I do not know which engine you have so here are 2 diagrams.

For 2.4, there is an additional balancer belt which has to be timed correctly.

I put a new timing belt and related parts in my 2004 sonata 2.4l motor, it starts but has a fludder sound with no power. I could not remove plug on side of motor. So I could not check the balance shaft position, however I did not remove the sprocket. Does this still have to be done.

You should ensure that balance shaft timing is correct and re check valve timing, was the belt changed for what reason, if it failed or you turned the engine with the belt off, you will have bent valves as it is an interferance engine.

Dealer recommends replacing timing belt becuase of transmission damange if belt breaks. Is this a manufacture problem/defect.

Hi there,

You will not damage the transmission, but you will have valve damage in the cylinder head. This is a standard replacement item which should be replaced when the manufacture recommends, there Will be no warranty claim on damage if a belt brakes so I would recommend that you have it changed if it is due.
