Timing belt and diesel pump timing for hyundai h100 2.6 diesel
The timing belt broke some teeth, i would like to replace the belt myself as i am retired and cannot afford the cost to repair. Can someone please let me know how to go about the replacement of the belt and the setting up of all the pulleys including the injector pump.
I am most appreciative for the help.

The 2002 Santa Fe 4 cyl and 6 cyl engines are deemed "Interference" engines. If the timing belt should break or slip a few teeth, the pistons will strike the valves and most likely destroy the engine. Thus it is very important to change the timing belt every 80,000 - 100,000 miles (along with a replacement water pump). I recommend buying a belt/pump kit and having a local independent shop do the install (much cheaper than a dealer's $600 charge!).
Starting in 207 Hyundai started shifting all of their engines to metal timing "chains"... more or less eliminating the possibility of such a problem. However, water pumps still go out... but not nearly as often or catastrophic a problem!
Remove all necessary components for access to the timing belt cover, then remove the cover.
Rotate the crankshaft clockwise and align the timing marks so No.1 piston will be at Top Dead Center (TDC) of the compression stroke.
Loosen the tensioning bolt and the pivot bolt on the timing belttensioner. Move the tensioner as far as it will go toward the waterpump. Tighten the adjusting bolt.
Mark the timing belt with an arrow showing direction of rotation if belt is to be reused.
Remove the timing belt.
If defective, remove the timing belt tensioner.

Align the timing marks of the camshaft sprocket and check that the crankshaft timing marks are still in alignment.
If removed, install the timing belt tensioner, spring and spacer with the bottom end of the spring free. Tighten the adjusting bolts lightly with the tensioner moved as far as possible away from the water pump.
Install the free end of the spring into the locating tang on the front case.
Position the timing belt over the crankshaft sprocket, then over the camshaft sprocket. Slip the back of the belt over the tensioner wheel.
Turn the camshaft sprocket in the opposite of its normal direction of rotation until the straight side of the belt is tight and be sure the timing marks align. NOTE If the timing marks are not properly aligned, shift the belt 1tooth at a time in the appropriate direction until they are aligned.
Loosen the tensioner mounting bolts so the tensioner works,without the interference of any friction, under spring pressure. Be sure the belt follows the curve of the camshaft pulley so the teeth are engaged all the way around. Correct the path of the belt, if necessary.
Tighten the tensioner adjusting bolt, then the tensioner pivot bolt to 15-18 ft. lbs. (20-26 Nm). NOTE Bolts must be tightened in the stated order or tension won't be correct.
Turn the crankshaft 1 turn clockwise until timing marks again align to seat the belt.
Loosen both tensioner attaching bolts and let the tensioner position itself under spring tension. Retighten the bolts.
Check belt tension by putting a finger on the water pump side ofthe tensioner wheel and pull the belt toward the water pump. The belt should move toward the pump until the teeth are approximately 1 / 2 of the way across the head of the tensioner adjusting bolt. Re-tension the belt, if necessary.
Install the timing belt covers and all other related components.
The 2.4l and 2.5l engines are interference engines, meaning it is highly likely that you bent your valves when your timing belt broke. Besides the timing belt, you may need a new belt tensioner and pulleys. I would replace the water pump too.
Yes, you are just about spot on for the timing belt. Leave the water pump - if it ain't broke don't fix it. Changing the belts does not disturb the water pump so wait until it actually starts to leak, and that could be in years to come.
this car has no chain! It has a toothed rubber belt for timing belt. It could have broken or the crankshaft toothed pulley (behind the harmonic balancer or main accessory belts pulley) has either broke off teeth or shaved off the timing belt teeth but it still should move under tension. Remove the top black plastic timing belt cover( 2 each 8mm screws or may have Phillips + center). You can see if the belt is on tight or even if it will turn when you try to start. Have someone turn it over while you observe the belt. That is my problem but I haven't gone to the process of taking it all apart yet. Not a fun job and it's expensive! Not only that but since you are replacing the belt one way or the other, there are kits for this engine with new pulleys, belt etc...) Consider replacing water pump if its old or you will be doing the same thing soon to replace the pump! Might as well do it now!
