Title: Coolant advice
Post by: Lyons on December 12, 2010, 05:28:51 pm
Folks, can someone educate me on the various coolants available?

Basically the book says G12 plus or TT VW 774F, but I went to Halfords there and all they had was TL774D and TL774F.

Out if curiosity can any of them be mixed?

Do both G12 plus and TT VW774F need diluted? I assume neither comes ready to fill?

I was told that for topping up, so long as you use the same colour, i,e - red it will be fine.

That's what I use and no problems with all the cold experienced of late  :happy2:

Hi bought a 1.5ltr bottle of 'G12 plus plus' (the latest one) from my local main dealer (Stoke VW) and it came to about £8.50. The G12 plus plus is fully 'miscible' (compatible) with G12 and G12 plus too!  :happy2:

Got the G12 Plus (actually Plus Plus) today and topped the bottle up.

I'm a bit concerned as to why it would be low though. My immediate thought was a leak, but can it just get low naturally?

Make sure you dont mix G12 Plus Plus with other red coolants.  If you do then it will go a nastly brown and stain the bottle and can go sludgy.  VW have done this to show when non VW coolant has been used.
