Types of Coolants

Inorganic Additive Technology (IAT):

These were the first coolants used in cars, these coolants are derived from phosphate-silicate additives. They were used to protect iron, brass, copper, and aluminum parts.

Organic Acid Technology (OAT):

The second generation of coolants are derived from organic acids combined with corrosion inhibitors. Because of their chemical makeup these coolants can last up to 5 years

Hybrid Organic Acid Technology (HOAT):

The newest generation of coolants, these are a combination of IAT and OAT coolants. The mixture of organic compounds with inorganic materials make them excellent for protecting specific types of materials.

Check the Coolant Level

Pop open the hood and take a peek inside - it's time to find out just how 'cool' your engine really is!

To check the coolant level, locate the coolant reservoir. This is usually found near the radiator and can be identified by looking for a translucent plastic container with an inscription that reads 'coolant.'

Once you have located the coolant reservoir, remove its cap and look inside. You'll want to make sure that the fluid reaches at least to the 'min' mark on the side of the container; if it doesn't, then you'll need to add more coolant.

Before doing so, however, it's important that you monitor your car's temperature gauge while driving around for a bit in order to verify that no problems exist with your vehicle's cooling system before adding any additional coolant.

The reservoir should be easy enough to find, as it normally has a coolant symbol near it. To understand the basics of a car's cooling system, look for two hoses connecting to the reservoir.

One hose will lead to the radiator and other components of the cooling system while another one is used for draining purposes.

If you can't find this container, consult your owner’s manual or take your car to an auto shop for assistance.

Check for Leaks

Inspect your vehicle for any signs of coolant leakage to make sure you're good to go!

Inspect hoses for any signs of wear or damage before adding coolant. Make sure the type of coolant you're using matches what the manufacturer recommends for your specific make and model.

There are a few things you need to look out for when checking for leaks. First, identify any wet spots around the hoses or draining systems connected to your car's cooling system. Second, check if there's an unusual amount of steam coming from under the hood when you start up the engine. Lastly, examine all visible lines and connections associated with the radiator and cooling system for cracks or signs of wear.

It's important to note that not all coolant leaks are easily visible; they can be hidden beneath other parts of your vehicle or be very small in size. If you suspect a leak but can't find it right away, consider taking your car into a professional mechanic who can help identify any potential issues so they can be addressed promptly.

Adding the Coolant or Antifreeze

Most modern vehicles use long-life antifreeze coolant, which will have a light green or yellowish hue. Once you've determined the right type of coolant, open the coolant reservoir cap and top off the fluid level until it reaches just below the maximum fill line.

Then close up your engine compartment and start up your car to ensure that everything is functioning properly.
