Engine coolant, also referred to as antifreeze, is a substance used to transmit and expel extra heat produced by combustion. Although there are many other kinds of engine coolants, the majority of those that are commercially accessible are 50% propylene glycol or ethylene and 50% water. To determine the proper engine coolant for your car, see your owner’s handbook. 

During an engine coolant cleanse, the existing coolant is removed, and the chemical buildup is also eliminated (such as rust, sludge, and dirt). The cooling system is then refilled with fresh coolant, which improves cooling system performance by better regulating engine temperature. 

The Advantages Of Coolant Flushing 

Scale, rust, and other deposits that accumulate in the coolant system over time are removed via coolant flushes. Since these deposits can damage your engine and/or the entire cooling system by causing the engine to overheat, they must be removed. Additionally, modern coolants have lubricating chemicals that help the water pump last longer by lubricating it. An engine flush makes that the antifreeze’s lubricant is in good operating order. 

As the coolant ages, the chemicals that shield the engine from rust degrade. Rust and impurities thus accumulate in the water pump and engine, degrading energy. An antifreeze flush stops these problems in their tracks. 

A coolant flush also enables the maintenance staff to examine other components and systems. These consist of the full cooling system, including the belts, coolant hoses, thermostats, radiators, and belts. These inspections aid in finding problems like leaks and other concerns. 

Acidification of aging coolant can lead to problems. Acidic coolants have the ability to corrode and destroy rubber hoses, water pump bearings, and even metal parts in the engine block.

The Need for Regular Engine Coolant Changes 

While our service staff will be able to tell you whether or not you need an engine flush, you should evaluate your car’s status, functionality, and performance to see if a coolant flush is necessary. You are in a better position to identify problems with your car because you are the one who knows it the best. 

Watch for these indicators to determine when to arrange an engine coolant change: 

Aging vehicle- It’s time for a coolant flush if you haven’t performed one in a while or if you’ve driven your car for five years without one. 

Heating up- Engine overheating is a sign that the cooling system, coolant, or both are not working properly. To get the heat balance back, you need to flush the coolant. 

Temperature- related engine check lights The engine may be in trouble if your car’s internal thermometer, heat indicator, and check engine light frequently illuminate. Pressure will be reduced by a coolant flush. 

As you may expect, each car model and make has a varied maintenance plan. You can find instructions on how often to perform a coolant flush in your owner’s manual (typically, once a year).
