Here are some crib notes for you. BASF did the fundamental engineering on Euro OEM and two common American coolants made here under license: DexCool and G-05. Also, I have the MSDS for G 12, got it from the VW dealer.


VW G-12

name % CAS
ethylene glycol 70-80% 107-21-1
diethylene glycol 10-20% 111-46-6
sebacic acid 1-5% 111-20-6
sodium hydroxide 1-1.5% 1310-73-2


Here's a recap of BASF's families of coolants followed by URL's for some of them. Notice there are three DexCool type coolants, G 30, G 33, and G 34

Nitrite- containing, amine-, phosphate-free:

G 05 - Universal use for all types of engines

007/400 F - Specially for Rover and Rolls Royce, approvals by Detroit Diesel, Cummins, Perkins

G 206 - Approved by MAN (for use in arctic regions)

Nitrite-, amine-, phosphate-free:

G 48 - Universal use for all types of engines e.g. Mercedes-Benz

G 51 - "Fighting grade product" with basic corrosion protection

Nitrite-, amine-, phosphate-, silicate-, borate-free (OAT):

G 30 - New generation of coolants e.g. for VW (see approval list)

G 33 - Approved by Peugeot, Citroen

G 34 - Approved by Opel/GM Europe, Saab

Nitrite-, amine-, phosphate-free Propylene glycol based:

Basin P 43 - Universal use for light vehicles and heavy-duty engines, applied in countries with special legal requirements

Engine coolant Super Concentrates:

Engine coolant Super Concentrates contain higher concentrated inhibitor packages than the normal Glysantin types. They have to be blended by the customer with monoethylene glycol according to a specified blending procedure to obtain engine
coolants that are conform to the product specification. Super Concentrates are available for Engine Coolant G 05, G 30 and G 48.

Super Concentrate G 99 + MEG --> Engine Coolant G 48

Super Concentrate G 102 + MEG --> Engine Coolant G 05

Super Concentrate G 106 + MEG --> Engine Coolant G 30

and spent twice the $ hunting down G12+ and flush all my G12 to G12 Plus? Or should I just top it off with some G12 and call it good(replacing thermostat)? The current fluid was drained/refilled abut 18 months ago.

I know G05 is prob a good choice too, in fact I use it in my family's MB E320. But I really want to stick with G12/G12+.

So I don't ever need to set my foot in a Audi/VW dealer again! ........until something breaks.

with water? no

Haha, G-05 has the longest sucessfull track record. Unsilicated coolants blow TBelts via waterpump.
