The container on my car actually mentions G13...

So, are you suggesting that, if I keep the silicate bag (or I change the expansion container with one that has it) I should not worry about? However, is a small expense in term of material (the coolant is not that expensive) and therefore I was planning to do it at the next oil change... I did not realise that is more complex than I thought. However, having always done this kind of jobs (also breaks and break fluid change on my motorbike) I was hoping to be able to do it... And in case happy to get some tools to keep for the future. I already have also the campervan that needs coolant change (that is really old, and don't know how much, since I got it second hand)... Thanks for recommendations.

Many thanks for your reply. No, I am planning to changing it because I had a bad experience of corrosion on an engine (this was a motorcycle) and I was recommended to replace the fluid every 2 to 5 years... No, I have not removed the silicate bag, but also on that I have read that might be a good thing to either replace it (together with the entire expansion) or remove it (in case it breaks is a big issue, I understand)...

Hi everyone, is it possible to change the coolant at home without special tools? Squeezing the hoses will let all air out (or will it head to the reservoir by itself eventually) or do I really need a vacuum filler tool? Thanks

Hi @LondonNeil, Is there any issue in bleeding the brakes if the car has the "hill start assist"? I mean the option that keeps the brakes on for a bit when you are starting on a slope? Or is it all as it used to be on "old style" cars? Many thanks in advance.
