I replaced the head, am confused about timeing marks. Some say line up with marks on timing cover some say line marks on gears towards each other. also haveing to install gears the intake one is easy with only one key way. but exhaust has 2 key ways on back???

The timing belt diagrams are listed in detail with figures and procedure to remove them.

REPLACING TIMING BELT ON A 2003 HYUNDAI TIBURON 2.7L V6

1. Remove passenger side headlight via the 3 10mm screws holding it in place and disconnect the turn signal and main harness

2. Remove passenger side tire

3. Remove the splash guard via 2 10mm screws at the top of the guard

4. Remove the 2 17mm bolts and 2 17mm nuts from motor mount bar

5. You may have to separate the mount bar from the motor via either a chisel or flathead screwdriver and a hammer ( support engine via a jack and a piece of plywood under oil pan )

6. Use a 3/8 ratchet ( or a long breaker bar would work better ) to remove the serpentine belt ( remember the route ). Disconnect the power steering hose from the pump and secure back with a zip tie. Remove the power steering pulley with a pry bar and 19mm socket.


7. Hand turn the crankshaft via a 22mm socket to TDC ( top dead center, marked on lower timing belt cover )

8. Remove the serpentine belt tensioner via 2 12mm bolts on each side

9. Remove the upper timing belt cover via 7 10mm screws

10. Remove crankshaft pulley ( 22mm ) with an air impact gun ( an electric one will work too )

11. Remove lower timing belt cover via 4 more 10mm screws





12. Remove the motor mount from the block via 3 14mm bolts and 2 12mm bolts ( there is a 12mm holding the oil dipstick bracket towards the front of the car )

13. Remove the auto tensioner via 2 12mm bolts



14. Remove the timing belt


15. Make sure your timing markings are correct...

There is one marking on each cam gear and on the heads ( head markings are small, look closely...try wiping the edge of the head down with a rag and some brake cleaner to bring it out more ) They are also pictured in last pic.

When the crankshaft is in the TDC position, the cam gear markings should both line up at the same time with the head markings

Adjust if necessary, use a 17mm socket to turn cam gears to correct position

16. Install new timing belt ( as you install it, make sure to keep a little tension on the belt as you route it )

17. Install new auto tensioner and pull pin

18. Install just the lower timing belt cover

19. Install the crankshaft pulley

20. Hand turn the crankshaft atleast 5 times to verify the timing markings are lining up properly ( all should line up at the same time when the crankshaft pulley mark is in the TDC position )

21. Remove crankshaft pulley

22. Remove lower timing belt cover

23. Reverse steps 12 - 1

How to time engine --Turn crankshaft to t.d.c. turn camshaft so valves on number four cylinder start to open and close ( rock back and forth )line up marks on cover and cam gear .key way will line up ,may have to move cam just a bit.

Remove the serpentine belt, remove the lower crankshaft pulley, place a jack under the oil pan and jack up the engine slightly, remove the engine mount (right top). Remove the timing belt cover, loosen the timing belt tensioner and pull tensioner pulley back toward the rear of vehicle. I like to then tighten the tensioner bolt to hold it in this position, remove and replace belt. If you need to put the engine in time then look at the camshaft there is a small arrow in the center, it lines up with a dot on the end of the cylinder head. The lower timing mark is a small metal tip that sticks out from the lower gear, and it lines up with a notch cut into the front cover just behind the lower gear. Once aligned properly put the belt on the lower gear and without turning the lower gear or camshaft gear pull the belt tight up to the cam shaft the cogs in the belt will line up with the grooves, then place the belt around the water pump drive gear and under the tensioner, then push the belt over all gears by hand without turning the engine. Loosen the tensioner bolt and apply a little pressure toward the front of the vehicle and tighten the bolt. Replace everything else previously removed. Engine should start and run normally.

their is timing marks where they suppose to line up stamped into the engine block cam gears and on the head. twin cams u points marks on cam gears straight toward mark on other cam gear

Install the cam sprocket, timing chain, and timing chain cover. Make sure the dot on the crankshaft gear is pointing towards the center of the Camshaft gear bolt. Make sure the hole in the Camshaft gear is pointing towards the center of the crankshaft. Be sure to remove the nail holding the chain tensoner back, before installing the timing cover The round hole in the cam gear is the alignment mark

roll the crankshaft pulley around until u get the mark to line up with 0 or TDC. once u get the cover off mark the cam sproket to the head with whiteout and mark the crank gear to the block also. (in case they move on you. loosen tensioner and pry to one side.tighten tensioner bolt and remove the belt. install new belt and get the slack to move toward the tensioner side. (u may have to move the cam slightly to allow all the slack to go toward the tensioner. then move it back to the mark, making sure the crank didnt move. loosen tensioner bolt and let it spring toward the belt and apply pressure with yr hand a little more snug while u tightn bolt. then rotate the crankshaft 2 revolutions by hand and your marks should line back up. if the marks are more than 1/2 tooth off u must re do it!

Hope this helps, let me know.

put the number one cylinder at top dead center and line up the timing marks on the cam gear and put the belt on
