CAUTION: If oil was drawn out during the recovery process, the correct amount may be added directly from the
recovery, recycle and recharge station (if so equipped) prior to the charging process. It must be stressed that the need to
protect compressor oil from moisture is vital, observe the pr ocedures in HANDLING LUBRICATING OIL and those concerning
excessive engine speed.


1. In order that the
air conditioning system may operate
efficiently it must contain a full refrigerant charge. The
indications of some system defects, and the results of certain
tests, will show that a low charge is the most probable cause of
the fault. In such cases the ch arge should be recovered from
the system, the weight noted, and the correct amount added.
Should refrigerant be added in liquid form, the engine speed
must not exceed 2000 rpm for a period of two minutes after
first running the compressor. If the engine speed is excessive,
compressor damage may occur du e to the lubricating oil and
the liquid refrigerant being initia lly forced around the system as
a 'slug', thus taking oil away from the compressor. These
marginal lubrication conditions in the compressor will cease as
the refrigerant becomes gaseous.
Never attempt to estimate the amount of refrigerant in a
system. Always recover and rech arge with the correct charge
weight; this is the only accurate method.

Features
Manufacturer - Denso Type - L3B-HE Drive Ratio - 3.04:1 Output - 120 Amps at 5000 rpm (generator speed) at 25° C
The generator is fitted at the front right hand side of the engine, to a sepa rate mounting bracket, which in turn is bolted to
the cylinder block. Two bolts secure th e generator to the mounting bracket; one is reached from above and one from below
the vehicle.
The voltage regulator is integral with th e generator body. Battery charging capabi lity has been optimised for charging a
battery which is located remotely, in the luggage compartment. The design of the generator and regulator has been finely
matched, to generate charging current with very low ripple. This provides the best electrical refinement to the system.
The generator is driven by a single, multi-ribbed belt which also drives all other front-e nd accessories; except for the
supercharger (where fitted).
No special service tools are required to remove the generator from the vehicle.

Front End Body Panels
A false bulkhead together with two insulation covers, are installed between the engine compartment and the BIW front
bulkhead to provide optimum insulation ag ainst noise and heat intrusion. Two plenum braces bolted between the BIW upper toeboards and the plenum further increase bodyshell structural integrity. The plastic ra diator grill and vane block achieve
weight reductions over steel parts and provid e high resistance to front end corrosion.
