Antifreeze

Engine coolant is an important liquid for your car in order to keep it running. The product is found in your car radiator and is usually refilled by pouring it into distinct tanks connected to the radiator. This is necessary because pouring it into directly into the radiator it can be dangerous. This liquid runs in a circular pattern under the hood to maintain the temperature for the most important components, particularly the engine of the car. Without it, the car would not be able to function anymore and moreover, the engine might overheat and destroy. Water is not enough to keep the system cool because the high temperatures inside the system will immediately boil it off so this is why it represents an important feature for the well being of your vehicle.

Rules You Should Always Follow

If you want to protect your engine and ensure the longevity of it, it’s very important to follow certain rules. You may want to purchase an engine coolant in order to manage the temperature and heat that comes out of the radiator. You do not have to necessarily spend a lot of money to get a product of good quality as they all have been designed to do one exact thing which is to keep control. Nonetheless, this does not mean that the newer engines need the same mixture that the older versions do. Pay close attention to the 3 following rules and you will keep the engine as efficient for as long as you can:

  • Avoid mixing – If you have run out of engine coolant, you should never mix it with another type. As we have already highlighted, in the olden days, there was a standard coolant made specifically for older engines to stop corrosion and excessive wear-out. It was typically a light green and made of special mixtures. The new ones have developed and became more innovative. By mixing the two together you will notice that it will not have the same cooling effect. In fact, you can risk turning the mixture into a gel that will clog up the engine.
  • Ratio is important – When you look at the bottle you want to purchase, you want to pay close attention if it’s already prefixed with a 50/50 ratio. If it is, you can use it without the need of adding anything extra. Whereas, if it isn’t, you should make sure that you add enough water to make the same exact ratio. If you do not take into consideration our advice you will make a mixture that is too weak to function properly. In the situation where the liquid is too strong, you will risk clogging the engine again.
  • Water – Adding water when your car is running low on engine coolant shouldn’t be damaging to the engine or create more problems. This isn’t a long-term solution so you need to start looking to purchase an engine coolant. You should never add anything else.

Frequently Asked Questions


?What is the difference between coolant and antifreeze?
Antifreeze is a concentrated product made of glycol and other inhibitors. It has to be diluted in order to be used. The outcome is usually the coolant.

?What type of antifreeze does my car need?
This will be indicated in the vehicle handbook, if is not specified ask your dealership.
?What does propylene glycol represent?
This substance is offered by a number of suppliers less toxic than the ethylene glycol ones. They have a similar performance to ethylene products but with a lessen degree of toxicity.

In the end, let’s not forget how important is to use the right antifreeze at the right concentration. Modern car cooling systems are smaller and the operating temperatures are higher, thing which makes it more important to use it correctly. You can choose the correct type of antifreeze by reading the vehicle’s handbook where you can find all the needed information. If there is no handbook you should check a dealer.
