How Much Antifreeze Does My Car Need?

Antifreeze coolant safeguards your engine against extreme temperatures. It's crucial for maintaining the perfect balance within your vehicle's cooling system, preventing freezing in the winter and overheating in the summer. 

Knowing the correct amount is essential for your car's performance and longevity. But how much antifreeze does my car need? This is one of the most common questions vehicle owners ask themselves, and we’re here to help you find clarity.

Your car’s antifreeze needs depend on several factors, including your vehicle's make and model, the climate you're driving in, and the specific requirements outlined in your owner's manual. 

From understanding its purpose to mastering the art of maintenance, we’ll cover everything you need to know about antifreeze below. Plus, we'll guide you to where you can find the best antifreeze coolant in the UK - right here at Jennychem.

What is the Purpose of Antifreeze?

Antifreeze serves as a critical fluid in your car's engine, performing dual protective functions that are essential throughout the year. In winter months, it prevents the engine's cooling system from freezing, a condition that can cause catastrophic engine block cracks and expensive repairs. 

Conversely, during the hot summer months, antifreeze works to elevate the boiling point of the cooling system, preventing the engine from overheating even under intense operating conditions.

The importance of antifreeze, however, extends beyond temperature regulation. It also plays a vital role in inhibiting rust and corrosion within the engine's internal passages. 

The chemical composition of antifreeze includes additives that form a protective layer on metal surfaces, which helps to preserve the integrity of the engine and cooling system components over time.

Moreover, antifreeze helps to maintain efficient heat transfer. It's formulated to carry heat away from the engine to the radiator where it can be dissipated, thereby ensuring that your vehicle runs at an optimal temperature. This heat regulation is crucial for maintaining performance and fuel efficiency.

How Much Antifreeze Does My Car Need?

You can see why antifreeze is such an essential fluid for your vehicle - but how much antifreeze does a car take? 

As we said earlier, there is no one size fits all answer. Let’s take a look at the steps to determining your cooling system’s capacity along with the signs of low antifreeze to watch out for.

Determining the Capacity of Your Cooling System

The quantity of antifreeze your car requires hinges on the capacity of its cooling system, which varies based on the make, model, and engine size. 

Typically, a standard passenger vehicle may need between 5 to 12 liters of antifreeze, but it's imperative to consult your vehicle's owner's manual for the precise specifications. The manual will provide you with the exact capacity of your cooling system and the recommended antifreeze type.

Signs of Low Antifreeze Levels to Watch Out For

Monitoring your antifreeze level is a critical part of routine vehicle maintenance. A drop in the coolant level can indicate a leak in the cooling system, which could lead to engine overheating and potential damage. Here are some things to watch out for:

  • Overheating Engine: If your dashboard temperature gauge is consistently higher than usual, or if you notice steam coming from under the hood, your engine may be overheating due to low antifreeze.
  • Heater Not Working: When the antifreeze level is too low, it may not reach the heater core, resulting in no warm air blowing from your car's heater.
  • Coolant Light on Dashboard: Many modern vehicles have a coolant warning light that indicates when the antifreeze level is low.
  • Visible Leaks: Puddles of coolant under your car or a sweet-smelling, brightly coloured liquid (usually green, orange, or pink) leaking from the engine area are telltale signs.
  • Poor Fuel Economy: A low antifreeze level can cause your engine to run hotter and less efficiently, leading to worse fuel economy.
  • Unusual Noises: If you hear gurgling or boiling sounds from the engine area, it could be air in the cooling system or boiling coolant due to low antifreeze levels.

If you notice any of these signs, it's crucial to address the issue immediately. Low antifreeze can lead to serious consequences down the road. 

Tips on Choosing the Right Antifreeze and Filling Your Reservor

From picking the right antifreeze to diluting the concentrate, safely disposing of old antifreeze, and more - we’ll cover everything you need to know to confidently manage your antifreeze levels below!

Selecting the Appropriate Antifreeze for Your Vehicle

Selecting the appropriate antifreeze for your vehicle is a critical step in maintaining your car's health and performance. The right antifreeze type will ensure compatibility with your engine's materials and provide adequate protection against freezing, overheating, and corrosion.

So, what antifreeze does my car need?  Here’s what you should consider when choosing a formulation: 

  • Refer to Your Owner's Manual: This is your primary source of information for the recommended type of antifreeze for your specific vehicle.
  • Understand Antifreeze Types: There are several types of antifreeze, including Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Each type has different properties and service intervals.
  • Check for Compatibility: Ensure the antifreeze is compatible with your car's engine materials, such as aluminum or cast iron, and the type of antifreeze already in your system if you're topping up.
  • Consider the Climate: In extremely cold environments, antifreeze with a lower freezing point may be necessary.

The Process of Checking and Filling Antifreeze

Once you've selected the right antifreeze, checking and filling your reservoir is a straightforward process. Where does antifreeze go, though? 

The coolant reservoir is typically a translucent plastic container near the radiator with minimum and maximum level markings. Be sure to differentiate between your coolant and your windscreen wash reservoirs.

Ensure the engine is cool before you remove the cap. The coolant level should be between the minimum and maximum marks. If you’re running low, add the correct antifreeze and water mixture until it reaches the correct level.

After filling, monitor the level over time to ensure there are no leaks in the system. 

Flushing Antifreeze Coolant Safely

Flushing your antifreeze coolant is also an important part of maintenance. It should be done every 30,000 miles or so, but again - consider your specific driving conditions and the make/model of your vehicle. When the time comes, though, here’s what you need to know:

  • Drain the Old Coolant: Locate the drain plug on the bottom of the radiator and drain the old coolant into a container. Be sure to safely dispose of antifreeze, as it's toxic and harmful to the environment. 
  • Flush the System: Use distilled water to flush out any remaining old coolant and contaminants. Run the engine with the water and heater on until it reaches operating temperature, then drain the water.
  • Fill with New Antifreeze: Once the system is drained and flushed, fill it with the new antifreeze mixture, ensuring no air pockets are trapped in the system.

There you have it! Everything you need to know about monitoring your car’s antifreeze levels and keeping them topped off. At this point, the only thing left to do is pick up a container of the UK’s leading antifreeze formulations - right here at Jennychem.
