.
How Does a Heavy-Duty Coolant System Work?
In simple terms, the coolant system is responsible for regulating the temperature of your truck's engine and preventing it from overheating. The coolant, a specially formulated mixture of antifreeze and water, circulates through the engine and acts as a vessel to transfer heat.
The heat from the engine is dissipated by the coolant, which is then transferred by the water pump to the radiator at the front of the truck, where the oncoming air cools it. The cooled coolant returns to the engine, and the process repeats.
Why Is My Truck Overheating?
If your truck is overheating, then it may be suffering from one of these reasons:
Insufficient coolant levels
Low coolant levels can lead to inadequate heat dissipation, causing the engine to overheat.
Cooling system leaks
Leaks in the radiator, hoses, or water pump can result in coolant loss, reducing the system's ability to cool the engine.
Malfunctioning thermostat
A faulty thermostat may not open and close properly, disrupting the coolant flow and leading to overheating.
Clogged radiator
Accumulated debris, rust, or mineral deposits can obstruct the radiator's cooling fins, impeding proper heat transfer.
Broken water pump
The water pump is responsible for circulating the coolant. If it fails, the coolant won't flow efficiently, resulting in overheating.
If you're suffering from any of these issues, then just pay us a visit at C. M. T. S., Charlton, MA, and our team will get you patched up and back on the road in no time.
Signs of Heavy-Duty Coolant System Failure
Recognizing the signs of coolant system failure is crucial to preventing major engine damage. Keep an eye out for the following indicators:
- Temperature gauge consistently shows higher-than-normal readings
- Steam or smoke from the engine
- Sweet or pungent odor inside or outside of the truck
- Coolant puddles under the truck
- Engine misfires or performance issues
- Coolant discoloration or contamination
(If the coolant appears rusty, oily, or contains debris)
- Coolant reservoir level changes
- Unusual noise
(Gurgling, hissing, or grinding sounds coming from the engine)
- Engine warning light illuminating
- Engine overheating
(Temperature gauge reaches the red zone)
If you recognize any of these signs in your heavy-duty truck, then it requires immediate attention from our mechanics at C. M. T. S., Charlton, MA. Failure to address these now can cause more expensive repairs down the road.
