How to change a timing belt on a hyundai Elantra 1.5 , 1.6 and 2.0 engine

A timing belt replacement is a very complex job but can be done and here is how.
first locate the belt, it should be behind a cover on the front of your engine (behind all the other belts)
second and most importantly DON'T CRANK THE ENGINE!!!! ( if you already have cranked it or you suspect the camshaft or crank shaft has moved then you will need to find top dead center or TDC I will explain this a little later).

step 1
jack the car up and support with jack stands (for transverse mounted FWD engines remove the passenger wheel and access cover)

step 2
remove serpentine belt and any accessory items in the way (I.E. power steering pump, A/C.) and remove the timing belt cover

step 3
remove timing belt tensioner, and idler pulleys as well as the belt itself.

step 4
align crankshaft and cam shaft. removal of crankshaft pulley may be necessary. remove #1 spark plug and plug hole with finger , have assistant rotate crankshaft until pressure is felt on finger. once you find this align the arrows on the crankshaft pulley and engine block.
for the camshaft pulley just rotate it to align with the arrow on the head.

step 5
install new tensioner ( if new tensioner comes equipped with a pin to hold it in the "no tension " position leave it in) and idler pulleys it is always recommended but not always needed to replace all timing belt components. Install new belt and release tensioner pin.

step 6
rotate engine manually 2 full revolutions and ensure that timing marks are still aligned. install #1 spark plug and re-assemble front of engine

Start and pray! Like I said, timing belt replacement is very important to get right. if you got something wrong you will know it immediately.

hope this helps! good luck!

The timing belt can be inspected by removing the upper (front outer) timing cover.

1. Disconnect the negative battery cable.
2. Remove the accessory drive belts.
3. Remove the timing belt covers.
4. Identify the timing belt running direction to avoid reversal during installation.
5. Loosen timing belt tensioner bolt and remove timing belt.
6. Remove the crankshaft sprocket flange.

To install:

1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
8. Install the crankshaft sprocket flange.
9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
11. Install the timing covers.
12. Install the accessory drive belts.
13. Connect battery negative cable.

REMOVAL & INSTALLATION

See Figures 1, 2 and 3

1. Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

1. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
5. Remove the timing belt.

To install:

1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.

1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
2. Install the crankshaft pulley and belt guide.
3. Install the timing belt cover.
4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
5. Position the alternator and drive belts, then adjust and tighten it to specifications.
6. Start the engine and check the ignition timing. Adjust the timing, if necessary.

The IGNITION timing on your Ranger is computer-controlled and is not adjustable.


Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.

1. Remove the access plug.
2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.
