Engine removal is not required for this procedure.
CAUTION: To avoid damaging tho cylinder head, wait
until tho ongino coolant temporature drops bolow 100"F
{38"C) beforo loo36ning the rotainin0 bolts.
NOTE:
. Inspect the timing belt before removing the cylinder
neao.
. Turn the crankshaft pulley so that the No. 1 piston is
at top dead center (TDCI (page 6-12).
. Mark all emissions hoses before disconnecting them.. Anti-theft radios have a coded theft protection circuit.
Be sure to get the customer's code number before.- Disconnecting the battery.- Removing the No. 32 (7.5 A) fuse irom the under-
hood fuse/relay box.- Removing the radio.
After service, reconnect oower 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 terminalfrom the battery.
2. Drain the engine coolant (see page 10-5).
. Remove the radiator cap to speed draining.
3. Relieve fuel pressure (see Section 1 1).
@ Do not smoke whils working on tusl
systom, keep opon flame or spark away trom work
area. Drain fuol only inlo an approvod containsr.
4. Disconnect the fuel feed hose.
