TIMING CHAIN/GUIDES/SPROCKETS (Continued)
(3) Install camshaft sprocket bolt. While holding
the camshaft sprocket with Special Tool 8435, torque
bolt to 115 N·m (85 ft. lbs.) (Fig. 114).
(4) Reset the timing chain tensioner using the fol-
lowing method:
(a) Remove oil reservoir cap from timing chain
tensioner (Fig. 122).
(b) Place tensioner on a clean flat surface.
(c) Place your palm against the tensioner and
press down on the tensioner with continuous pres-
sure until the fully extended tensioner bottoms out
(Fig. 123).
(d) Install oil reservoir cap onto timing chain
tensioner (Fig. 122).
(5) Install timing chain tensioner with oil reservoir
cap into engine block (Fig. 115).
(6) Install timing chain tensioner plug with seal
ring. Torque plug to 62 N·m (46 ft. lbs.).
CAUTION: Do not pry directly on chain. Damage to
timing chain may occur.
(7) Using a long thin screwdriver, pry in on the
right (movable) timing chain guide until the timing
chain tensioner rachets out to tension the chain (Fig.
120).
NOTE: Ensure the timing chain is properly posi-
tioned within the channel of the timing chain

guides.

(8) Install cylinder head cover (Refer to 9 -
ENGINE/CYLINDER
COVER(S) - INSTALLATION).
(9) Install camshaft position sensor. Torque fas-
tener to 10 N·m (85 in. lbs.). Reconnect connector.
(10) Connect negative battery cable.
INSTALLATION - TIMING CHAIN AND GUIDES
(1) Install the left timing chain guide. Torque fas-
tener to 28 N·m ( 250 in. lbs.) (Fig. 116).
(2) Install the right timing chain guide. Torque
fastener to 28 N·m ( 250 in. lbs.) (Fig. 116).
NOTE: When installing the timing chain, ensure the
plated links on the timing chain are aligned with the
timing marks on the crankshaft and camshaft
sprockets. If a timing chain is being re-used, and
the plating is wore off the chain, the links also have
machined dimples (Fig. 121).
(3) Feed the timing chain through the opening in
the top of the cylinder head.
(4) Install the timing chain around the crankshaft
sprocket, aligning the two plated links with the
crankshaft sprocket timing marks (Fig. 121).

(5) Install the timing chain around the camshaft
sprocket, aligning the single plated link with the
camshaft sprocket timing mark (Fig. 121).
(6) Install the camshaft sprocket on the camshaft.
CAUTION: DO NOT use an impact wrench (or any
other air operated tool) for tightening the camshaft
sprocket bolt. Damage to the camshaft timing pin
can result. ONLY use a hand wrench while holding
camshaft sprocket with Special Tool.
(7) Install camshaft sprocket bolt. While holding
the camshaft sprocket with Special Tool 8435, torque
bolt to 115 N·m (85 ft. lbs.) (Fig. 114).
(8) Reset the timing chain tensioner using the fol-
lowing method:
(a) Remove oil reservoir cap from timing chain
tensioner (Fig. 122).
(b) Place tensioner on a clean flat surface.
(c) Place your palm against the tensioner and
press down on the tensioner with continuous pres-
sure until the fully extended tensioner bottoms out
(Fig. 123).
