(6) Lower the primary chain with left side sprocket
through the left cylinder head opening.
NOTE: The camshaft sprockets can be allowed to
float on the camshaft hub during installation.
(7) Loosely position left side camshaft sprocket
over camshaft hub.
(8) Align timing (plated) link to the crankshaft
sprocket timing mark (Fig. 120).
(9) Position primary chain onto water pump drive
sprocket.
(10) Align right camshaft sprocket timing mark to
the timing (plated) link on the timing chain (Fig.
120) and loosely position over camshaft hub.
(11) Verify that all chain timing (plated) links are
properly aligned to the timing marks on all sprockets
(Fig. 120).
(12) Install left side lower chain guide and ten-
sioner arm (Fig. 118). Tighten attaching bolts to 28
N·m (250 in. lbs.).
NOTE: Inspect O-ring on chain guide access plugs
before installing. Replace O-ring as necessary.
(13) Install chain guide access plugs to cylinder
heads (Fig. 118). Tighten plugs to 20 N·m (15 ft. lbs.).
NOTE: To reset the primary timing chain tensioner,
engine oil will first need to be purged from the ten-
sioner (Fig. 121).
(14) Purge oil from timing chain tensioner using
the following procedure:
(a) Place the check ball end of tensioner into the
shallow end of Special Tool 8186 (Fig. 121).
(b) Using hand pressure, slowly depress ten-
sioner until oil is purged from tensioner (Fig. 121).
(15) Reset timing chain tensioner using the follow-
ing procedure:
(a) Position cylinder plunger into the deeper end
of Special Tool 8186 (Fig. 122).
(b) Apply a downward force until tensioner is
reset (Fig. 122).
NOTE: If oil was not first purged from the tensioner,
use slight finger pressure to assist the center arm
pin of Special Tool 8186 to unseat the tensioner's
check ball.
CAUTION: Ensure the tensioner is properly reset.
The tensioner body must bottom against the top
edge of Special Tool 8186. Failure to properly per-
form the resetting procedure may cause tensioner
jamming.
(16) Install the reset chain tensioner into the right
cylinder head (Fig. 117).
(17) Position tensioner retaining plate and tighten
bolts to 12 N·m (105 in. lbs.) (Fig. 117).
(18) Starting at the right cylinder bank, first posi-
tion the camshaft damper (if equipped) on camshaft
hub, then insert a 3/8" square drive extension with a
breaker bar into intake camshaft drive hub. Rotate
camshaft until the camshaft hub aligns to the cam-
shaft sprocket and damper attaching holes. Install
the sprocket attaching bolts and tighten to 28 N·m
(250 in. lbs.) (Fig. 118).
(19) Turn the left side camshaft by inserting a 3/8"
square drive extension with a breaker bar into intake
camshaft drive hub and rotate camshaft until the
sprocket attaching bolts can be installed. Tighten
sprocket bolts to 28 N·m (250 in. lbs.) (Fig. 118).
(20) Rotate engine slightly clockwise to remove
timing chain slack, if necessary.
(21) Activate the timing chain tensioner by using a
flat bladed pry tool to gently pry tensioner arm
towards the tensioner slightly (Fig. 123). Then
release the tensioner arm. Verify the tensioner is
activated (extends).
(22) Install power steering pump and bracket
assembly.
(23) Install camshaft position sensor and connect
electrical connector.
