Due to the engine‘s action, the cars generate a large amount of heat, and the cooling system is tasked with dissipating this heat from the engine. This is done by a vehicle fluid called coolant or antifreeze, and aided by cooling system components such as the radiator, water pump, thermostat, heater core, and hoses.
With continuous use over the years, the coolant becomes degraded and contaminated, losing its heat-transferring capacity. That’s why the vehicle undergoes a coolant flush. The coolant flush, also known as a radiator flush, is the process of thoroughly removing old coolant along with accumulated contaminants from the system and refilling it with new coolant.
Cooling System Flush Procedure
- Initial Drain: The old, degraded, and contaminated coolant is drained from its reservoir and radiator. During this phase, approximately 60-70% of the contaminated fluid is removed, and the remaining portion remains in the form of sludge and deposits, along with coolant in the engine block and heater core.
- Draining With Cleaning Solution: A specialized cleaning solution, also known as a flush chemical, is introduced in the cooling system along with distilled water. This helps in thinning and removing the degraded coolant and sludge that have become stuck to the engine block, heater core, and hoses, along with system rust and scale. Using a specialized flushing tool and running the engine for a limited period, the flush chemical is circulated throughout the system thoroughly, so that all the contaminants are replaced. Then the flushing chemical is thoroughly drained.
- Water Treatment: After draining the flush chemical, the cooling system is treated with water, preferably distilled water, to rinse the system of any residues. This process is repeated multiple times, and the cooling system is thoroughly rinsed till all the contaminants and old coolants are removed from the system.
- Coolant Refilling: After the water is drained and the cooling system is dried, it is refilled with new coolant. At Huron Automotive, we use high-quality brand-approved coolant that is compatible with the vehicle’s specification and performs at its peak.
A cooling system flush helps your car from multiple fronts. Proper heat transfer enables the engine to perform efficiently, produce more power, and remain healthy. It also removes system contaminants and sludge that accelerate component wear and corrosion. Prevention of overheating prevents severe engine damage. It also extends the lifespan of cooling system components and helps improve heater performance.
However, it is crucial to understand when, as an owner, you should perform a coolant flush in your vehicle. As the old coolant degrades and reaches the point where a flush is necessary, the vehicle exhibits several warning signs that indicate the need for this service. These are frequent spikes in the temperature gauge. The coolant in the reservoir is brown, rusty, or has a sludgy, oily texture, with visible flakes and debris in the coolant, and poor cabin heater performance.
Delayed Cooling System Flush Consequences
Cooling System Component Failure
The components of the cooling system through which the coolant passes malfunction when the coolant is contaminated and filled with debris. For example:
- The abrasive material destroys the internal motor of the water pump.
- Clogged passages create leaks in the radiator.
- Debris can cause the thermostat to malfunction, resulting in perpetual overcooling or overheating.
- The heater core gets clogged when the coolant is contaminated, resulting in expensive repairs.
Severe Engine Malfunction
A degraded coolant fails to dissipate heat from the engine, causing engine overheating. Overheating in the engine can cause failure in various components, including the head gasket, pistons, and valve components. It also burns the engine oil, preventing the engine from receiving proper lubrication. This causes friction to increase and, in turn, leads to friction-induced accelerated corrosion. If ignored, this could lead to catastrophic engine failure, necessitating engine rebuilding or replacement.
