Generally it is caused by mixing two incompatible types of antifreeze. Such as regular green propylene glycol with Dex-Cool. They are supposed to be mixable, but they turn into an orange-green mud in the cooling system.
green
You can but then the mixture will turn into gel and your entire coolant system will be ruined. If you continue driving your engine will overheat and your car, destroyed.
green
It's the pink antifreeze
I have seen pink, red, orange, blue, purple, green, and yellow. They all turn brown if not changed when required.
no.
You must drain and flush the orange before going green, and there is a chance you may not get it all. Orange plus green = sludge. It's better for the first time to drain the orange, flush the best you can, and use the universal "works with all" antifreeze. Then you can go green with any subsequent changes. You absolutely should NOT change from the orange Dexcool to green antifreeze. The green will deteriorate certain components and gaskets used in the engines that use the Dexcool antifreeze. Yes, the orange is much more expensive, but it does not require flushing and replacing very often. I would never put the green in a car that requires the orange.
it hasnt gone orange. alot of vehicles, all gms for example, use dexcool antifreeze wich is orange.you cannot mix it with green antifreeze.
green , the Owner Guide shows not to use orange
The difference between the two colors is that orange antifreeze contains a different type of corrosion inhibitor that has a much longer service life than silicates, phosphates and borates. Orange antifreeze contains organic acids that protect engine parts from corrosion. Silicate (green) type antifreeze does not mix with orange type antifreeze. Never mix the two colors in a cooling system. The organic acids in orange types will cause precipitation of silicates in the green type and corrosion protection is greatly reduced.
No it will not but don't mix it with the orange.
