I have an I4 in my 85 westy.  When I installed the plumbing (Coolant
hoses), I cut off the ends (about 4 inches/7.5 cm in length) of the very
long & curvy hoses (from the 1.9 WBX) that normally were attached to the
2 large diameter hoses that go to the radiator at the vanagon front.  I
estimate that the outside diameter on the hoses is about 2 inches/5 cm
where were attached at the "firewall."  These hoses immediately reduced
down to a smaller size diameter, to about 1.5 inches/3.5-4 cm.  I would
like to replace these hoses soon, as they are older than the rest of the
hoses.  These 1.9 WBX hoses are very expensive (parts 025-121-062 and
025-121-102), so I would rather find a similar replacement that is less
expensive and less wasteful.  These hoses are also getting harder to
find and I would rather leave them for those who still have the WBXs.
Can any of you engine conversionists suggest an appropriately sized
replacement?

 

I can get better measurements of the hoses tonight.
