What is a coolant flush and how does it work?

Engine coolant, sometimes referred to as “antifreeze”, is a fluid that serves to control the operating temperature of your engine. It does its job by flowing through passages inside the engine where it absorbs heat caused by combustion. The hot coolant is forced out of the engine by the water pump, through a rubber hose, and into tiny tubes inside the radiator. Air blowing through the radiator steals heat from the coolant before the liquid makes its way back to the engine to pick up more heat. A coolant flush is a service aimed at removing all of the old coolant in the system, flushing out any leftover residue, and replacing it with new coolant.

Signs that your coolant needs to be replaced

The first sign that your engine coolant needs to be replaced is the recommendation of the manufacturer in the maintenance schedule for your vehicle. The coolant should be changed periodically according to the schedule to prevent problems with engine performance. But there are other signals to let you know there is a problem with the cooling system that could require either a coolant change or coolant flush. These include

Your engine is overheating

The coolant level drops due to fluid loss

You notice a sweet syrup smell inside or outside the vehicle

The vents produce no heat when the heater is turned on

How is this service performed

How is a Coolant Flush done?

There are two services related to replacing the coolant in an engine

  • draining and filling the system or a coolant flush. Flushing the coolant system is a bit more involved and serves to remove residue that is left behind when the coolant is merely drained and refilled. To perform a coolant flush, a technician will either connect a dedicated coolant flush machine or allow the engine’s water pump to do the work. With either procedure, the old coolant is drained from the radiator. Clean water is forced through the cooling system, often with a special cleaning agent added (this might be done using a flush machine or by running the engine for a period of time). Once the system has been flushed, the water is drained. Although not required, a vacuum device might be installed (included on a flush machine) to remove air from the system before installing fresh coolant.
