Removal & Installation2.2L Engine
-
Before servicing the vehicle, refer to the Precautions Section.
-
Drain the cooling system.
-
Drain the engine oil.
-
Remove or disconnect the following:
NOTE
The timing chain has 2 matching colored links and 1 uniquely colored link.
Negative battery cable,
PCV hose,
Fuel line bracket,
Ignition coil and module assembly
Ground strap from camshaft cover,
Camshaft cover,
Front fender liner,
Accessory drive belt
Crankshaft balancer pulley,
Accessory drive belt tensioner,
Front cover-to-water pump bolt
Remaining front cover bolts,
Front cover
-
Rotate the engine until the crankshaft sprocket mark aligns with the matching colored link (2) at the 5 o-clock position.
-
Confirm that the INT diamond on the intake camshaft sprocket is
aligned with the uniquely colored link at (1) the 2 o-clock position.
-
Confirm that the EXH triangle on the exhaust camshaft sprocket is aligned with the matching colored link (3).
-
Remove or disconnect the following:
NOTE
Use a 24 mm wrench to hold the camshafts to prevent them from turning.
Timing chain tensioner,
Fixed timing chain guide access plug,
Fixed timing chain guide
Upper timing chain guide, Exhaust camshaft sprocket, Timing chain tensioner guide
Intake camshaft sprocket,
Timing chain through the top of the cylinder head
Crankshaft sprocket

To install:
-
Install the crankshaft sprocket with the timing mark in the 5 o-clock position.
-
Assemble the intake camshaft sprocket to the timing chain with the
timing mark lined up with the uniquely colored link (1). Hand tighten a
new intake camshaft sprocket bolt.
-
Lower the timing chain through the opening in the cylinder head.
-
Route the timing chain around the crankshaft sprocket and line up
the first marching colored link (2) with the timing mark on the
crankshaft sprocket.
-
Install the exhaust camshaft sprocket with a new bolt loosely onto the exhaust camshaft.
-
Align the timing mark on the sprocket with the last matching colored (3).
-
If necessary, align the camshaft as follows:
-
Using a 24 mm wrench, first turn the intake camshaft until the
alignment feature on the back of the camshaft sprocket seats in the
notch in the front of the intake camshaft.
-
Turn the crankshaft 45 degrees in either direction.
-
Turn the intake camshaft to the appropriate location.
-
Turn the crankshaft back to top dead center (TDC).
-
When the sprocket seats in on the camshaft, tighten the sprocket bolt hand tight.
-
Verify all of the colored links and the appropriate timing marks are still aligned.
-
Install the fixed timing chain guide. Tighten the bolts to 133 inch lbs. (15 Nm).
-
Install the upper timing chain guide. Tighten the bolts to 89 inch lbs. (10 Nm).
-
Using a 24 mm wrench to hold the camshafts, tighten the camshaft sprocket bolts 63 ft. lbs. (85 Nm) plus 30 degrees.
-
Measure the timing chain tensioner from end to end. A new
tensioner should be supplied in the fully compressed non-active state. A
tensioner in the compressed state will measure 2.83 inches (72 mm)
front end to end. A tensioner in the active state will measure 3.35
inches (85 mm) from end to end.
-
If the timing chain tensioner is not in the compressed state, perform the following steps:
-
Remove the piston assembly from the body of the timing chain tensioner by pulling it out.
-
Install the bottom half of the Tensioner tool J-45027-2 into a vise.
-
Install the notch end of the piston assembly into the bottom half of the tensioner tool.
-
Using the top half of the Tensioner tool J-45027-1, turn the ratchet cylinder into the piston.
-
Install the compressed piston assembly back into the timing chain
tensioner body until it stops at the bottom of the bore. Do not compress
the piston assembly against the bottom of the bore.
-
Install the timing chain tensioner assembly. Tighten to 66 ft. lbs. (75 Nm).
-
Release the timing chain tensioner by compressing it approximately
0.08 inches (2mm). Feed a rubber-tipped tool down through the cam drive
chest to reset on the cam chain. Give the tool a sharp jolt diagonally
downwards to release the tensioner.
-
Install the timing chain oiling nozzle.
-
Install the timing chain guide bolt access hold plug with silicone
sealant on the threads. Tighten the plug to 59 ft. lbs. (90 Nm).
-
Install or connect the following:
Camshaft cover. Tighten the bolts to 89 inch lbs. (10 Nm).
Front cover with new gasket. Tighten the bolts to 18 ft. lbs. (25 Nm).
Accessory drive belt tensioner. Tighten the bolts to 33 ft. lbs. (45 Nm).
Crankshaft balancer pulley using a new bolt. Tighten the bolt to 74 ft. lbs. (100 Nm) plus 75 degrees.
Accessory drive belt,
Front fender liner,
Ground strap to camshaft cover
Ignition coil and module assembly,
Fuel line bracket,
Air intake assembly,
Negative battery cable
-
Refill the cooling system to the correct level.
-
Refill the engine with oil to the correct level.
