VALVES AND CYLINDER HEAD
REMOVAL
1) Relieve fuel pressure according to procedure described in Sec-
tion 6.
2) Disconnect negative cable at battery.
3) Drain cooling system.
4) Remove air cleaner outlet hose as previously outlined.

Flatness of gasketed surface:
Using a straightedge and thickness gauge, check surface at a to-
tal of 6 locations. If distortion limit, given below, is exceeded, cor-
rect gasketed surface with a surface plate and abrasive paper of
about #400 (Waterproof silicon carbide abrasive paper): place
paper on and over surface plate, and rub gasketed surface
against paper to grind off high spots. Should this fail to reduce
thickness gauge readings to within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is often
due to warped gasketed surface: such leakage results in reduced
power output.
Limit of distortion: 0.05 mm (0.002 in.)

Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds, using a
straightedge and thickness gauge, in order to determine whether
these faces should be corrected or cylinder head replaced.
Limit of distortion: 0.10 mm (0.004 in.)

A: Crankshaft pulley side
B: Flywheel side
A: Camshaft pulley side
B: CMP sensor case side

9) Install rocker arms, washers, rocker arm shaft and camshaft as
previously outlined.
10) Install CMP sensor case, intake manifold and exhaust man-
ifold.
INSTALLATION
1) Remove oil gasket and oil on mating surfaces and install new
head gasket (1) as shown in figure, that is, “TOP” mark provided
on gasket comes to crankshaft pulley side, facing up (toward cyl-
inder head side).
2) Check to make sure that oil jet (venturi plug) is installed and if
it is, that it is not clogged.
When installing it, be sure to tighten to specified torque.
Tightening Torque
(a): 3.5 N
.m (0.35 kg-m, 2.5 lb-ft)
3) Apply engine oil to cylinder head bolts and tighten them gradual-
ly as follows.
a) Tighten all bolts to 35 N
.m (3.5 kg-m, 25.0 lb-ft) according to
numerical order in figure.
b) In the same manner as in a), tighten them to 55 N
.m
(5.5 kg-m, 40.0 lb-ft).
c) Loosen all bolts until tightening torque is reduced to 0 (zero)
in reverse order of tightening.
d) In the same manner as in a), tighten them to 35 N
.m
(3.5 kg-m, 25.0 lb-ft).
e) In the same manner as in a) again, tighten them to specified
torque.
Tightening Torque
(a): 68 N
.m (6.8 kg-m, 49.5 lb-ft)

ENGINE COOLING 6B-9
WATER PUMP
1) Disconnect negative cable at battery.
2) Drain cooling system.
3) Remove timing belt and tensioner according to procedure de-
scribed in “TIMING BELT AND TENSIONER” of Section 6A or
6A1.
4) Remove water pump belt adjusting arm.
5) Remove water pump assembly (1).
INSPECTION
NOTE:
Do not disassemble water pump.
If any repair is required on pump, replace it as assembly.
Rotate water pump by hand to check for smooth operation.
If pump does not rotate smoothly or makes abnormal noise, replace
it.
INSTALLATION
1) Install new pump gasket to cylinder block.
2) Install water pump to cylinder block.
Tightening Torque
(a): 12 N
.m (1.2 kg-m, 9.0 lb-ft)
3) After installing water pump, install rubber seal (1) between water
pump and oil pump, and another between water pump and cylin-
der head.
4) Install timing belt tensioner, timing belt and timing belt outside
covers according to procedure described in “TIMING BELT AND
TENSIONER” of Section 6A or 6A1.
NOTE:
Special care must be used when installing belt tensioner
and timing belt.
Torque each bolt and nut to specification.
Before installing outside covers, check to make sure that
cover seal is fitted in groove of each cover properly.
