The Essential Facts About the Antifreeze Coolant

The primary objective of antifreeze coolant is to take away the heat in your engine. This is the reason why this is one of the neglected fluids. This is made up of a 50% mixture with 50% mineral free water.

What Does the Antifreeze Coolant Do?

  • Lessening the freezing point of the cooling system.
  • Increases the warmth and the system thus simmers.
  • Whereas, it increases the temperature and consequently the system will simmer.
  • It acts as the water pump’s lubricant. Because of its various chemicals the pH levels is sustained. This will save the different materials from rust.

What is important about the antifreeze coolant is without it the heat generated by the persistent internal burning will damage the engine rapidly. Therefore, water in itself is not enough to keep the entire system cool. Finally, the water inside the system will soon vaporize. Similarly, in extreme cold weather, the water will surely be frozen when the car is not being used.

Acidic Antifreeze Coolant

After a certain period of time, the antifreeze coolant will turn to be acidic; thus, losing its rust preventing qualities that results to rust. This can destroy the following:

  • Water pump
  • Thermostat
  • Radiator
  • Radiator Cap
  • Hoses and Fittings

Indications that Tells You to Change Your Antifreeze Coolant:

  • Temperature Gauge Greater or Decreased than the Standard

    • When the cooling system is working well, the narrow pointer will indicate that it is in the “normal” state. However, if the needle pointer goes up or down, it shows you that there is an error in the cooling system of your car. It could be either the cooling fan or something that obstruct the radiator.
  • Coolant Light Appears

    • If while you are driving coolant light suddenly appears, then it is an indication that your engine is too hot. This could be due a leak that happened because of a cracked or damaged hose.
  • Heater Does Not Work

    • Your car heater clears off of a similar coolant in the engine. Should the engine is dripping coolant or if there is an obstruction, the heater will not function well.
  • Coolant Drip

    • If you see a pink, green, or orange muddle in your garage then your antifreeze is dripping. Clean it well as it is harmful to both humans and pets. Now, if there is a loss but no dripping is seen, this is caused by the internal engine gasket failure.
  • Weak Gas Mileage

    • Should the temperature of the engine goes down more than the usual range, the fuel will not evaporate correctly, which will harm your fuel economy.
  • Sweet but Toxic Smell

    • Ethylene glycol is dripping in some place. It could be the heater hose if not the radiator, the cylinder head or a bad intake manifold gasket. It could probably be from a dripping radiator cap. You will know it the minute you smell something outside your car. However, do not let the sweet smell deceive you because this is extremely toxic!
