the cap. Clean and check the cap as
described in Chapter 1.
2 If the cap is to be renewed, record the
position of the HT leads in relation to the cap,
then pull them off. Transfer the leads to a new
cap, refitting them in the same position.
3 To remove the rotor arm, withdraw the
plastic shield (where fitted), then undo the
retaining grub screw using an Allen key (see
illustrations). Withdraw the rotor arm
from the end of the camshaft or distributor
shaft.
Refitting
4 Refitting the rotor arm, shield and
distributor cap is a reversal of removal. Ensure
that all traces of thread locking compound are
removed from the rotor arm retaining grub
screw and its threaded hole, then apply fresh
thread locking compound, such as
Loctite 222 or equivalent prior to refitting.
Failure to remove all traces of old compound
first, may cause seizure of the grub screw,
making subsequent removal impossible.
6 Distributor (V6 engines) -
removal and refitting
3
2.5 litre engines
Removal
1 Disconnect the battery negative (earth) lead
(refer to Section 1 before doing this).
2 Using an open-ended spanner, undo the
two retaining screws and lift off the distributor
cap. Recover the large O-ring seal from the
base of the cap.
3 Release the wiring multiplug and, where
applicable, the EGR valve vacuum hose from
the distributor support clips.
4 Mark the position of the vacuum hose
connections at the distributor vacuum unit
and disconnect the hoses.
5 Disconnect the distributor multiplug from
the ignition coil and the lead from the radio
condenser then release the wiring from the
cable clips.
6 Prise off the plastic cap from the bolt
securing the distributor to the cylinder head.
7 Using a small punch or fine file, mark the
position of the distributor base relative to the
cylinder head.
8 Undo the distributor retaining bolt and
withdraw the unit from the cylinder head.
Recover the O-ring at the base of the
distributor body.
Refitting
9 With the distributor located on the cylinder
head, turn the rotor arm until the offset drive
dog positively engages with the slot in the end
of the camshaft, then push the distributor
body fully home. Once in place, align the
distributor body with the mark made on
removal. The remainder of refitting is a
reversal of removal. After installation, adjust
the ignition timing as described in Section 10.
2.7 litre engines
Removal
10 Disconnect the battery negative (earth)
lead (refer to Section 1 before doing this).
11 Using an open-ended spanner, undo the
two retaining screws and lift off the distributor
cap. Recover the large O-ring seal from the
base of the cap.
12 Release the wiring multiplug and the EGR
valve vacuum hoses from the distributor
support clips.
13 Disconnect the distributor multiplug from
the connector on the side of the distributor.
14 Undo the support clip bolt and release the
harness from the side of the distributor body
(see illustration).
15 Undo the distributor retaining bolt and
withdraw the unit from the cylinder head (see
illustrations). Recover the O-ring at the base
of the distributor body.
Refitting
16 With the distributor located on the
cylinder head, turn the rotor arm until the
offset drive dog positively engages with the
slot in the end of the camshaft, then push the
distributor body fully home. The remainder of
refitting is a reversal of removal.
7 Ignition coil -
testing, removal and refitting
2
Testing
1 The ignition coil is mounted on the left-hand
side of the engine compartment, on the
suspension strut tower.
2 Testing of the coil is carried out using an
ohmmeter, or multi-meter set to its resistance
function, to check the primary and secondary
coil windings for continuity. Ensure that the
ignition is switched off before carrying out the
following checks.
3 On 4-cylinder engines disconnect the LT
and HT wiring at the coil, and connect an
ohmmeter across the positive and negative LT
