2018 Subaru Legacy Coolant

Coolant, as it relates to vehicles, is normally a liquid or gas substance used to regulate the temperature of your engine. Liquid coolants are ordinarily half water and half ethylene glycol. Water is used to transfer heat while ethylene glycol is used to lower the freezing point of the liquid. In colder climates, this is exceptionally vital. This probably isn't the first time you've heard of ethylene glycol as it is the prime ingredient in the popular term "antifreeze". Keep in mind, you never want to pour antifreeze or water by themselves into your engine system. They need to be mixed to design the proper coolant.

You can purchase ready-made mixtures of coolant that already have water added, or you can purchase full-strength antifreeze which needs to be diluted with distilled water before being added to the engine system.
