9) Install timing chain tensioner adjuster assembly (1) with a
retainer (2).
Tighten adjuster bolts to specified torque and then remove a
retainer from chain tensioner adjuster assembly.
Tightening torque
Timing chain tensioner adjuster bolts
(a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
10) Apply engine oil to timing chain and then turn crankshaft
clockwise by 2 revolutions and check that match marks (1)
on intake and exhaust camshaft timing sprockets are in
match with notches (2) on cylinder head and key (3) is on
upside of crankshaft as shown in figure.
If each marking chain and each match mark are no matches,
adjust each sprockets and timing chain.
11) Install timing chain cover referring to “TIMING CHAIN
COVER”.
12) Install cylinder head cover referring to “CYLINDER HEAD
COVER”.
13) Install oil pan referring to “OIL PAN AND OIL PUMP
STRAINER”.
14) Adjust water pump belt tension referring to Section 6B.
15) Adjust A/C compressor belt tension (if equipped) referring to
Section 1B.
16) Refill engine with engine oil.
17) Verify that there is no oil leakage and exhaust gas leakage at
each connection.

3) Install camshaft housing pins (1) as shown in figure.
4) Check position of camshaft housings.
Embossed marks are provided on each camshaft housing,
indicating position and direction for installation. Install hous-
ings as indicated by these marks.
5) After applying engine oil to housing bolts, tighten them tem-
porarily first. Then tighten them by the following numerical
order in figure. Tighten a little at a time and evenly among
bolts and repeat tightening sequence two or three times
before they are tightened to specified torque.
Tightening torque
Camshaft housing bolts (a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
6) Install timing chain with crankshaft sprocket referring to “TIM-
ING CHAIN AND CHAIN TENSIONER”.
7) Install timing chain cover referring to “TIMING CHAIN
COVER”.
8) Check valve lashes as previously outlined.
9) Install cylinder head cover and oil pan as previously outlined.
10) Adjust water pump belt tension referring to Section 6B.
11) Adjust A/C compressor belt tension (if equipped) referring to
Section 1B.
12) Refill engine with engine oil.
13) Verify that there is no, oil leakage and exhaust gas leakage
at each connection.
