What is the cooling system flush?
Your cooling system is what prevents your car from overheating. It operates by circulating a mixture of water and coolant through the engine. Over time the coolant mixture becomes contaminated with scale and rust, which can clog and damage the cooling system parts. A cooling system flush basically flushes out the entire system of contaminants and replaces the coolant mixture with fresh coolant and water.

Bear in mind:
Your mechanic will drain the fluid, clean the system with coolant cleaner, and use water to take out the remaining coolant. After cleaning the system, the mechanic will fill it up with new coolant. This process is active and an approved industry method of flushing your vehicle’s cooling system.
How to Fix:
Fix flush chemical to radiator
Bring the car to working temperature
Drain the old coolant
Close valve and refill with water
Repeat the process
Fill radiator with a 50/50 mixture of coolant and water
Check for leaks and fan operation
Some vehicles are furnished with a low coolant sensing system. Should this light come on, have your vehicle checked for leaks or other possible causes for the low coolant level.
Keep an eye on the service upkeep schedule provided by the manufacturer to get the coolant changed at regular intervals. In general, it is a good practice to change the coolant every 40,000-50,000 miles.
