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.

Installation
Installthe cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cylinder block surface must be
ctean.
. "UP" mark on the timing belt pulleys should be at the
top.
. Do not use the middle cover and lower cover for stor-
ing items disassembled.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated.'1. Cylinder head dowel pins and the oil control orifice
must be aligned,
NOTE:
. When handling a metal gasket, care should be
taken not to told it or damage the contact surface
of the gasket.
. Clean the oil control orifice when installing.

Tighten the cylinder head bolts in two steps. In the
Jirst step tighten all bolts, in sequence, to about 29
N.m {3.0 kgf.m, 22 lbl.ltJ; in the final step, tighten in
the same sequence to 83 N.m (8.5 kgf.m, 61 lbf'ft).
NOTE:
. Apply engine oil to the cylinder head bolts and
the washers.
. Use the longer bolts at positions No. 1 and No. 2
as shown.

NOTE: lf camshaft-to-holder oil clearances (see page 6-
21) are not within specitication, the head cannot be
resurfaced.
lf camshaft'to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurtacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in), resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.
