antifreeze, red/pink or blue/green?

[MGaz]

quick question, so i can pop to the shops tomorrow and get some, What is the right colour antifreeze for my AEL? It has an alloy head yea? so i'm guessing pink/red? as this one has anti corrosive properties for aluminium?

And also, what ratio would you guys recommend?

i use the blue one, but you may use the red one; but NOT mix them... and you want to change type( color) you need to flush the system properly

I like mine pink. It was brown before. Which i didnt like the look of so much. Smelt funny. Pink keeps it clean. Pink all the way.



I used Audi's g12++++ or whatever its called these days. Its very good.

ok so the consensus is pinky red colour?

but one person is saying G12 and the other G20?? now i'm confused. what do the different numbers mean? is one just better? and will any pick stuff do? There is no Audi dealer in my local town any more, even VW has gone now But Motor-mania do a pink anti freeze. does it matter so long as its pink?

Febi make a miscible alternative to the G12, its about 1/2 the price and GSF stock it

antifreeze

I have used Comma antifreezes in all types of cars for years - never had any problems, it's easy to obtain & excellent value

Red/Pink stuff only. If you have blue anti freeze in there make sure you flush it all out first, specifically engine block and heater core. Also dont use tap water to mix it with, buy distilled or battery water, its cheap and clean of minerals and other contaminants.

red or pink it is all the same.
if you put more wather than red will became pink
ETKA said : G12 for our audis.
BUY g 12 , and it will be perfect.

when I bought my audi I put blue one in engine , and than after 3 days my head gasket burn , and I have to change it.
can that be caused by antifreese ? or it was coincidence?

after that I always use G12 (red or pink )

[MGaz]

well i've bought some pink anti freeze today, says it meets G12 on the back.

I also bought some oil, 5 litres of Mobil 1 , turbo diesel 2000 semi synthetic 10w 40 , & it says it meets 505 standard on the back? I hope it will be OK

Now my next problem, how do I get the plastic underfloor off so I can get to the radiator hoses and the sump plug ?

had a quick look and the back of it seems to be held on with cable ties.

is G11 any good? and can g12 lower the temperature? thanks.

What's wrong with the blue stuff?

The plastic quarter-turn clips that should hold the tray on break easily so very few cars will still have a full set by now. Many folks use cable ties as a replacement which obviously you'll have to cut off and replace each time you take the tray off.

There's nothing wrong with the blue stuff, it would have been the factory fill when our cars left there it's just that it only lasts 2 years before you should replace it whereas the red G12+ will last 5 years or more.

According to some websites the red stuff shouldn't be used in engines with any brass in them. Whilst I do use G12+ in my engine I also note that the radiator fan switch insert in the bottom of the radiator is brass as is the MFTS IIRC.

You certainly don't want any of the blue stuff left in if you switch to red. There's posts on the BMW forums (as if we care ) of owners with older cars switching from blue to red and having problems with water pump seals etc.
