Engine Performance problem
2005 Hyundai Accent 4 cyl Two Wheel Drive Automatic 59,000 miles
I want to replace timing belt and water pump. For you that have done it on this model, is it a job for the shop or can I do it? I'm really concerned about the limited space there is and also getting the pulley off. Looks like an impact wrench will be a really tight fit. Thanks.
Lift vehicle using a jack. Remove engine support bracket, if necessary. Loosen, but do not remove water pump pulley bolts. Remove all accessory drive belts. Remove pulleys from crankshaft and water pump.
CAUTION:DO NOT rotate engine counterclockwise. If reusing timing belt, place reference mark on timing belt to indicate direction of rotation before removal.
Remove timing belt covers and gaskets, noting bolt length and location. Rotate crankshaft clockwise to align timing marks on crankshaft and camshaft sprockets. See Fig. 1 .
If reusing old belt, place mark on belt to indicate direction of belt rotation. Loosen timing belt tensioner bolts, and move tensioner inward toward water pump. Temporarily tighten bolt in slotted side of tensioner. Remove timing belt.

Check timing belt for cracks, cracked or missing teeth, and separating canvas. Inspect timing belt tensioner and idler pulley for worn bearing.
Ensure camshaft and crankshaft timing marks are still aligned. See Fig. 1 . Move timing belt tensioner toward water pump and tighten bolt. Install crankshaft sprocket (if removed) with chamfer (flange) toward engine.
Install timing belt on crankshaft sprocket, timing belt idler, camshaft sprocket and timing belt tensioner. Make sure there is no slack in belt. If reusing old belt, ensure belt is installed in original direction of rotation.
Apply counterclockwise force on camshaft sprocket to apply tension on tension side of belt. Ensure all timing marks are aligned. See Fig. 1 .
CAUTION:Slot-side timing belt tensioner bolt must be tightened before pivot-side to prevent belt tensioner from rotating, causing belt to be overtightened.
Loosen timing belt tensioner bolts to place tension on timing belt. Tighten timing belt tensioner bolts to specification. See TORQUE SPECIFICATIONS .
Smoothly rotate crankshaft clockwise for 2 full revolutions. Realign crankshaft and camshaft timing marks. To check belt tension, hold belt tensioner and timing belt together and apply slight thumb pressure (about 11 lbs.) at center point of belt tensioner.
Ensure belt cog will reach half the width of timing belt tensioner bolt on slot-side of belt tensioner. Install crankshaft flange. Install timing belt cover. To install remaining components, reverse removal procedure. Adjust drive belts to proper tension.

This can be a tricky repair if you have never attempted it before ! .. you can usually get a impact gun on crankshaft sprocket if you remove the road wheel and backing cover
Hope this helps

Big help! Thanks. I would like to ask 1 more question. I have a repair cd for this model, but doesn't show the location of number 1 spark plug cylinder. How can I tell which one it is? Thanks one more time! You have been very helpful!

#1 is always the cylinder closest to the timing/cam belt ..
Hope this helps .. please let us know how your repair goes and any tips you may have for other forum user's !
