Yes, I have done this on our 1986 Syncro Westfalia. I assume that the
plumbing pretty much the same on your '84.

It turned out that I also had a slow leak from the hose to the rear heater.
This leak was caused by the DPO who had obviously used vise grips on the
hose and caused a row of pin hole leaks where the jaws gripped. So my advise
is to pinch off the 3 hoses to the "T" with something that will not cause
damage to the hose. I used pieces of wood and "C" clamps. Now you can take
your time and the amount of coolant lost (and air entrapped) is small. I
used a hot air gun to soften the hose ends to aid in inserting the "T" and
to get a good seal when tightening the hose clamps.

Not, just awkward.

This is a VW specific part whether dealer or after market.
