I just recently experienced the same problem. The timing is 180 degrees out. Unfortunately the only way to correct it is to take the engine apart again. Set the right hand camshaft to TDC by using the marks on the timing gear for that bank. The left will follow to the degree it can although you will have to manually hold the cam in position when you put the timing gear back on. Now you can remove the timing chain. The crank TDC indicator may not be right on but it will be close. Rotate the crank CW one revolution to the point the TDC marks are lined up. Now install the timing chain according to the instructions. The timing gears on the camshafts will only go on one way as the bolt holes are slightly off the extreme diameter of the gear. If you put the chain back on making sure that all the marks are proper, she'll fire on the second cylinder up. Not a fun job I know, but when everything works right, you do get a sense of satisfaction.
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
You can refer the videos below for further assistance.Your valuable feedback would be appreciated.Thanks for choosing Fixya.
timing belt set set wrong firing to early.this a classic case of timing gone wrong.even one notch out will result in a badly running engine.bring it back and get it retimed on the belt/chain.adrian
You need timimg marks, There are the internal marks for installing timing chain, you follow the marks on the crank and cam and line them up, for the Ignition timing you follow the marks on the crankshaft harmonic balance, and the marks on the timimg chain cover for top dead center ect..
Slack in the timing chain. Some of these car came with a fibergear set instead of a metal gear set. You will have to pull the water, then the timimg chain cover. You wil have to replace the top & bottom gear on the motor, plus the new chain. This usually will come in a set. You will also need a time gear cover set, gasket kit.There are 2-marks to line up on these two gears to set your time with, (timing marks).
