No A/C
Sooner or later, it had to happen. NO A/C in a
2000 LR Disco II with 115k. Charged the system
via the low pressure port with 134A with
tracer and found the leak in the high pressure
line close to the dehydrator. The leak was
caused by a corroded aluminum line as it
passed thru the bulkhead between the left
front headlight and the radiator.
Removal was difficult because of the stiffness
of the aluminum line. British Atlantic was out
of stock of this item.
The fix, (2) 5/16 compression union, 5/16
brakeline, 11/32 drill, 4 cans of 134a with
tracer dye, and blacklight. Above items
except the drill available from automotive
store.
LR uses metric ie 8.5mm lines. The compression
fitting had to be drilled out to 11/32 to accommodate
the 8.5mm line.
I tried welding the aluminum lines but the
corrosion was so bad I couldn't get the welding
to seal. In retrospect, I should have used
5/16 copper air conditioning line instead of the
aluminum brakeline . It would have been
easier to work with.
notes:
.3346 = 8.5mm
.34375 = 11/32
Ah! Cool air again!!

Thats funny, i had the same line fail on my 01 dII, just last week. in the the same spot. i bought one used from a nice guy from the LLRF for 40 buck plus shipping. worked great.
I bought some new o rings from the land rover dealer here in town. then i had a recharge done evacuating the system first. it was on a vacuum for 1 hour. A/C works great now.
good luck.
