Commercial Truck Coolant System Repair Services in Edmonton, AB

Fleetgo Heavy Duty provides expert coolant system repair in Edmonton, AB for heavy-duty trucks, diesel engines, and commercial fleets. An overheating engine is one of the most common causes of roadside breakdowns, so we diagnose and repair the entire cooling system, from the radiator, water pump, thermostat, and hoses to the coolant filter and EGR cooler.

The Basics of Coolant Systems

Radiator

The radiator is the most visible component of the coolant system and is responsible for removing heat from the engine coolant. As the hot coolant flows through the radiator, it passes through a series of small tubes surrounded by thin metal fins. As air passes through the fins, it dissipates the heat from the coolant, lowering its temperature before it is circulated back into the engine. Damage to the radiator or coolant leaks can reduce cooling efficiency, increasing the risk of engine overheating and requiring coolant system repair. A worn radiator cap or a cracked coolant reservoir can also cause pressure loss and coolant leaks that reduce cooling performance. If the water pump fails, coolant circulation is reduced, which can lead to overheating and additional engine damage if repairs are delayed.

Water Pump

The water pump is another critical component of the coolant system. It circulates the coolant through the engine, radiator, and other components, ensuring that the engine temperature remains within safe limits. The water pump is usually driven by a belt connected to the engine, and it typically contains an impeller that pumps the coolant through the system. A worn impeller or a failing pump seal lowers coolant flow and can lead to cavitation, hot spots, and overheating.

Hoses

The hoses in the coolant system are responsible for transporting the coolant between the engine, radiator, and other components. Over time, these hoses can become brittle and crack, leading to leaks and a loss of coolant. This can result in engine overheating and potential damage. Inspecting hoses for wear, deterioration, and leaks helps identify coolant system problems before they lead to more extensive repairs or roadside breakdowns.

Thermostat

The thermostat is another key component of the coolant system. It regulates the flow of coolant through the engine based on the temperature of the engine. When the engine is cold, the thermostat remains closed, allowing the engine to warm up more quickly. When the engine reaches the desired operating temperature, the thermostat opens, allowing the coolant to flow through the engine and maintain a steady temperature. A faulty thermostat can prevent the engine from maintaining its proper operating temperature, making timely diagnosis and replacement an important part of coolant system repair.

Understanding the basics of the coolant system is important for maintaining the health of your heavy-duty truck. Regular inspections and maintenance of the coolant system can help to identify any potential issues before they become major problems, ensuring that your truck remains safe and reliable. Routine inspections can also identify coolant leaks, worn components, and cooling system issues before they result in costly downtime or engine damage.

Coolant, Filters & Additives for Diesel Engines

Heavy-duty diesel cooling systems depend on more than water and antifreeze. The correct coolant, coolant filters, and supplemental coolant additives (SCA/DCA) protect against corrosion, scale buildup, and cylinder liner cavitation, a common source of coolant leaks and internal engine damage in commercial diesel engines. As part of a complete cooling system service we test coolant condition, adjust additive levels, and replace coolant filters to keep the system clean and protected.

Coolant System Repair Services We Offer

At Fleetgo, we offer a range of coolant system repair services to address these common issues and keep your heavy-duty truck running smoothly. Every coolant system repair begins with an inspection of the cooling system to identify the source of leaks, overheating, or component failure so the appropriate repairs can be completed. Our services include:

1. Coolant system flush and refill - We can flush out old coolant and replace it with fresh coolant to ensure proper coolant circulation, corrosion protection, and consistent engine cooling.
2. Leak detection and repair - We can locate and repair any leaks in the coolant system, including damaged hoses, gaskets, and radiator or engine block cracks. Identifying coolant leaks early helps prevent overheating and protects critical engine components.
3. Water pump replacement - Our technicians can diagnose and replace a malfunctioning water pump to restore proper circulation of the coolant and maintain safe engine operating temperatures.
4. Thermostat replacement - A malfunctioning thermostat can result in improper engine temperature regulation. We can diagnose and replace a faulty thermostat to ensure the coolant system maintains the correct engine operating temperature and coolant flow.
5. Radiator repair and replacement - We repair or replace radiators, radiator caps, and coolant reservoirs to restore proper heat dissipation and system pressure.
6. EGR cooler and coolant filter service - We inspect and service EGR coolers and replace coolant filters to keep diesel cooling systems clean and running cool.
7. Cooling fan and fan clutch repair - A failing cooling fan or fan clutch reduces airflow through the radiator; we diagnose and repair these to prevent overheating.
