How to Put Antifreeze in Car Radiator

Understanding how to maintain your vehicle is crucial for any car owner – whether you’re a new driver or a seasoned road warrior. One of the most basic yet important tasks is handling the cooling system, which includes topping up and changing the antifreeze in your car’s radiator.

How to Put Antifreeze in Car Radiator

Antifreeze, also known as coolant, serves a key role in keeping your engine running at the right temperature, especially in extreme weather conditions. In this guide, we’ll walk you through how to put antifreeze in car radiator.

The Importance of Regular Antifreeze Maintenance

Ensuring your car’s radiator contains the correct amount and type of antifreeze is vital for preventing your engine from overheating and freezing. Antifreeze not only lowers the freezing point of the water in your radiator but also raises its boiling point, protecting the engine from extreme temperatures.

Moreover, antifreeze contains corrosion inhibitors that help protect the radiator and the entire cooling system from rust and corrosion, which could result in leaks and costly repairs. Neglecting to check and replace antifreeze can lead to major engine failures, such as blown gaskets, cracked cylinders, and irreparable damage. However, with regular maintenance, you can avoid these issues and keep your car running smoothly.

Understanding Antifreeze

Before you dive into adding antifreeze to your car radiator, it’s essential to understand the basics.

What Is Antifreeze?

Antifreeze, or engine coolant, is a colored fluid typically green, red, yellow, or blue, mixed with water and poured into a car’s radiator. It is composed of a base chemical, which can be ethylene glycol or propylene glycol, and other additives that offer several benefits to the car’s cooling system.

Types of Antifreeze

There are two primary types of antifreeze:

  • Ethylene Glycol: The most common and less environmentally friendly option, also known for its sweet smell and taste.
  • Propylene Glycol: A safer, less toxic alternative that’s typically used in newer vehicles or as an alternative to ethylene glycol due to its biodegradability.

Differences in Antifreeze Formulas

In addition to the glycol type, antifreeze comes in different formulas:

  • Inorganic Additive Technology (IAT): The traditional green formula that requires more frequent changing, typically every two years or 30,000 miles.
  • Organic Additive Technology (OAT): A long-life formula (often orange in color) that can go 150,000 miles before needing replacement.
  • Hybrid Organic Acid Technology (HOAT): A midrange formula (often yellow) that lasts longer than IAT but not as long as OAT, typically needing replacement every 5 years or 60,000 miles.

Checking your vehicle’s owner’s manual or consulting a professional will guide you on the right type of antifreeze to use.

  • Double-check that you are using the correct type of antifreeze according to your vehicle’s requirements.

10 Steps to Safely Put Antifreeze in Your Car Radiator

As the temperatures drop, it’s essential to ensure your vehicle’s radiator is ready to handle the chill. Proper antifreeze levels protect your engine from freezing while also providing critical cooling properties. Here are ten simple steps you can follow to safely and effectively add antifreeze to your car’s radiator.

1. Prepare the Materials

Begin by gathering the necessary materials and tools: your chosen antifreeze, a funnel, safety goggles, a mixing container, and a cloth to wipe up any spills. It is important to choose the correct type and amount of antifreeze for your specific vehicle. Refer to your owner’s manual or consult with a mechanic if you are unsure.

2. Park the Car

Ensure your vehicle is parked on a level surface. If your engine is hot, let it cool to avoid burns and prevent pressure from building in the cooling system.

Make sure the parking brake is engaged and put your vehicle in park or first gear for manual transmission. If you have an automatic, make sure it’s in park. This will prevent your car from rolling while you are working on it.

3. Locate the Radiator Cap

The radiator cap is typically located on top of the engine. It’s important not to remove the cap while the engine is hot or warm to prevent scalding. Although it may seem like a simple task, locating the radiator cap can sometimes be tricky.

To begin, open your vehicle’s hood and secure it with the prop rod. Next, locate the coolant reservoir which is often a white or transparent plastic tank. The coolant reservoir is connected to the radiator by a hose that leads to the cap.

4. Open the Radiator Cap Slowly

Once the engine has cooled, slowly turn the cap counterclockwise but keep it downward to release any residual pressure. If you hear a hiss, wait for it to subside before fully removing the cap. This will prevent any hot coolant from spraying out and potentially causing harm.

After the pressure has been released, remove the cap completely and set it aside. Inspect the cap for any cracks or damage before placing it back on. If there are any concerns, replace the cap with a new one.

5. Pour Antifreeze Carefully

Use the Funnel to Prevent Spills

Use the funnel to prevent spills and slowly pour the correct antifreeze-to-water ratio mixture into the radiator. Your vehicle’s manual should specify the right ratios for your engine.

Be sure to use the correct type of antifreeze for your car as well. There are different types such as ethylene glycol and propylene glycol, so consult your owner’s manual or a mechanic if you’re unsure.

6. Fill to the Brim

Continue to fill the radiator until the antifreeze is almost spilling out. This helps remove any air from the system. You can also check the level of antifreeze in the radiator by using a dipstick or by looking at the markings on the side of the plastic overflow reservoir. Make sure to read your vehicle’s manual for specific instructions on how to properly check and fill the radiator.

7. Check Hoses for Leaks

While the cap is off, look for any leaks or cracks along the hoses connected to the radiator. These should be inspected regularly for any signs of wear. If you notice any leaks, it is important to have them repaired immediately to prevent further damage to your vehicle.

8. Top off the Reservoir

If your vehicle has an overflow reservoir, check it as well and add antifreeze if needed to the “full” line. Don’t wait until your vehicle overheats to check the reservoir. Regularly topping off the reservoir will ensure that your engine is always supplied with enough coolant, preventing it from overheating.

8. Replace Radiator Cap

Once the antifreeze is added, put the radiator cap back on securely by pressing it down and turning it clockwise until it clicks. This ensures that there is no leakage and the antifreeze remains in the radiator.
