Hi Marina,

These diagrams may be a little hard to see, but the cams have a mark that align with the raised "V" on the rear timing cover and the crankshaft pulley has a notch that aligns with the mark in the 12 O'clock position on the oil pump housing.

Sounds like timing belt not on correctly. Check timing marks are aligned correctly when installing timing belt. This vehicle should have 2-3 marks to be aligned when installing belt.marks should be on cam gear/ crankshaft gear and intermediate shaft if engine is equipped with it.

Hello hjolana: My name is Roger and i will help you. I have attached a picture of the timing marks.The camshaft mark aligns with the mark at top of cover behind the cam gear. The lower mark aligns with the notch on the block and the crankshaft key way is at 12:00 o'clock. See the picture. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

Hi Rockzone, Set the the engine to Top Dead Center before removing the old belt. If you've already removed it with the timing in any other position, do the following:- Rotate the camshaft so that the drill hole through the gear, is opposite a punch match mark behind it. (The punch mark is on the front of the camshaft cap). It is advisable to use a bright light and a mirror, which you hold at an angle in front of the camshaft drive gear. Shine the light between the gear and the cylinder head. Rotate the cam until the hole aligns with the punch mark. Once aligned, then rotate the crankshaft until the 'V' cut out on the crankshaft gear aligns with the match mark arrow on the front of the oil pump housing. Make sure that the tensioner bearing is at the maximum loose setting, fit the belt. Gently release the tensioner bearing and then recheck the timing. ( Adjust if required). When correct, tighten the lock nut on the tensioner bearing. Rotate the engine, turning it with a socket spanner from the crank shaft two full revolutions, and then recheck mark alignment. When the marks align after rotation, fit back everything else. Regards Johngee10

Timing Chain and Gears REMOVAL & INSTALLATION 2.2L Engine Fig. 1: The timing marks on the sprockets should be in alignment. If not, turn the crankshaft until the marks are aligned
Fig. 2: The timing chain tensioner is retained by a Torx head bolt (1) and a regular hex head bolt (2)
Fig. 3: Unfasten the camshaft sprocket bolt
Fig. 4: Remove the camshaft sprocket and the timing chain at the same time . . .
Fig. 5: . . . then remove the tensioner assembly
Fig. 6: Compress the tensioner spring and insert a cotter pin or nail in the hole provided to hold the tensioner in position

1. Disconnect the negative battery cable.
2. Remove the front cover as previously detailed.
3. Place the No. 1 piston at TDC of the compression stroke so that the marks on the camshaft and crankshaft sprockets are in alignment (see illustration).
4. Loosen the timing chain tensioner nut as far as possible without actually removing it.
5. Remove the camshaft sprocket bolts and remove the sprocket and chain together. If the sprocket does not slide from the camshaft easily, a light blow with a soft mallet at the lower edge of the sprocket will dislodge it.
6. Using a suitable gear puller, remove the crankshaft sprocket. To install:
   
7. Press the crankshaft sprocket back onto the crankshaft.
8. Install the timing chain over the camshaft sprocket and then around the crankshaft sprocket. Make sure that the marks on the two sprockets are in alignment (see illustration). Lubricate the thrust surface with Molykote® or its equivalent.
9. Align the dowel in the camshaft with the dowel hole in the sprocket and then install the sprocket onto the camshaft. Use the mounting bolts to draw the sprocket onto the camshaft and then tighten to 66-68 ft. lbs. (91-95 Nm).
10. Lubricate the timing chain with clean engine oil. Tighten the chain tensioner.
11. Installation of the remaining components is in the reverse order of removal. Fig. 7: Exploded view of the timing chain and sprockets - 2.2L OHV engine
    

possibly you are 180 degrees off.
the timing marks are dimples on the gears to align up.
paint will be no use at all to use and have never heard of anyone using paint .
use paint on a crack balancer for the timing mark ony

1. Disconnect battery negative cable.
2. Remove power steering and air conditioning compressor drive belt by loosening power steering fasteners.
3. Remove generator bolts and generator belt.
4. Remove water pump pulley.
5. Remove crankshaft pulley and timing belt guide plate.
6. Remove upper/lower timing belt covers.
7. Turn crankshaft clockwise until "I" mark on intake camshaft pulley and "E" mark on exhaust camshaft pulley align with marks on cylinder head cover.

there is a special tool to hold gears in correct place on some of these models, but you can hold one cam at a time with a spanner then feed belt on exhaust cam then inlet cam gear
get someone to hold gears in place while you feed belt on.
the inlet cam is more prone to turn off mark more than exhaust.
if you have tensioner that needs retaining pin in when installing
you fit belt while aligning timming marks
fit tensioner as last spot to feed belt on with retaining pin in adjuster
get correct tension on belt by turning water pump so that you can flex (turn) belt 90 degrees only just while using finger and thumb
tighten water pump check flex
check all timing marks are correct
remove retaining pin from auto tensioner
turn motor over a couple of turns by hand observing tensioner arrow should hover around V mark and that all timing marks align up again(after one complete turn)

Remove number one spark plug.Rotate engine hand and cam separately until piston is at top for number one cylinder and ignition rotor is aligned at number on hole. Now you can install timing belt. Rotate engine by TWO crankshaft resolutions. Recheck timing marks. Now perform compression testve to with all spark plugs out on all cylinders. If one is low then you have an interference problem and will have to remove cylinder head to have bent valves repaired.
