How Can You Change Your Coolant?

Changing a coolant is very important for a vehicle. It ensures its longer life and better performance. So, here’s a step by step guide to your coolant/antifreeze change yourself without spending a ton of money at garages or repair shops. If your car is an older model, then before changing the coolant, set your temperature control on the max.

If your model is a newer one, then it must be an electric control. So, you should probably turn the ignition ‘ON’ or run the car for a few minutes. This will open up all the coolant pores and while you are draining the coolant, it will ensure that all of the coolant is drained properly.

Word of Caution: Before working on your car in any way make sure the engine and the radiator have cooled down completely.

Step One: Drain the existing coolant.

First you need to drain the old coolant from three important places, radiator, engine and the coolant reservoir.

  • Before you being to drain coolant, remove the radiator plug. You might want to rest the cap on top to avoid any kind of contaminants falling into the radiator.
  • To actually start draining the coolant, put any kind of pot or container under the radiator and loosen the drain plug. This will flush out all the coolant that’s there in the radiator.
  • After all of the coolant is drained, it’s time to flush out the engine of any coolant. Put your container under the engine. Remove the engine drain plug to flush out the engine and the heater core of any coolant.
  • Now, put the engine drain plug back and tighten it. Do the same with the radiator drain plug. It will be good idea at this point, to use a good sealant before tightening these plugs to avoid any kind of leakage.
  • Now come to the Coolant Reservoir. Drain it of any and all coolant in it. Clean it up properly and put it back.

Step Two: Put Fresh and New Coolant in the Car.

For this, you need to refer to your user manual for deciding on what kind of coolant mixture is suitable for your model.

Now take the concentrated coolant and mix it with the prescribed ratio of distilled water in a bucket or any container. It’s imperative that you use distilled water for this purpose as tap water can contain some contaminants.

  • Now that you have made the coolant mix, put it in your reservoir. You’ll notice that you reservoir would have marks on it. Do not exceed the ‘Max’ line.
  • Now put the required amount of coolant in the radiator. The amount will be different for different car types. Make sure the coolant is below the neck or the base of the radiator.
  • Now run the engine for a few minutes. This will remove any air particles from the engine and the radiator. Once the engine have warmed up, the coolant level in the radiator will go down. This will happen because of the Thermostat opening up.
  • Now is a good time to add more coolant.
  • Once this is complete, tighten the radiator cap.
  • Now finally, run the engine one final time to check for any possible leaks in the car.

Caution: After the refilling the coolant is done, clean the area thoroughly of any coolant that might have spilled during the process. This part is especially important if you have any animals or pets roaming around. Even if you have little kids at home that might wander about to this place of repair, this is important. The sweet smelling coolant smells delicious and appetizing to animals who might consume it. This coolant liquid is lethal to animals and even small children as well, which is why it is imperative that you clean the place thoroughly.

Some Coolant Myths Busted

Let’s discuss about some coolant Myths and burst those bubbles of misinformation.

One- Either Water or Coolant.

The cooling system of a car needs a mix of coolant and water for smooth functioning. Usually this ratio is 1:1. If you skip any of them, the cooling system would not work properly.

If you skip coolant and only add water, it will lead to the corrosion of engine and other parts of the car. You need both of these to replace engine coolant for smooth functioning of your car.

Two- No Servicing for the Cooling System.

The entirety of your car needs regular servicing for better performance and longer service life. Regular check-ups are also necessary to know if you need to replace a certain part.

Three- Changing Coolant is a Waste of Your Time and Money.

Your coolant will aid water in maintaining a proper temperature of your car. This doesn’t mean that you can use the same coolant for a long time without refilling the engine coolant.

If a coolant gets old, it gets contaminated. A contaminated coolant won’t cool the engine properly which will lead to engine overheating. Also, if the coolant gets older, it will start corrosion of metal car parts. So, it is extremely important that you change the coolant regularly.

Four- Leaks Don’t Need To Be Addressed And They Don’t Matter.

Usually people say that small leaks do not matter a lot and they don’t need to be addressed.

Small leaks actually can lead to major problems in the engine. So, you need to regularly check for any leaks in the car and repair it as soon as possible.
