Engine cold, you will loose very little coolant swapping the temp II
sensor. Good to have a catch pan handy though. One might use the
O-ring over again but that's a cheap part and wise to replace with the
new sensor. Good to have several new ones on hand too IMO.

Sometimes the wires to the temp II connector can be old and brittle so
repairing those can make the job longer. If the connector is old and
brittle, I gather that's something that can be found in the bone yard
on other similar vintage VW's.
