2004 Hyundia XG350L Timining marks confusion.
Just replaced the water pump and timing belt but have cocerns over timing marks. I have Hyunida shop manual which reflects the same as your web site for the same vehicle. Both mine and your manual show The right bank (Firewall) Left 7.3 pitch/Right 8.7 pitch and the Left bank coincidence. I have tried this shop manual method but cannot turn the crank shaft at all. Or should each sprocket be alined to a timing mark? They were not when I open the covers up.

Help please?

Did you align the timing marks before dismantling the belt & pump? This is critical as you can't rotate any shaft independently as you will bend a valve, if you feel any resistance you may be touching a valve, best to do any rotating with plugs out so you are not fighting compression, all timing marks must be aligned as in pic, I have highlighted alignment points for you to see clearly, let me know exactly what stage you are at, regarding timing point alignment.

First I was able to turn the belt and alined all timing marks prior to removing the belt. Set at TDC. During installation of the belt the (firewall) right bank rolled off the marks and you are corret I am fighting the compression. Today I will have to plug plugs and reset both banks. From what I have read about this Hyundia XG350 the right bank is a pain to keep in place during belt install. Any one out there have any tricks or tips for the reset of timing. I am tired and hot working on the ride

What I do is fit the belt over the crank, idler and out board cams and around the water pump, cut the old belt into 1" lengths you will need 4, softly clam the new belt on the 2 out side cams using the old belt sections as a cushion, now you do not have to clamp tight, just enough to hold the belt on, with these in place do the same with the inboard cams, put a spanner on the cam nut closest to the fire wall and hold tension, if I am alone, I tie it back (the spanner with tie straps) check cam alignments and if ok set tensioner, with tensioner on, check all alignment marks.

Nice idea using the old belt. I tried just to clamp the new belt onto the sprockets already with no joy there. The second I put the tensioner into place with the lock pin still installed, the fireside (right bank)sprockets continue to spring off and slip which is frustrating me. When I look at the OEM manual for this Hyundia I see the right bank may have timing marks that are offset since they give two pitch sizes. Has anyone outther done a 3.5 timing belt on a Hyundia. The manual is too vague on this install.

Simple: With crank at TDC on timing mark and confrimed #1 Cyl at its highest point. The left bank (Forward near radiator) is set to coincide sprockets with both timing marks. Just the Right bank (firewall side will not stay in time. ( I would need six sets of hands, two just to hold the sprockets in line while I install the tensioner. Help!

Just to add to this one they do sell cam sprocket holders that are made to fit between the cam gears to hold them from moving.

Trouble is the clamps are not that cheap considering they are a one of use for the home mechanic, but if you are struggling on your own, and this is a testing job, you may consider getting one and selling it on after use, no doubt others will have the same trouble.

The lisle cam holders are about 28.00 on amazon just in case you go that route.
