timing belt for 1998-2001 KIA Sephia or Spectra to 2004

The 1998-2001 KIA Sephia or Spectra to 2004 are very similar engines and timing belt procedures.

You have to remove the driver-side front wheel to remove the crankshaft pulley bolt; so then you can remove the bottom half of the timing cover. Also, remove the headlight on that side. Then loosen the lock bolt on the power steering belt adjustment with 14mm box end. Also, the pivot bolt is accessed and removed through a slotted hole in the the power steering pulley.

The crank pulley bolt can be powered-off by bumping the starter while using a socket on a long breaker bar (with a cheater to reach the ground).

You have to remove the cover on the DOHC (dual overhead cam) to see the timing marks on the back of the cam gears, which align with the top edge of the head.

Do NOT use a wrench on the cam-gear bolt to position the cam timing mark. Instead each cam shaft has a large hex shaped lobe on it for a friend to use two wrenches to hold the position of the two marks aligned when you are ready to install the belt and tension it. But you can use a rubber cork from a wine bottle or buy a rubber stop block to put between the tops of the two cam gears to jam the gears in alignment with each other, while you put the timing belt on and tension it and lock it. Be really sure to double check that the cam mark does not move/get off line while accessing and tensioning the belt and all of that.

The tensioner pulley is NOT adjusted by prying with a lever. Instead, it is an eccentric tensioner pulley where the middle of the pulley itself is adjustable "off-center" to tension the the timing belt. So, you would loosen the center bolt and pivot the eccentric middle of the tensioner pulley when you adjust tension on the belt; when the new timing belt has been installed; then lock the tensioner by torquing the pulley bolt.

Important caution: The water pump is behind the timing cover and belt and so must be replaced at this time, as well as replacing the timing belt IDLER pulley which bolts on through the water pump and must be replaced as they can wear out at any time. If the idler or water pump were not replaced, bearings will likely dry/wear out very soon, and then you or someone would have to remove the timing belt to replace the reused idler pulley OR to replace the reused pump. (Its quite hard to see all the bolt heads holding the water pump on and/or to see which ones of the bolts, nearby, should NOT be removed).
