How do I know what type of coolant to use?
How to Check a Vehicle’s Coolant/Antifreeze
- Rather than open the cap on the radiator, just check to see whether the liquid reaches the “Full” line on the side of the coolant reservoir shown here.
- Coolant is usually red, green, blue, or yellow.
What types of coolants are used in vehicles?
There are three main types of coolant that car companies use: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Typically, older cars use IAT.
What to look for in a heavy duty coolant?
When choosing a Heavy Duty coolant, it is crucial to look for an indication that the coolant meets the 6210 standards. Coolants can also be classified based on product type. Typically type classifications are generic terms that are related to the base type and additives used in the coolant.
What kind of coolant do you use for a car engine?
This is particularly the case in some heavy-duty on- and off-road engine types, which may specify the use of OAT type coolants fortified with nitrites and/or nitrites and molybdates, but also some passenger-car engine types that specify OAT inhibitors fortified with silicates and others, or phosphates.
How are coolants classified according to product type?
Coolants can also be classified based on product type. Typically type classifications are generic terms that are related to the base type and additives used in the coolant. Although these terms can be useful in the general classification of coolant, coolants within each type will vary in composition and performance.
How does the colour of coolant tell you what it is?
“Coolants in automotive light-duty applications are dyed many different colours; the colour of any automaker’s particular coolant does not tell the technician what the formula is. It doesn’t even signify what manufacturer the coolant was OE on.

What are the different types of antifreeze coolants?
All coolant of this variety is either silicate free, phosphate free, or both, and is designed specifically to meet the needs of that particular manufacturers’ testing. What Are “All Makes” Coolants? So what exactly are the “all makes” coolants? They are HOAT – Hybrid Organic Acid Technology.
What kind of coolant is no longer used in air conditioners?
• R-22 is no longer used for new air conditioning systems, a change that became effective in 2010. • A common brand name for R-22 is Freon®. • This coolant is a hydro-chlorofluorocarbon (HCFC), a type of coolant that is no longer used because it causes ozone depletion. • Use of this coolant is prohibited in all HVAC units after 2015.
