Ive been doing some searching for answers to this question, but finding some of what I am looking for
is in 5-10 year old posts. I know things change with time so I hope you don't mind me starting a new thread
on a well covered topic.

I have a 2013 2.0 CKRA TDI that has been leaking an intermittent, small amount coolant in the timing belt area.
after some investigation I was pleased to find that it's just coming out the water pump weep hole. This car is about due for
what I believe will be its first timing belt change anyway, so this is good news to me. After looking at the coolant I am noticing
what is in the system now appears to be the Prestone type "all makes, models & years" it has the mostly transparent yellow color
that I have noticed this type of coolant is.

It seems obvious the coolant has been changed at some point, but I have no record of what it was changed too, or why it was changed
in the first place. I am going to look and see if there is evidence that the heater core was replaced, If I find the oem heater core is still in place, it seems like a no brainer that this would be the time to install a new one.

So what is an ok coolant to use on these aging TDI's in 2014? Are these newest Prestone types safe to use today, or is it still best
to stick with the Peak or others European pink G12 or G13?

Did some more searching last night & found another thread here that included a youtube video link that talked about the VW coolants & it helped me understand whats was going on with the G12-G13 I created a link for anyone in the future who has been sitting puzzled like I have been.
I have been a car guy for many decades, but this is my first VW, so I have been learning a few things I did not know about the coolant.

I will say though, it sounds like the G13 type has been around since before 2013, so if this is true I am still wondering why the tank & manual of this car I have says G12. What I have decided to do is flush out the system best I can, Then fill with Peak Purple which sounds like is the G13 equivalent.

VW coolant discusion on Youtube

I made the link start at the point were they chat about VW coolant. Same video from the other thread I found, I just jumped it ahead.
Actually the whole video is interesting. :)
