This is helpful in finding the right coolant to use for your car by just looking up the car manufacturer.Ĭoolants also come in different colors which can be confusing to some drivers. It is common for car manufacturers to pick one type of coolant, and then use it for all the vehicles in their line. HOAT coolant needs to be flushed out every five years or every 150,000 miles.

They do contain silicates that have corrosion inhibitors, plus additives that stop corrosion and rusting. HOAT coolants can be purchased in several different colors including orange and yellow.

HOAT coolants include silicates that help to protect aluminum, and prevent corrosion. This coolant is normally used on newer cars, and you should check with the car’s manufactures before using it to make sure it is safe and effective for your vehicle. OAT coolants need to be flushed from your car every five year or 150,000 miles.

Certain manufactures will add specific additives to OAT coolant that will stop corrosion and rust. When you have corrosion inhibitors in an organic acid, it will help to make the coolant last longer however, it will make the metal parts wear down over time. OAT is different from IAT as it does not include phosphate corrosion inhibitors or silicates to safeguard your car. IAT coolants are still used in older cars made before the mid-1990s.Īn OAT coolant comes in a couple of different dyed colors ranging from dark green to orange. You should flush out IAT coolants from your car’s system once every couple of years or 30,000 miles. It contains phosphate corrosion inhibitors and silicates that safeguard the metal parts in your cooling system. It is a clear coolant that is dyed green so consumers can identify what it is. Used from the 1920’s to the late 1990’s, IAT coolant is used most often in United States-manufactured cars. Here are some tips for choosing the right coolant, and some coolant reviews to help you find the right coolant/antifreeze for you.įree of nitrites, silicates, borates, and amines, this antifreeze is the best general-purpose coolant at a reasonable price. When you are purchasing coolant for your car, it important to consider how often you flush out the coolant, what types of additives you like in your formula, and what will help you protect the metal in your cooling system while stopping corrosion. There are actually three different types to choose from, and they are each created in different ways.

“On its website, the company now also warns owners to consult their vehicle ‘owner’s manual for the type of coolant right for your vehicle’ and never ‘mix one type of coolant with the other.Buying the right coolant / antifreeze for your car can be trickier than you think. I also find instances where GM warns not to mix Dexcool with other coolants: I have seen too many stories about head gasket problems that only manifested themselves after the coolants were mixed. In order to change back to DEX-COOL however, the cooling system must first be thoroughly drained and flushed.” ( )

“If the coolants become mixed with Dexcool?, however, one study showed a possible aluminum corrosion problem in certain situations.” ( )Īccording to GM, “Mixing a ?green? coolant with DEX-COOL reduces the batch?s change interval to 2 years or 30,000 miles, but will otherwise cause no damage to the engine. After all, Dexcool is made with “organic acid technology.” ( ) Also, “the OAT (organic acid technology) will cause precipitation of silicates in the green type and corrosion protection is greatly reduced.” ( ) So this probably won’t make your coolant “turn into acid,” but it will make your coolant more acidic than it was. Maybe “acid” wasn’t the best choice of words, but when you mix additive packages and rust inhibitors, you never know how they are going to react.
