[Vwdiesel] Re: radiator pressure testing

[Justin and Chelly Bennett]

Fairly low pressure system.  Start with the exhaust from a shop vac, or 
the wife's vacuum if you can plumb a line from the exhaust outlet on 
it.  Another method would be to plug one of the outlets and then rig a 
long piece of pipe on the other end.  Then fill the radiator and the 
stand pipe.  This will give you a certain amount of pressure, depending 
on how much water you have in the standpipe.  One of the sharper minds 
on the list could probably dredge up a formula to calculate this.  Don't 
exceed the amount of psi that is called out for when doing a coolant 
system pressure check on the whole system.  I think it is around 15 psi, 
but don't qoute me on it as I haven't had my cup of morning caffeine and 
numbers are suspect. (so is spelling)
