What color is Dexcool antifreeze?
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.
Although both the green and orange antifreeze are ethylene glycol-based, the difference between them is that they contain different corrosion inhibitor ingredients or additives. While orange antifreezecontains organic acids, green antifreeze has additives, such as silicates, borates and phosphates.

- If you're looking to change your coolant, make sure you flush your radiator system a couple of times and then add Prestone (or any other regular coolant). A sidenote: if you're ever using water with any coolant of yours (yes, diluting coolants is no problem) and if you're using G12, please use distilled water only.
Antifreeze, also known as coolant, is a bright yellow or green liquid that mixes with the water in cars, trucks and other vehicles to keep the radiators from freezing or overheating. Made from either ethylene glycol or propylene glycol, antifreeze and coolant change the freezing and boiling points of water.
- OAT coolants are currently easily available from most auto parts stores. Hybrid Organic Acid Technology or HOAT: This coolant is usually dyed yellow but comes in other colors like green, pink, blue, red and orange, which leads to a lot of confusion.
- OEM Extended Life BLUE Antifreeze/Coolant meets or exceeds performance requirements ASTM D3306 and JIS K2234. This long service life product is based on a proprietary extended life corrosion inhibitor technology that is free of silicates, borates, nitrites and amines.
- It is the toxin ethylene glycol that makes antifreeze lethal. It does not take a significant amount of ethylene glycol to cause fatal damage to the system; less than three ounces (or 88 ml) of antifreeze is sufficient to poison a medium-sized dog. Antifreeze poisoning affects the brain, liver, and kidneys.
