TIMING VERIFICATION
Remove the outer timing covers. Rotate the crank-
shaft until the pointer on the crankshaft sprocket
aligns the TDC mark on the oil pump. Check to
determine if the camshaft sprocket timing marks are
aligned with the marks on the inner timing cover. It
may take an additional full revolution of the crank-
shaft before the camshaft sprocket marks are aligned
(Fig. 150).
CAUTION: The 3.5L is NOT a freewheeling engine.
Therefore, loosen the valve train rocker assemblies
before servicing the timing drive.
(1) Perform fuel pressure release procedure. (Refer
to 14 - FUEL SYSTEM/FUEL DELIVERY - STAN-
DARD PROCEDURE).
(2) Disconnect negative battery cable.
(3) Remove both cylinder head covers and loosen
the rocker arm assemblies.
(4) Remove the front timing belt cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
(5) Mark belt running direction, if timing belt is to
be reused.
CAUTION: When aligning timing marks, always
rotate engine by turning the crankshaft. Failure to
do so will result in valve and/or piston damage.
(6) Rotate engine clockwise until crankshaft mark
aligns with the TDC mark on oil pump housing and
the camshaft sprocket timing marks are aligned with
the marks on the rear cover (Fig. 150)
(7) Remove the timing belt tensioner (Fig. 150)
and remove timing belt.
(8) Inspect the tensioner for fluid leakage.
(9) Inspect the pivot and bolt for free movement,
bearing grease leakage, and smooth rotation. If not
rotating freely, replace the arm and pulley assembly.
