What are the three types of antifreeze?
Today, automotive service providers use three basic types of engine coolant:
- • IAT – Inorganic Additive Technology.
- • OAT – Organic Acid Technology.
- • HOAT – Hybrid Organic Acid Technology.
- • Hybrid and Electric Vehicle Cooling Systems.
Does it matter what type of antifreeze I put in my car?
Well, you use the coolant that is specified in your owner’s manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer’s maintenance schedule.
What do the different colors of antifreeze mean?
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
How do I know what type of antifreeze to use?
Your car’s owner’s manual provides a wealth of information. It will tell you what type of coolant is best to use in your vehicle. If you don’t have a copy of your owner’s manual, you can most likely find the information you need online.
What color of antifreeze should I use?
Fresh antifreeze is a clear brightly coloured liquid, usually blue, red, green, violet, yellow or orange but this will vary depending on the manufacturer’s formulation. Over time, your coolant will become dirty losing its colour and becoming darker, often an oxidized shade of brown.
Does it matter what color antifreeze you use?
The truth is, color is not a reliable predictor for what type of coolant you have.
What are the two common types of antifreeze?
The most common water-based antifreeze solutions used in electronics cooling are mixtures of water and either ethylene glycol (EGW) or propylene glycol (PGW). The use of ethylene glycol has a longer history, especially in the automotive industry.
Is all antifreeze the same color?
What colors does coolant come in? Variations of coolant/antifreeze can come in; pink, red, orange, blue, green, and yellow. This can make it confusing when trying to decide which coolant you need in your vehicle. The different colors can mean different properties of the liquid.
Can you mix green and yellow antifreeze?
You can mix two different colors of the same kind of coolant without any problem whatsoever. But if you mix a significant amount of one type in with the other type, you’re weakening your corrosion inhibitors (it happened to my brother, and look at the condition he’s in now).
What color is universal antifreeze?
Traditional North American “green” antifreeze, the original “universal” formula that everybody used until the introduction of today’s extended-life coolants.
Can I use green antifreeze?
Green Antifreeze Green engine coolants are designed for use in older cars (think pre-2000), ones that contain a lot of steel and copper components in the cooling system. To protect these metallic parts from rust and corrosion, Inorganic Additive Technology (IAT) gets added to the mix.
What is the best antifreeze for vehicles?
EVANS Cooling Systems High-Performance Waterless Engine Coolant
What is the best brand of antifreeze?
– Formulated to replace the OEM fluid in Asian make vehicles such as Toyota , Lexus , Scion and others requiring a red, silicate free HOAT antifreeze/coolant – 5 year/150, 000 mile . Silicate-free, long-life, phosphate Hybrid Organic Acid Technology chemistry – The long life formula provides protection for all cooling system metals from rust and corrosion.
What are the different types of antifreeze?
Water. Almost all engine antifreeze is made up of 50% water.
What kind of antifreeze do you use in a car?
