Climate Control System - General Information - Electronic Leak Detection
General Procedures
1. WARNING: Good ventilation is necessary in the area where A/C leak
testing is to be carried out. If the surrounding air is contaminated with
refrigerant gas, the leak detector will indicate this gas all the time.
Odors from other chemicals such as antifreeze, diesel fuel, disc brake
cleaner, or other cleaning solvents can cause the same problem. A fan,
even in a well ventilated area, is very helpful in removing small traces of
contamination from the air that might affect the leak detector. Failure to
follow this instruction may result in personal injury.
Attach an R-134a manifold gauge set or use a UL-approved
recovery/recycling device such as an R-134a A/C refrigerant center (which
meets SAE Standard J 1991). For additional information, refer to the
manufacturers equipment instructions.
Both gauges should indicate 413-551 kPa (60-80 psi) at 24°C
(75°F) with the engine off.
If little or no pressure is indicated, carry out the air conditioning
(A/C) system recovery, evacuation and charging procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.
2. Use an R134-a Automatic calibration halogen leak detector to leak test
the refrigerant system. For additional information, refer to the
manufacturers equipment instructions.
3. If a leak is found, carry out the air conditioning (A/C) system recovery
procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.

Climate Control System - General Information - Fluorescent Dye Leak Detection
General Procedures
1. WARNING: Eye protection glasses supplied with the ultraviolet (UV)
lamp should be used to protect eyesight from harm.
NOTE: The air conditioning (A/C) system has an R-134a leak trace
dye wafer incorporated into the desiccant bag. The exact location of
leaks can be pinpointed by the bright yellow/green glow of the tracer
dye. Since more than one leak may exist, always inspect each
component. If it is necessary to add dye (due to a severe leakage for
example) use proprietary tracer dye injection equipment.
Check for leaks using ultraviolet (UV) lamp.
2. Check all components, fittings and lines of the A/C system.
3. Carry out the repair. For additional information, refer to Section 412-03 Air Conditioning.
4. After the leak is repaired, remove any traces of leak trace dye with a
general purpose oil solvent.
5. Check the A/C system for correct operation.
6. Verify the repair by operating the system for a short time and inspecting
with the (UV) lamp.

Climate Control System - General Information - Inspection and Assembly Requirements
General Procedures
1. Check for leaks using ultraviolet (UV) Lamp.
For additional information, refer to Flourescent Dye Leak Detection in this section.
2. NOTES:
Any time a hose or component connection leak is observed, the
component and fitting must be separated, cleaned and a new O-ring
fitted and lubricated with air conditioning compressor oil.
For additional information, refer to Specifications in this section.
When separating A/C joints, cap the open connections
immediately. Do not leave open to atmosphere.
O-ring seal surfaces must be free of dirt, lint, burrs and scratches. The
O-ring and connector should be lubricated with air conditioning
compressor oil.
For additional information, refer to Specifications in this section.

General Procedures
1. WARNINGS:
Use extreme care and observe all safety precautions related to the
use of refrigerants. Failure to follow this instruction may result in
personal injury.
For additional information, refer to the manufacturers equipment
instructions. Failure to follow this instruction may result in personal
injury and system damage.
Install the manifold gauge set. For additional information, refer to the
manufacturers equipment instructions.
2. Carry out the repair.
3. Remove the manifold gauge set. For additional information, refer to the
manufacturers equipment instructions.
4. Carry out flourescent dye leak detection test.
For additional information, refer to Flourescent Dye Leak Detection in this section.
5. Check air conditioning (A/C) system for correct operation.

Climate Control System - General Information - Refrigerant Oil Adding TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol
General Procedures
CAUTIONS:
Collect the refrigerant oil in a clean measuring cylinder. Check
Make sure that all openings are sealed. Use new blanking caps.
Be prepared to collect escaping fluids.
NOTE: Removal steps in this procedure may contain installation details.
1. NOTES:
This step only needs to be carried out when replacing
the A/C compressor.
Some variation in the illustrations may occur, but the
essential information is always correct.
Torque: 15 Nm
2. NOTES:
This step only needs to be carried out when replacing
the A/C compressor.
Some variation in the illustrations may occur, but the
essential information is always correct.
Rotate the A/C compressor shaft at least 6 to 8 turns when
draining the refrigerant oil.
3. CAUTIONS:
The refrigerant oil top-up quantity must not exceed the refrigerant
oil fill quantity.
If other A/C components are being renewed in addition to the A/C
compressor, there is no need to top up with additional refrigerant oil,
apart from filling the compressor.
Top up with the calculated quantity of new refrigerant oil.
Refer to: Specifications (412-00, Specifications).

General Procedures
1. WARNINGS:
Use extreme care and observe all safety precautions related to the
use of refrigerants. Failure to follow this instruction may result in
personal injury.
The A/C refrigerant analyzer must be used before the recovery of
any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant
at risk of contamination. If the vehicle A/C refrigerant is contaminated,
refer the customer to return to the repair facility that carried out the last
A/C repair. If the customer wishes to pay the additional cost, use the A/C
recovery equipment that is designated for recovering contaminated A/C
refrigerant. All contaminated A/C refrigerant must be disposed of as
hazardous waste. For all equipment, follow the equipment manufacturers
procedures and instructions. Failure to follow this instruction may result
in personal injury.
NOTE: Jaguar Land Rover Limited supports the efficient usage,
recovery and recycling of the refrigerant used in passenger car air
conditioners. Jaguar Land Rover Limited recommends the use of
UL-approved recovery/recycling device such as R-134a A/C refrigerant
center (which meets SAE Standard J 1991) during any A/C system repair
and recharge procedure which requires that the system be evacuated.
Use R-134a A/C Refrigerant Centre to evacuate and recover the A/C
system.
Follow the equipment manufactures procedures and instructions
for use of equipment.
