Coolant type

[fla 9]

I kow we should use G12+ in teh system, but if the system is drained completely, rad flushed out and the block fluched, would there be any reason not to use a generic coolant in the same ratios as the G12+? I would imagine that any G11/G12 previosuly used would be cleaned out so there would be minimal risk of any sludge etc forming? Thoughts?

We have gone over to G12+ completely, just keeping G11 and G12 for topping up systems. If we do a change, we go over to G12+ and mark the coolant tank to show this has been done. G12+ can mix with G11 but G12 can't.

No point using anything else really, it's no more expensive than the generic stuff, same with the screenwash - the VW stuff is actually cheaper than Halfords...

It is alleged that G12+ lasts much longer without changing. Depending on what you read this ranges from 3 years up to life of car. :?

 

For the past 30 years in my experience, changing of coolant has had to be about every year or two, so this news about G12+ is very welcome. However, scepticism about such claims is never totally diminished until we have several years experience of the new thang. I recall oil changes at 3k miles and many keen people - some of 'em on this forum - probably stick closer to this than the 10-20k type intervals that are so well known now.

 

Anyone know the VAG recommendation for change intervals for G12+?

VAG say G12+ is for life (there used to be a coolant called Forlife) which really means ten years. As most modern VAG products run the cam belt on the water pump, it will get changed ever four years anyway, hopefully!

Grateful for that input, Crasher. 8)
