Removal and Installation

Removal
- Disconnect battery earth lead.
- As required, depressurize the air conditioning system.

WARNING: Do not vent refrigerant directly to atmosphere and always use Jaguar approved recovery/recycle/recharge equipment. Wear suitable eye and skin protection. Do not mix HFC 134a with CFC 12. Observe all applicable safety requirements.





- Remove bolt- muffler to mounting bracket (1).
^ Torque: 47-57 Nm (34.6-42 ft lb)
- Remove bolt- muffler to compressor (2) and displace muffler assembly.
^ Torque:30-40 Nm (22-29 ft lb)
- Fit protective caps to the muffler.

CAUTION: Do not leave any part of the system, or component, open to atmosphere for longer than is absolutely necessary.

- Remove and discard compressor port "O" ring seals, fit a blanking plate.
- Release compressor clutch harness tie straps and disconnect multiplug.
- Release and remove compressor upper pivot bolt securing nut.





- From underneath, remove the lower pivot mounting bolt and drive belt adjuster assembly (1).
- Remove the drive belt.
- Support the compressor and remove the upper pivot bolt (2).
- From below, carefully remove the compressor.
- With the compressor on a bench, remove the upper support brackets and the lower adjusting strap if necessary.

Installation
- If the original compressor is to be refitted, following any rectification work, drain the oil from it into a measuring cylinder and record the amount. Flush the compressor out with fresh PAG oil and drain thoroughly. Replenish the compressor with the same amount of PAG oil that was originally drained out and plug all orifices ready for refitting to the vehicle.

- The transit lubricating oil must be drained and discarded from a new compressor before it may be fitted. An adjustment should be made to the system oil level by taking into account (a) the quantity found in the original compressor and (b) the quantity deposited in the recovery equipment oil separator from the charge recovery operation.

- Typically, 80 ml may be drained from the original compressor and 30 ml found in the oil separator; if these quantities are added together 80 + 30 = 110 ml, then this is the amount of fresh PAG oil that must be put into the compressor prior to fitting.

- Please note that the discrepancy between this figure and the nominal capacity of 135 ml is caused by normally unrecoverable oil being trapped in components such as the receiver/dryer or evaporator. The previous statements are only valid if there is NO evidence of an oil leak from the system. If oil has been lost and the fault attended to, then the compressor, whether original or replacement, should be filled with the specified quantity.

CAUTION: Always decant fresh oil from a sealed container and do not leave oil exposed to the atmosphere. PAG oil is very hygroscopic (absorbs water) and will rapidly attract atmospheric moisture. PAG oil must NEVER be mixed with mineral based oils.

- Fitting the compressor is the reversal of this procedure, noting that the compressor pivots and the adjuster should not be fully secured to torque until the belt tension has been set to specification.

- Ensure that new "O" ring seals are fitted and the protective caps are not removed until the last possible moment before connecting the muffler.
