1994 JAGUAR XJ6 torque

A master index of numbered operations has bee? compiled for universal application to all vehicles manufactured by
Jaguar Cars Ltd.
Each operation described in this manual is allocated
a numberfromthe master indexand cross-refers with an identical
number in the Service Repair Operation Times Manual. The number consists of six digits arranged in three pairs.
Each operation is described in the sequence necessary to complete the operation in the minimum time, as specified
in the Manual of Repair Operation Times.
SERVICE TOOLS
Where non-standard service tools (i.e. tools which are not generally available hand tools) are required to complete an
operation, the number and an illustration of that tool is given in the preliminary pages of the Section concerned.
TORQUE TIGHTENING SPEClFKATlONS
Torque tightening specifications are given in tabular form in the preliminary pages of the relevant Section.
REPAIRS AND REPLACEMENTS
When service parts are required, it is essential that only genuine Jaguar / Daimler replacements are used.
Attention is drawn to the following points concerning repairs and the fitting of replacement parts and accessories:
0 Safety features embodied in the vehicle may be impaired if other than genuine parts are fitted. In certain
territories, legislation prohibits the fitting of parts which are not produced to the vehicle manufacturer's
specification.
0 Torque wrench setting figures given in this Manual must be strictly adhered to.
0 Locking devices, where specified, must be fitted. If the efficiency of a locking device is impaired during removal it must be renewed.
0 Owners purchasing accessories while travelling abroad should ensure that the accessory and its fitted location
on the vehicle conforms to mandatory requirements existing in their country of origin.
0 The vehicle warranty may be invalidated by the fitting of other than genuine Jaguar / Daimler parts. All Jaguar
/Daimler replacements have the full backing of the factory warranty.
0 Jaguar / Daimler dealers are obliged to supply only genuine service parts.
REFERENCES
References to the left or right-hand side of the vehicle are made as if viewing from the driver's seat.

3.1.3 ENGINE OIL, RENEW
SRO 12.60.00
. Undo and remove the sump plug positioned at the rear of
the sump, drain the engine oil into a suitable receptacle
and dispose of
it in a safe and environmentally friendly
manner.
Replenish the engine oil, to the correct level on the dip-
stick (see Fig. 1).
When the oil is renewed, start the engine, wait for the oil
light to extinguish and switch off the engine for 30 sec- onds.
. Finally remove and wipe clean the dip stick,
check the oil level - replenish if necessary.
. For recommended engine oil refer to Appendix AI.
3.1.4 OIL FILTER CARTRIDGE, RENEW
SRO 12.60.04
The white oil filter cartridge displaying the Jaguar logo, is lo- cated on the left-hand side of the engine below the throttle
assembly (Fig. 2).
When refitting, tighten the oil filter cartridge using hand
pressure only.
On no account use an oil filter strap designed
forthe removal
of cartridges.
m: The normal tightening torque of the oil filter is a 3/8 to 1/2 turn after initial contact.
