Answer
Replacing the timing belt on an XG is one of the more complex timing belt replacements.  If you don't have experience with replacing timing belts, I'd recommend that you either don't use this job as your on-the-job training, so to speak, or you have someone who is experienced with this type of job at your disposal for help.  Improper installation can cause severe engine damage.  I'm going to list a procedure below from memory, so be sure to verify the steps make sense while doing the job.  I also recommend that you register for a free account at www.hmaservice.com (requires Internet Explorer) and check the procedure listed in the shop manual there.  Hopefully, the combination of both procedures will assist you in doing an efficient job.

1.  Remove engine cover (six 10mm bolts).
2.  Support the right front of the vehicle with a jack stand and remove the right front wheel.
3.  Remove the right side engine splash shield.
4.  Remove the right side under engine splash shields (two 10mm bolts each).
5.  Remove the right side radiator fan (two 10mm bolts).
6.  Support the engine under the oil pan with a block of wood on a floor jack.
7.  Remove the right side engine mount.
8.  Loosen the A/C-alternator belt tensioner pulley clamping  nut (14mm).
9.  Loosen the A/C-alternator belt tensioner pulley adjusting bolt (14mm), being careful to not remove the bolt from the pulley.
10.  Remove the A/C-alternator belt.
11.  Loosen the P/S belt tensioner mounting bolt and nut (14mm).
12.  Loosen the P/S belt tensioner adjuster bolt (14mm)
13.  Remove the P/S belt.
14.  Remove the P/S belt tensioner.
15.  Remove the crankshaft pulley (one 22mm bolt).  
16.  Unplug the crankshaft and camshaft sensor connectors and remove the connectors from the holding bracket.
17.  Unbolt the power steering pressure line from the bracket on the frame rail adjacent to the rear bank upper timing belt cover (one 10mm bolt).
18.  Remove the upper timing belt covers (numerous 10mm bolts), unclipping the wiring from the cover.
19.  Remove the lower timing belt cover.
20.  Place a piece of cardboard in front of the radiator to protect it.
21.  Remove the alternator brace arm (two 12mm bolts).
22.  Loosen the alternator upper and lower mounting bolt nuts (two 14mm nuts).
23.  Unbolt the upper alternator mounting bracket from the cylinder head (two 12mm bolts).
24.  Slide the alternator out of the lower mount and move it forward into the space created by removing the radiator fan.
25.  Remove the engine mount bracket from the engine (5 14mm bolts, one if which is located behind the alternator).
26.  Rotate the engine to line up the timing marks and observe their alignment.  Some camshafts will move when the timing belt is removed.
27.  Remove the timing belt tensioner (two 12mm bolts).
28.  Remove the timing belt.
29.  Install the new timing belt around the crank sprocket, wedging something-- short 1/4" extension works well-- between the oil pump case and the belt to hold it in place.
30.  Install the belt around the front bank camshafts, keeping proper alignment, clipping or tying in place.  Leave no slack between the front camshaft and the crank pulley.
31.  Route the belt around the water pump and onto the rear bank camshafts one at a time.  You'll need to rotate the front rear bank camshaft forward a little, put the belt on, tie in place, and then rotate back to alignment to take up the slack.  The rear rear bank camshaft will turn very quickly if you move it more than a very small amount from its aligned position.  Use care and caution.
32.  If reusing the old timing belt tensioner (I recommend a new one), compress it in a shop vise and pin the piston in place using the holes in the tensioner body and piston.  A paper clip is too soft; you'll need something harder.
33.  Install the belt tensioner and remove the pin.
34.  Check the alignment marks.  If not properly aligned, return to step 28.
35.  Remove the clips/ties/wedge that you've used to hold the timing belt in place.
36.  Rotate the crankshaft two full turns.Install the engine mount bracket.
37.  Check the alignment marks.  If not properly aligned, return to step 28.
38.  Install the timing belt covers, clipping the sensor wiring back in place.
39.  Reinstall the alternator and brace.
40.  Reinstall the power steering belt tensioner pulley, leaving the mounting bolt and nut loose.
41.  Install the power steering belt and tension.  
42.  Tighten the power steering belt tensioner pulley mounting bolt and nut.
43.  Install the A/C-alternator belt and tension.
44.  Tighten the A/C-alternator belt tensioner pulley clamping nut.
45.  Reinstall the engine mount.
46.  Reconnect the connectors and clip in place.
47.  Bolt the power steering line onto the bracket.
48.  Reinstall the radiator fan.
49.  Reinstall the three engine plastic covers/splash shields.
50.  Reinstall the right front wheel.
51.  Lower the vehicle.
52.  Reinstall the engine cover.
