2000 hunandi accent need timemarks for top side found mark on gear but cant find anything toline it to on head.where is the upper mark for head

The timing marks allow the engine to be correctly timed . It depends on what you are trying to do . If you are just trying to time the engine with a timing light .Then the mark that you would look for would be on the harmonic balancer thats the lower pully that that fits over the front of the crank shaft there will be a corasponding mark on the vehicle next to the pully that has marks in degrees that you can line up with the pulley as it turns and you use a timing light attached to #1 cylinder and ground to see this alignment the light flashes as the engine turns and lights the point up at the correct time to see it . Then you adjust the disturbutor to control where the mark moves so you can make the alignment move by turning the shaft . If you are talking about timing marks on the timing chain gears then there is a dot on each gear upper and lower and they need to be aligned in the middle so the lower gear the dot or mark is at the top of the gear and the upper or cam gear is faceing down but this alignment needs to be a perfect alignment if its off by 1 tooth you will know it the vehicle will not run vary good and back fire a lot

There is a fuse for the headlight. Maybe marked head lamp.

Flats of all four cams on the ends opposite gears need to be parallel to top of head where cam cover bolts on. Dark links on transmission side of cam gears should line up with pins at 12:00 positions on cams. Dark links on pulley side of gears should line up with marks on intake gears. Dark link on balancer shaft gear lines up with tooth at 5:00 position. Dark link on crankshaft gear lines up at 4:00 position.

Here is a diagram of the pulley side marks.



Here is what the marks look like on the tranmission side of the gears on the front head:

there are timing marks on the sprockets. the upper siprocket should have the dowel pin in the 12 oclock position then you will see a mark on the right side of the sprocket at about the 3 oclock position that you can align with a small arrow on the head. the lower sprocket also has timing marks indicating top dead center. Be careful because the 1.5 is what you call an interference motor which means if the belt actually broke the valve will get hit by the pistons cause them to be bent and ruined. you will have to remove the head and replace the valves.

Timing belt removed, static timing was not set before removing timing belt.

[Set Static Timing:
No.1 piston is brought up to TDC before removing timing belt.

Cam gear has a punchmark on face of gear, and this mark aligns with one single tooth. There is a matching punchmark on the Timing Belt Rear Upper Cover.

Facing the cam gear, the mark is to the upper right. There is an 'egg shape' of the timing belt upper rear cover, in this spot. This punchmark is in that 'egg shape', and is close to a bolt hole. The cam gear mark lines up with the Timing Belt Rear Upper Cover, mark.

The crankshaft gear has a punchmark on the face. It lines up with one single tooth. There is a corresponding punchmark on the lower right side. An alignment mark)

Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)

Barring you cannot find the crankshaft mark, find the camshaft alignment marks, make sure they are aligned with the alignment, (Punchmark), on the Timing Upper Rear Cover.

Count the teeth in the timing belt. There should be 133 teeth on the belt.

There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.

(43 teeth in-between the Right Side Camshaft mark to crankshaft mark, 43 teeth in-between the Left Side Camshaft mark to crankshaft mark)

There should be 40 teeth in-between the two cam gears.

there are no marks on the gears you must remove the valve cover, on the rear of the cams there is a flat side. With crankshaft on #1 use a straight edge between the cams to align

14. Remove timing belt.
CAUTION:
1. Do not bend or twist the belt, otherwise its core
could be damaged. The belt should not be bent at
a radius less than 30 mm.
2. Do not allow oil or other chemical substances to
come in contact with the belt. They will shorten
the life.
3. Do not attempt to pry or stretch the belt with a
screw driver or any other tool during installation.
4. Store timing belt in a cool and dark place. Never
expose the belt direct sunlight or heat.

yes those are the marks and it sounds like its not in timing
