Coolant Silica Bag Issues

How does the long life 8 year coolant work in the stores? Or it doesn't?

Are you talking about the Penrite red and purple coolant. The Penrite website says I should use the purple one in my 2016 B8 Passat. However it also says I would need to do a full flush of my G13 coolant before adding their purple coolant.

I put the same green colour in my XR8 not long ago. 8 years it said, that's all I know. Coolant seems to be lasting longer these days with silica bags. I never knew those were in use.

We pulled the original expansion tank out, and put in the latests OEM tank without the silca bag - topped it up with G13 and will flush after holidays with G12Evo. Been a learning process thats for sure ! thanks for the help
