I've changed two rear heater cores that leaked. In both instances the leak
was attributable to the heater core assembly itself, not the ancillary
components. I would purchase the o-ring with the heater core but the rest
of your components should be o.k. for re-use.

Hi,
The Bus Depot lists the following parts to replace the the rear heater core
plus
the plastic end housing(s?). The cost would be roughly $120 for the parts
plus
whatever the radiator place will charge to crimp the pieces together plus do
a
pressure test. for the time being I will leave it out since I do not use the
Westfalia during the winter.
O-ring, rear heater core to valve, 82-91 Vanagon
$2.29 861 819 297
