Steering Lock Replacement
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (23) before performing repairs or ser-
vice.
NOTE: The original radio has a coded theft protection
circuit. Be sure to get the customer's code number before- disconnecting the battery.- removing the No. 47 (7.5 A) fuse trom the under-hood
fuse/relav box.- removing the radio.
After service, reconnect power to the radio and turn it
on. When the word "CODE" is displayed. enter the cus-
tomer's 5-digit code to restore radio operation.
1. Disconnect the negative cable from the battery.
2. Remove ths dsshboard lower cover and knee bolster(s6o p8ge 23-72).
3, Disconnect the 5P connector from the under-dash
fuse/relay box and the 7P connsctor from th€ main
wire harness (see page 23-72l.,
4. Remove the steering column covars (see page
23-721.
5. Remove the column holder mounting bolts and nuts.

Lower the stee.ing column assembly.
Center-ounch each of the two shear bolts and drill

lgnition System
1. Inspect the electrodes and ceramic insulator for:
Spark Plug lnspection
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulatorDamagedgaskei
Burned or worn electrodes may be caused by:
. Advanced ignition timing. Loose spark plug
. Plug heat range too low. Insufficient cooling
Fouled plugs may be caused bY:. Retarded ignition liming. Oil in combustion chamber. Incorrect spark plug gap
. Plug heat range too high. Excessive rdling'low speed running
. Clogged air cleaner element. Deteriorated ignition coil or ignition wires
81881, 818C5 engine:
. Adjust the gap wjth a suitable gapping tool, and
replace the plug if the center electrode is rounded
as shown below.
Electrode Gap:
Standard 'l .1 ; r mm {0.043 ; ooa in)
E.

3.818C1 engine:
a Do not adjust the gap ol a platinum tip plug;
replace the spark plug it the center electrode is
rounded or if the gap is not within the specifi-
cattons.
Electrode Gap:
Standard I t.s-3., mm (0.051-3.oo4in)

Apply a small quantity ot anti-seize compound to the
plug threads belore installing the plugs.
Screw the plugs into the cylinder head tinger tight,
then torque them to 18 N.m (1 .8 kgf.m, 13lbf.ft).
