Range Rover P38 # 062 - AC System Fix +

It's been a while since the last video, but here's todays project: Trying to fix the AC which has been diagnosed as a leaking condenser. I'll replace the AC switch and AC tri-pressure switch along with the dryer / receiver. That means almost everything in the AC system is replaced and should give many years of service. Refilling the system is rather expensive here so it's always good to make sure something else don't fail and require a refill again.

The battery box needs to be removed to gain better access to the lower intercooler bolts. The intercooler must come out first. Then the AC condenser can be removed. The dual fans are moved from the old condenser over to the new one.

To access the dryer and switches you need to remove the front bumper. It's rather easy except if the side brackets have rusted in place. To remove the dryer/receiver I find it easiest to remove the auxiliary fan and loose the auxiliary radiator to bend it slightly out of the way.

The whole process should be done in 3-4 hours depending on how rusted / corroded your bolts and pipes are.

Make sure to replace all the o-rings, lubricate them with compressor oil and avoid getting debris or moisture into the lines.

I prefer to put the condenser back in first, then the dryer/receiver unit with all switches and pipes to avoid getting debris into the system.

AC condenser part # STC3679 (I used a Hella aftermarket unit)
AC dryer / receiver part AWR1374
AC switch BTR9223 (comes with o-ring)
AC tri-pressure switch JTB100370 (needs o-ring JUU100100L)
2 x o-rings JUU100100L
3 x o-rings JUU100220L

The system uses R134a and takes 1100 g ± 50 g.
For an empty system add 140 cm3 compressor oil type ND-OIL 8.
