I need to know how to set the timing belt on my 2003 cadillac cts 3.2L.engine.any diagrams will help a lot thanks

Timing Belt & Sprockets

Apply tension to the timing belt, at the upper idler pulley by turning the high point of the eccentric to approximately the 9 o'clock position the idler pulley locking bolt, while holding the eccentric with the J 42069-40 or other suitable tool, until snug.

Setting the initial timing belt tension



Rotate the tensioner eccentric counter clockwise to full stop, turn the eccentric back until the reference mark is 1 mm (0.03 inch) over the flange.
Tighten the timing belt tensioner locking nut until snug.

Marks on timing belt



Inspect the alignment marks on the timing belt to ensure that they are aligned with the appropriate reference points on the camshaft gears, the rear timing belt cover and on the oil pump housing.

Remove tools



Remove the J 42069-30 or other suitable tool, the J 42069-1 and the J 42069-2 or other suitable locking tools from the engine.

Rotate the crankshaft clockwise 2 revolutions using the J 42098 or other suitable tool until the # 1 cylinder is 60 degrees BTDC.

Using the J 42069-10 or other suitable tool



Install the J 42069-10 or other suitable tool to the crankshaft sprocket with the knurled bolt.
Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098 until the lever of the J 42069-10 or other suitable tool firmly contacts the water pump pulley flange.
Secure the moveable lever of the tool to the water pump pulley flange. NOTE: The alignment marks on the timing belt will no longer align with the marks on the camshaft gears after one or more engine revolutions.


Timing marks aligned



Inspect the alignment of the reference marks on the camshaft gears with the notches on the rear timing belt cover, as well as the mark on the crankshaft sprocket and oil pump housing. NOTE: The reference marks on both sets of the camshaft gears must match exactly with the marks on the J 42069-20 or other suitable tool checking gage.


Inspect timing gear alignment with J42069-20 or other suitable tool



Use the J 42069-20 to inspect the alignment of the camshaft gears 3 and 4.
Use the J 42069-20 to inspect the alignment of the camshaft gears 1 and 2.

Timing belt final tension



Loosen the timing belt eccentric locking nut.
Turn the eccentric counter clockwise to full stop, then back to the following specification:
NEW BELT - until the reference mark is 3 - 4 mm (0.11 - 0.157 inch) (1) above the datum line.
USED BELT - until the reference mark is aligned with the datum line.
Tighten the timing belt tensioner eccentric locking nut
Torque to 15 ft. lbs. (20 Nm)

Tighten the upper idler pulley bolt



Hold the upper idler pulley eccentric in place with the J 42069-40 or other suitable tool
Torque to 30 ft. lbs. (40 Nm)
Remove the J 42069-20 or other suitable tool from the camshaft gears.
Remove the J 42069-10 or other suitable tool from the engine.
For final inspection::
Rotate the crankshaft in the engine rotational direction, clockwise 2 revolutions using the J 42098 or other suitable tool until reaching 60 degrees BTDC.
Install the J 42069-10 or other suitable tool to the crankshaft sprocket.
Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098 until the lever of the J 42069-10 or other suitable tool firmly contacts the water pump pulley flange.
Secure the moveable lever of the tool to the water pump pulley flange.
Inspect the alignment of the reference marks on the camshaft gears with the notches on the rear timing belt cover, as well as the mark on the crankshaft sprocket and oil pump housing.
Use the J 42069-20 or other suitable tool to inspect the alignment of the camshaft gears 3 and 4.
Use the J 42069-20 or other suitable tool to inspect the alignment of the camshaft gears 1 and 2.
If the reference marks on the camshaft gears do not match exactly, timing belt adjustment IS REQUIRED.
If the reference marks match exactly, further timing belt adjustment IS NOT necessary. Continue with reassembly of the engine.
Remove the J 42069-10 and the J 42069-20 or other suitable tools.
Install or connect the following:
Crankshaft damper
Timing belt cover
Test drive the vehicle to confirm repairs.
