 I have a mechanic who does this on the side....he was trained in
Germany and France.  He says you need to use 100% coolant.  He has done
this for yrs and never any problem with heads.  I told him coolant
directions say 70 or 50% water with coolant.  He advised me to NOT
follow these directions and only use full coolant as it's the water
that causes the problem.  Also he has a different perspective on air
bubbles.  Dealer and other VW mechanics say to raise front end 12
inches when doing coolant change.  According to this guy...that is
wrong!  He says you need to raise back of vw...reason being that air
bubbles rise to top...that way the bubbles will rise...bleeder value is
in back and that way you can get air bubbles out.  He's been doing this
for years and again...never has had problems with air bubbles..

Anyone ever heard his perspective before?
