For WBX's

For Diesels

Could splosh it in here and I'll get it formatted up and posted for you,

Many thanks

Yes, that is always the best, gives highest frost cover than any other dilution and anti-corrosion ditto (the imp. bit in these mild times)

Best mix it up in a clean pail or watering can first, then it can just be administred as required into the header tank (blue/black cap) either directly or via funnel with long flexy hose, or just through a hose on the can's spout..

Sometimes this is best a 2-person job, as engine may be running and fron needing the odd bleed, or accelerator the odd shove up to 2,000 rpm to keep thewhole procedure going well...

Header, not top-up, fill the header which is usually inside engine bay on the right, proper cap blue... old maybe black.

Clear cap is the top-up tank, disconnect that or leave it open, once header is full and system 90% bled can pu cap on and set level in top-up tank

I read on another forum that in no way should you mix the old (blue/green) and new (pink/red) type of coolant as they are incompatible and react badly with each other and form a brown gloop that will certainly kill your engine.

Thanks, but is it true?

Vw green antifreeze part number ZVw 237 105 is no longer supplied. It is replaced by the blue, red or pink, or purple antifreeze. Note: You should not mix blue, red or pink, or purple coolant with green antifreeze. If you have, you must flush your Vw cooling system.

I herd the main difference between 12 and 12+ was the colour, to stop G12 getting confused with a silularly coloured but incompatable antifrease used by another manufacturer (GM?). Dunno if its true but it sounds plausable, especally if such a mestake could cause a warantee claim on a new car.

I've just got my van back from the garage and they only used 3L of anti-freeze saying that's the VW recommended mix - is that correct and is the 50/50 mix an owner recommendation based on experience?
