radiator flushing

[flaatr@yahoo.com (Euroroc II)]

Some thing I've noticed in both my 8V and 16V is that Volkswagon uses a 
metal coupling between the hoses from the heater core and the block... one 
hose has the valve and one has a coupling. This coupler starts to corrode 
and crust up on the inside thus restricting the passage way. If you are 
flushing the system it's a good idea to pull this coupling out and either 
scrape it clean or replace it with a plastic one if it's corroded, it's 
also a good place to stick in the 'T' if you are installing the Prestone 
flush kit by the way since you don't have to cut any hoses.
