2021 Toyota Highlander 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 typically 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 immensely important. This undoubtedly isn't the first time you've heard of ethylene glycol as it is the main 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 create 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. Give the experts at Nalley Toyota Stonecrest a call at 7706290279 or schedule service online and let one of our mechanics and service specialists handle your coolant flush.

Every vehicle manufacturer, including Toyota has developed its own coolant or requires a specific coolant that is distinct to individual years and models. There are many colors of coolants to help distinguish each including purple red, yellow, green, blue, and orange. It is important to do your research if you plan to buy, flush, or replace the coolant in your vehicle. Many models will not be compatible even with "universal" coolants or antifreeze.

How long does 2021 Toyota Highlander coolant last?

How often you need to flush and replenish your vehicle's coolant relies on the type of coolant. There are many types of coolants. Up until the mid-1990s there was essentially only a single type of coolant. It was a green formula coolant that contained corrosion inhibitors that only lasted between 24,000 - 36,000 miles or between two to three years. This type of coolant is not suggested for newer vehicles which come equipped with a longer-lasting coolant.

Newer coolants use an Organic Acid Technology (OAT) and last up to twice as long as older coolant. In some cases these long-life coolants can last over 5 years or 100,000 miles.

For specific advice on what intervals your coolant needs to be changed, check your 2021 Toyota Highlander maintenance schedule within your owner's manual or give Nalley Toyota Stonecrest a call at 7706290279 today and ask one of our OEM-trained mechanics or advisers.
