Will the g12 turn green after being cycled through the engine? I did my timing belt last weekend and the coolant that came out of the engine was green. Im not worried now its got the pink g12 in it but just wondering.

 

red will never turn into green. someone refilled it with the wrong stuff.

our engines are made of many dissimilar metals, not only which serve as a (-) battery connection, but are subject to galvanic corrosion. G12 antifreeze is designed to stop this from breaking down all metal parts in your engine.

as the article says mixing any fluid with the G12 can break down the protective properties of both fluids. not only do you get a higher freeze temperature (bad thing) but you also may enable the metal in your engine to start breaking down again.

the broken down pieces of metal obviously cant disappear right? nope, they get trapped in the coolant and form globs of crap which clog parts of your cooling system.

 

It will always be pink. If yours is green, someone switch to domestic coolant which doesnt protect as well and will burn off causing you to keep adding more

 

are all the "pink" coolants g12???

cuz mine has a pink coolant but idk if is the g12






thanks

 

If you have pink coolant, then it should be G12. Dont know if there are any other pink coolants however

 

My VW uses G12.

I'm not sure about Audis, but for VW's, if you flush out the G12 colllant and you can actually use the neon green antifreeze.




BTW i'm new here, just popped in this section of the site because it seems more popular. I'm hoping to buy an A5 (or S5) within the next 3 months. (fingers crossed)

 

sure you CAN do that. theres a few people who have, mainly because they have heavily modified cars and are constantly taking stuff apart and want to use some cheaper coolant to easily replace what is lost. you can also run strait water as long as its not below 32* where you are.

but the point is, by running the green crap, you are circumventing the protection against galvanic corrosion that audi had in mind when they made the pink stuff OEM for these cars. its not the best for the average daily driver car.

in fact, if i were going to buy an audi, and noticed it had green fluid in there, i would raise hell with the seller and wouldnt buy it unless he knocked a ton off the price. theres no telling what other damage could have been done by a dumbass owner that couldnt even put in the correct fluid in there. he may have used conventional oil too. the radiator and engine could be full of sludge for all i would know.

 

^ again

 

I was at autozone today and i saw they did have some pink antifreeze but it wasn't g12 it was some cheap stuff for boats and rv's.

 

well i don't think you're going to put that into a car. anyone who can read knows at least that much i hope.
