The cooling system in a vehicle is one of the most vital components to maintain engine health. Filling radiator coolant correctly is an important step in maintaining optimal operating temperatures and preventing overheating problems. In this TransTRACK article, we will detail the steps you need to follow how to fill radiator coolant properly. From basic understanding to practical techniques, let’s explore how to do this task properly and efficiently!

How to fill radiator coolant in a car

Filling a car’s radiator water is a relatively simple task, but it needs to be done properly to ensure optimal engine performance and prevent overheating problems. Here are the steps to fill the car radiator water correctly:

1. Make sure the engine is cold

Filling radiator water can only be done when the engine is cold. This is very important because when the engine is hot, the cooling system will have high pressure and hot fluids that could harm you if they come into contact with them.

2. Check the Coolant Level

First, locate the coolant reservoir tank. It usually comes in the form of a transparent tube with “minimum” and “maximum” markings. When the engine is cold, see where the fluid level is. The liquid must be between the minimum and maximum marks. If it’s too low, this could indicate a leak or evaporation that needs to be addressed.

3. Use a Funnel

A funnel is used to add liquid more easily and avoid spills. Make sure the mouthpiece is clean and free of debris before use.

4. Fill the Radiator

When all the tools and materials are ready, place the funnel over the coolant filling hole in the reservoir tank. Carefully pour the water and coolant mixture into the funnel. It is important to use the correct mix, which is usually 50% water and 50% coolant. This mixture helps maintain engine operating temperatures within a safe range, prevents freezing at low temperatures, and prevents overheating at high temperatures.

5. Close the Meeting Again

After the liquid has been poured into the reservoir tank, be sure to seal it back tightly. This is important because a tightly closed lid helps maintain the necessary pressure in the cooling system.

6. Check Back

After you have completed the filling steps, do a final inspection. Check that there are no spills or leaks around the reservoir tank or radiator cap. Also make sure that all lids are tightly closed.

Filling radiator water properly is very important to maintain engine performance and prevent problems related to overheating. If you’re unsure or have never done this before, it’s best to ask a professional mechanic for help or refer to your car’s owner’s manual. Never neglect this task, as a good cooling system is essential for the longevity and health of your car’s engine.

How to fill radiator coolant in a truck

The steps for filling radiator water on a truck are actually similar to filling a normal car radiator water. However, trucks generally have larger and more complex cooling systems. The following is a more in-depth explanation of how to fill the correct truck radiator water:

1. Make sure the engine is cold

As with a car, make sure the truck engine is cold before opening the cooling system. This is to avoid the risk of exposure to hot liquids or steam.

2. Identification of Coolant Tank Locations

Locate the coolant expansion tank on your truck. These tanks are usually located near the engine and are marked “minimum” and “maximum”. On trucks, these tanks can be larger and more complex than a normal car.

3. Check the Liquid Level

Check the coolant level in the expansion tank. The liquid level should be between the minimum and maximum marks. If it is too low, there may be a problem such as a leak or expansion of the coolant as the temperature increases.

4. Preparation of Tools and Materials

Prepare a mixture of water and coolant in the recommended ratio (usually 50:50) and a suitable funnel.

5. Use a Funnel

Use a funnel to more easily introduce the coolant mixture into the expansion tank. Make sure the mouthpiece is clean and free of debris before use.

6. Fill the Radiator

Place the funnel in the expansion tank fill hole. Carefully pour the water and coolant mixture into the funnel until it reaches the desired level.

7. Close the Meeting Again

After you have finished filling the liquid, be sure to close the expansion tank cap tightly. This helps maintain the necessary pressure in the truck’s cooling system.

8. Check for Leaks

Perform a final check to ensure that there are no coolant spills or leaks around the expansion tank or other parts of the cooling system.

9. Run the Machine and Check Again

Once all steps are completed, start your truck engine and let it run for a few minutes. This will help circulate the coolant throughout the system. After some time, check the coolant level again and make sure it stays between the minimum and maximum marks.

It is important to always refer to your truck’s owner’s manual as each truck model can have differences in their cooling systems. If you are unsure or have no experience, it is better to consult a professional mechanic who is familiar with trucks.
