Whats the difference between orange and green coolant?

Answer 1

Green is used in older cars, Orange in newer and Chevys, orange is modern, better and more advanced. Color dye is added to tell them apart.

Answer 2

This is why there is now different coolants. The green was fine for older vehicles due to the fact the engines were primarily made of cast iron. Later it was discovered this antifreeze was causing too much electrolysis (corrosion) in the newer engines because they started using aluminum intakes. The two dissimilar metals cast iron and aluminum being the softer of the two will pit and after time dissolve. As water moves through the engine it creates static electricity, this is actually what kills the aluminum parts. Now the orange and pink were designed to slow the electrolysis process down and this is where the car makers say you can use this new antifreeze for 5 years.

Seeing the cost of the car and how cheap the coolant is, I would use the orange long life and change it every two years any way.

Answer 3

The regular green antifreeze has been around for years, and is recommended to replaced yearly..but now since 2001 most new cars have coolant that last for 5 years, that could be orange or pink, depending on if it is a domestic or import...Either way, you can not mix the two coolants together..your car should have a sticker under the hood telling what coolant is recommended for you vehicle...

Answer 4

The green stuff is called ethylene glycol and last around 40,000 to 60,000 miles. It is used by Ford and most other car manufacturers. The Orange stuff is called Dex-Cool, it last about 100,000 miles. GM and maybe a few others use it. Dex-Cool cost way more than the green stuff and many people say it's not even worth it.

Answer 5

i own a repair shop,and there's a lot of difference in it,,the orange is environment safe,and the green isn't,the orange wont harm animals if they drink it,,the green will kill a cat or a dog within 24 hours if they drink it,,and also the two wont mix well together ,,they know have a green that will mix with it,,but the older green wont mix with it,,it makes it look like it had mud in it,,this is the difference in the two,,good luck hope this help,s.happy new years.

Answer 6

They are two different products which can cause corosion if used together. The Dex-Cool or orange coolant is formulated to give you longer protection in high temperature motors and if your car came with it you will certainly void the warranty if you switch or mistakenly add regular to it.
