OK, here is the latest scoop, I have decided that the 3 inch hose that goes
from the oil cooler to the metal line is way too hard to replace, I simply
ran some 5/8" heater hose from the thermo housing to the oil cooler, and
routed it very close to the metal hose. This seems to have worked good, I
disconnected the big hose from the plastic tube in font of the right rear
axle, and drained all that I could from there, then put the garden hose into
the plastic line and blew hard a few times, then did the opposite direction.
The water wouldn't flow through the system, I somehow think that it
shouldn't. anyway I drained coolant from the lowest point that I could, but
I am sure that I didn't get all the old out, (which was only 1 month old) as
I only was able to fit about a gallon and a half of pre-mix in there. The
old coolant was prestone orange and tap water, the new was VW and distilled
water, I guess there is now a mix of the two, although it looks quite blue
after circulating for a half hour in the expansion tank. I had the van nose
up in the driveway, and ran it for about 30mins, burping the expansion tank
as I went, and the burp screw at the top of the radiator, then I went for a
quick drive and all seemed well. I see no leaks, go ahead and let me know
where my problems lie now :-)
