My local VW dealer can only supply G13 coolant.....is it safe to use in a '92 G40?
The parts man says yes it's fully compatible. ..but that isn't quite the same as a recommendation.
Any thoughts please?
The current coolant will be flushed out as part of the water pump replacement.
Thanks, Peter
If it was me I wouldn't I've been told not to the ally head don't like it , I use prestige universal from Gsf works well haven't had any problems and been running it for 2years ( is g13 the red one or is that 12 ? Gs Come with g11 originally
I use blue coolant. The red stuff seems more corrosive from personal experience.
I'd say use it. VW coolant has always remained primarily the same.
The last I heard about changes in the coolant is just for newer engines and relates to emissions control and engine warming that is a lot closer monitored on mk7 Golf's (the platform everything VW test's on)
Blue coolant is a certain no in VW engines, blue coolant eats VW aluminium heads massively, the pink coolant is made to prevent this. You are also meant to use de-ionised water with VW pink coolant :)
I've always like VW coolant, anything else I picked up in a rush from GSF/ECP or similar never seemed to keep a constant temp in my Golf like VW's did
You can't mix g11 & g12. g12+ could mix with either, I think the same goes for g13. I'd have no worries using it.
g11 is what they originally came with, I think that was a blue colour.
It's fine to use - I have used G13 for years now.

About the last 4 years? ;)
Thanks for the help folks. Balance of opinion seems to be that G13 will be fine as long as it's not mixed with G11 (original fill) which hasn't been available for several years now.
The big concern was based on use of OAT coolants in older engines which was said to cause corrosion in yellow metals (brass/copper) , to the best of my knowledge there isn't any in a PY engine....but lots of aluminium which is protected by the G13.
always used blue G11...
I've been using G13 for a while as well. Its pink in colour and has been fine for me.
