(g) Remove the LH No.3 timing belt cover.
(h) Remove the bolt, nut and oil cooler pipe.
11. REMOVE NO.2 TIMING BELT COVER
Remove the 2 bolts and No.2 timing belt cover.
12. DISCONNECT A/C COMPRESSOR FROM ENGINE
(See page EM±79)
13. REMOVE FAN BRACKET
Remove the 2 bolts, 2 nuts and fan bracket.
14. IF RE±USING TIMING BELT, CHECK INSTALLATION
MARKS ON TIMING BELT
Check that there are 3 installation marks on the timing belt by
turning the crankshaft pulley as shown in the illustration.
HINT:
If the installation marks have disappeared, place a new installa-
tion mark on the timing belt before removing each part.
15. LOOSEN CRANKSHAFT PULLEY BOLT
Using SST, loosen the pulley bolt.

16. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the timing marks of the camshaft timing pul-
leys and timing belt rear plates are aligned.
If not, turn the crankshaft 1 revolution (360°).
(c) Turn the crankshaft pulley approx. 50° clockwise, and
align the timing mark of the crankshaft pulley with the cen-
ters of the crankshaft pulley bolt and the No.2 timing belt
idler pulley bolt.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulley (step 15), causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(d) Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.
17. REMOVE TIMING BELT TENSIONER
HINT:

When re±using the timing belt:
If the installation marks have disappeared, before remove
the timing belt, place 2 new installation marks on the tim-
ing belt to match the timing marks of the camshaft timing
pulleys.

When replacing the timing belt tensioner only:
To avoid meshing of the timing pulley and timing belt, se-
cure one of them with string. And place matchmarks on
the timing belt and RH camshaft timing pulley.
Alternately loosen the 2 bolts, and remove them, the belt ten-
sioner and dust boot.
18. DISCONNECT TIMING BELT FROM CAMSHAFT TIM-
ING PULLEYS
(a) Hold the camshaft timing pulley with SST, and loosen the
tension spring between the LH and RH camshaft timing
pulleys by slightly turning the LH camshaft timing pulley
clockwise.

HINT:
Set the SST so that the claw comes in contact with the camshaft
timing pulley bolt, and tighten the lock nut of the SST.
(b) Disconnect the timing belt from the camshaft timing pul-
leys.
19. REMOVE CAMSHAFT TIMING PULLEYS
(a) Hold the camshaft timing pulley with SST, loosen the 4
bolts of the timing pulley.
SST 09960±10010 (09962±01000, 09963±01000)
(b) Remove the 2 timing pulleys.
20. REMOVE GENERATOR (See page CH±7)
21. REMOVE DRIVE BELT TENSIONER
Remove the bolt, 2 nuts and belt tensioner.
