Tech-All-Changing coolant to avoid head corrosion

["New Dimensions" <turbotim@newdimensions.com>]

Ok here is the scoop on the 2 different coolants and the VR6 
corrosion problems. 

Blue G-48 - ZVW-237-105  older fluid used in most of the VW's till 
96-97. Recommended to change every 2-3 years. If you own a VR6 model 
recommend to change to the new G-12 coolant.

Red G-12   G-012-A8D-A1  The NEW stuff. Suppose to be the solution to 
the corrosion problems. Use on the late models and Audi's. Lifetime 
Coolant (ok change every 4 years or so) This stuff is incompatible 
with any other coolant including G-48. Can be used in all other 
models but you must flush out the old stuff really good. Recommend to 
drain old stuff fill with water and run a few days then repeat it and 
after the 2nd time drain system completely. Then refill with G-12. 
All VR6 owners are recommended to change to the G-12 as the corrosion 
problems are causing expensive repairs as the VR6 fleet gets older.
