Placement of the car

The coolant replacement requires your car should be placed at a height, and this is for a reason. The cap for extracting the coolant out from the radiator is usually placed below the radiator in most of the cars, and for that, you need to lift the car a bit up, preferably on a lift. You can also lift the car a bit up through a car jack which comes standard with all the cars nowadays, by parking the car on a flat and firm surface.

Emptying the radiator

The radiator of your car generally has two caps  one at the top and the other at the bottom. For emptying the old coolant, you need to place an empty vessel just below the bottom cap of the radiator. After that, unscrew the bottom cap, which will allow the already present old coolant to flush out of the radiator. After the coolant gets flushed out completely from the radiator, screw the bottom cap back to its original position.

Filling up the new coolant

After confirming that the bottom cap of the radiator is tightened back, bring back the car to its original placement by removing the jack. After that, unscrew the upper cap and slowly fill the new fresh coolant with the help of a funnel. Ensure that there is no leakage thereafter at the bottom. Do keep in mind to not fill the coolant up to the uppermost mark, for it can result in unwanted spillage of the coolant out in the engine bay.
