GLOSSARY OF TERMS
Introduction
This glossary of terms is intended to cover both general and emissions-related (to SAE J 1930) terminology. It is in- tended to enable the user to ascertain the meaning of standardized terms and acronyms used throughout the Manual.
The required term may be looked-up in the left-hand column, and subsequent columns give the standard abbreviation
or acronym, definitions and previously used terms, as applicable.
As this Manual is a world
-wide publication, and must comply with certain Society of Automotive Engineers Standards, it has been necessary to adopt the terminology etc. demanded by that Standard.

Engine (AJ16)
liter supercharged engined vehicles are equipped with the AJ 16family of six cylinder in-line engines. The engines have a fully mapped engine management system with digital ignition and
individual on-plug ignition coils.
This section describes the service procedures to be carried out with the engine in situ.
It also covers the renewal of the engine / transmission unit.
For information relating to strip

3.1.2 ENGlNE/ TRANSMlSSlON UN/& RENEW
SRO 12.41.02/20
The engine/transmission unit on the AJ 16 normally aspirated and supercharged engined vehicles are fitted ontothree
engine mounting/bracket assemblies. The two front engine mountings for the 3.2/4.0 liter normally aspirated and the
4.0 liter supercharged engined vehicles are identical. They are fitted to the front crossmember on either side of the
engine bay. Rubber to metal
engine/transmission rear mounts used for both engine types, are secured to a support
bracket which traverses the two body underframe longitudinal members. For access to remove the engine carry out the following procedures:
WARNING: WHEN WORKING WlTHlN THE ENGINE COMPARTMENT, KEEP CLEAR OF THE RADIATOR COOLING
FANS AS THEY COULD START WITHOUT WARNING EVEN IF THE ENGINE IS NOT RUNNING.
. Remove the hood, see SRO 76.16.01, section 13
. Remove the air cleaner assembly.
. Depressurize the fuel system, see SRO 19.50.02, section 5.1.
Disconnect the battery.
. In line with the relevant SRO's and sections, remove all appropriate obstructing parts, including their fixing and
. Disconnect all mechanical and isolate all electrical linkages leading to and from the engine.
. De-gas the airconditioning system, see section 14, Charge Recovery (System depressurization).

arrangements.
CAUTION : Do not vent refrigerant directly to the atmosphere and always use Jaguar approved recovery/recycle/re- charge equipment.
. Drain the engine oil, see 3.1.3 this section.
. Drain the coolant, see SRO 26.10.01, section 4.1.
WARNING: DO NOT REMOVE THE HEADER TANK PRESSURE CAP WHILE THE ENGINE IS HOT. IF THE CAP MUST
BE REMOVED, PROTECT THE HANDS AGAINST ESCAPING STEAM AND SLOWLY TURN THE CAP ANTI- CLOCKWISE UNTILTHE EXCESS PRESSURE CAN ESCAPE. LEAVETHE CAP IN THIS POSITION UNTIL ALL
STEAM AND PRESSURE HAS ESCAPED AND THEN REMOVE THE CAP COMPLETELY.
Before lifting the complete engine/transmission unit with an engine hoist from the engine bay, ensure that two engine
lifting brackets (tool 18G. 1465) are secured equally spaced to the inlet manifold studs. The engine lifting brackets
should be positioned towards the front and the rear of the assembly. Ensure the front of the vehicle is jacked
up secure- ly on stands when removing the assembly.

SRO 12.37.01/90
The engine /transmission unit on the V12 6.0 liter model is mounted on three engine mounting / bracket assemblies
fitted to the front crossmember on either side of the engine bay. The engine/ transmission rear mount is a mounting
bracket and spring assembly fitted and secured to body underframe longitudinal members. For access to remove the
engine carry
out the following procedures:
WARNING: WHEN WORKING WITHIN THE ENGINE COMPARTMENT, KEEP CLEAR OF THE RADIATOR COOLING
FANS AS THEY COULD START WITHOUT WARNING, EVEN IF THE ENGINE IS NOT RUNNING.
. Remove the hood, see SRO 76.16.01, section 13.
. Remove the two air cleaner assemblies, see SRO’s 19.10.01 & 19.10.02.
. Remove the engine cover, see SRO 12.29.93 (V12 Engine Service Manual).
Depressurize the fuel system, see SRO 19.50.02, section 5.1.
In line with the relevant SRO’s and sections, remove all appropriate obstructing parts, including their fixing and
