Default G12 compatible coolant

Is there a common coolant available that is compatible with VW G12 for a top off?

How much coolant is actually needed??

Fill the bottle using distilled water to the lower line on the bottle now (measure how much you put in) then add that same amount of straight G12 when you can get your hands on some. The very slight temporary dilution won't be an issue.

I thought G05 was similar to G11, which shouldn't be mixed with some versions of G12?

Valvoline/Zerex is licensed to use the BASF formulation for Glysantin G-05. Glysantin G-05 is a HOAT coolant with no 2-EHA (2-ethylhexanoic acid). 2-EHA is the additive in Dex-Cool and caused the Dex-Cool sludge problem.

Glysantin G-30 is the green/blue coolant to mix with the older generation coolants.

Here's a great article with a color table.

Pentosin does make both a G11 and a G12 compatible anti-freeze which some NAPA parts stores carry.

http://pentosin.net/f_antifreeze.asp
  • PENTOFROST NF (with silicates) (For G11).
  • PENTOFROST SF (without silicates) (For G12).

no. Was just done by previous owner 40 000 kms ago. have paper work to prove it.
Long story short, I had a training school working on my car, they left a clamp off a coolant hose. While doing an Italian tune up, hose blew off. Did not notice all the smoke behind me till doing the second wot run. I have to assume running the pump without coolant smoked it.
