Kevin,
I recall getting lost near Empson on our way out to Newcastle, Emlyn Wales a few years ago. You know you are really lost when you see signs "Tank Crossing" along the way.


R&R of the 930 hose set is a 1 day job. Tedious, a bit dusty when the debris falls down, however an easy DIY project.

In preparation you will need:
4 jack stands,
1 floor jack,
common metric and inch wrenches and boxes,
vacuum cleaner for the stuff that falls down,
safety glasses,
6 pints of Good King Henry or Thornbridge Bracia,
no refrigerant in system,
removal of LH front and RH rear tires,
drop the splash pan under the cross member (do this with the vehicle
on the ground; just reach underneath, drop it, re-attach 2 allen bolts
to hold sway bar strap in place),
complete set of LHD or RHD hoses,
o-ring set,
receiver drier,
refrigerant oil (PAG or Ester) if you are recharging yourself.
Some hose suppliers provided detailed instructions

Other things to consider:
A) Reseal kit for compressor if its internals look good.
B) Removal and cleaning evaporator and resealing it in box.
C) Adding a 7-10 amp inline fuse to the front condenser blower motor
D) Incorporating in a low high pressure switch (some hose suppliers
provide this feature)
E) Maybe a few modest upgrades depending upon your climate and needs;
evaporator, front condenser, vent, etc.
F) If you are going to do the job best to do it right the first time rather than
revisit.

Evacuation Charge and Test
If you have AC experience and the equipment, you can tackle these procedures,
else leave it to a shop that has those assets.
