Geo metro 1998 crankshaft pulley.

The crankshaft pulley bolt loosens by turning Counter-Clockwise. Ensure the pulley is secure from movement so that you can loosen the pulley bolt without turning over the engine. You may need to use breaker bar to loosen the pulley bolt, or at least a large wrench.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

need to use a pully puller yes there are bolt behind the cover hope this helps you

im not familliar with the car but it looks to be a front wheel drive so my sugestion would be to remove the front wheel strut ect it is the easiest way that i have found to access pulleys and timing belts on frontwd's some cars also require you to remove the top engine mount and lower the engine with a jack hope this helps but as i said im not familliar with the car

roll the crankshaft pulley around until u get the mark to line up with 0 or TDC. once u get the cover off mark the cam sproket to the head with whiteout and mark the crank gear to the block also. (in case they move on you. loosen tensioner and pry to one side.tighten tensioner bolt and remove the belt. install new belt and get the slack to move toward the tensioner side. (u may have to move the cam slightly to allow all the slack to go toward the tensioner. then move it back to the mark, making sure the crank didnt move. loosen tensioner bolt and let it spring toward the belt and apply pressure with yr hand a little more snug while u tightn bolt. then rotate the crankshaft 2 revolutions by hand and your marks should line back up. if the marks are more than 1/2 tooth off u must re do it!

the small bolts on the outer ring and the big bolt in the center, if the timing gear has to come off a puller will be needed

1993–96 2.3L and 2.6L Engines

1. Disconnect the negative battery cable.
2. Loosen and remove the engine accessory drive belts.
3. Remove the cooling fan assembly and the water pump pulley.
4. Drain the fluid from the power steering reservoir.
5. Unbolt and remove the power steering pump. Unbolt the hydraulic line brackets from the upper timing cover and move the pump out of the work area without disconnecting the hydraulic lines.
6. Disconnect and remove the starter motor if a flywheel holder (part No. J–38674) is to be used.
7. Remove the upper timing belt cover.
8. Rotate the crankshaft to set the engine at TDC/compression for the No. 1 cylinder. The arrow mark on camshaft sprocket aligns with mark on the rear timing cover.
9. Remove the crankshaft pulley.
10. Remove the lower timing belt cover.
11. Verify that the engine is set at TDC/compression for the No. 1 cylinder. The notch on the crankshaft sprocket aligns with the pointer on the oil seal retainer.
12. Release and remove the tensioner spring to release the timing belt's tension.
13. Remove the timing belt.
14. Unbolt the tensioner pulley bracket from the engine's front cover.
15. If necessary, unbolt and remove the camshaft sprockets. Use a puller to remove the crankshaft pulley if necessary. Don't loose the crankshaft sprocket key. To install:
    
16. Install the camshaft and crankshaft sprockets if they were removed. Align the timing marks and be sure to install any keys. Tighten the camshaft sprocket bolt to 43 ft. lbs. (59 Nm).
17. Install the tensioner assembly. Tighten the tensioner mounting bolt to 14 ft. lbs. (19 Nm). Tighten the cap bolt to 9 ft. lbs. (13 Nm).
18. Make sure the crankshaft and the camshaft sprockets are aligned with their timing marks. Install the timing belt onto the sprockets using the following sequence: first, crankshaft sprocket; second, oil pump sprocket; third, camshaft sprocket.
19. Loosen the tensioner mounting bolt. This will allow the tensioner spring to apply pressure to the timing belt.
20. After the spring has pulled the timing belt as far as possible, temporarily tighten the tensioner mounting bolt to 14 ft. lbs. (19 Nm). NOTE: Remove the flywheel holder before rotating the crankshaft. Reinstall the holder to torque the crankshaft pulley bolt.
    
21. Rotate the crankshaft counterclockwise two complete revolutions to check the rotation of the belt and the alignment of the timing marks. Listen for any rubbing noises which may mean the belt is binding.
22. Loosen the tensioner pulley bolt to allow the spring to adjust the correct tension. Then, retighten the tensioner pulley bolt to 14 ft. lbs (19 Nm).
23. Install the lower timing cover and the crankshaft pulley.
24. Tighten the crankshaft pulley bolt to 87 ft. lbs. (118 Nm). Tighten the small pulley bolts to 6 ft. lbs. (8 Nm).
25. Install the upper timing cover.
26. Install the starter if it was removed. Tighten the bolts to 30 ft. lbs. (40 Nm).
27. Install the power steering pump. If the hydraulic lines were disconnected, refill and bleed the power steering system.
28. Install the water pump pulley and tighten its nut to 20 ft. lbs. (26 Nm).
29. Install the cooling fan assembly.
30. Install and adjust the accessory drive belts.
31. Connect the negative battery cable.

yes it does have to come off, you will have to undo the motor mount on that side of the engine and lower the engine a little. use a jack with a board under the enging to lift and lower as needed.

1. Remove the negative battery cable.
2. Drain the engine cooling system.
3. Remove the air cleaner assembly.
4. Remove the A/C compressor suction pipe bracket (if equipped).
5. Loosen four water pump pulley bolts. Do not remove the bolts.
6. Raise the vehicle. Support the vehicle. Remove the right lower splash shield.
7. Remove the right lower splash shield.
8. Remove the A/C compressor drive belt (if so equipped) by releasing the tensioner pulley and removing the belt from the crankshaft and compressor pulleys.
9. Loosen the generator adjusting bolt (1), pivot the generator and remove the water pump/generator drive belt.
10. Remove the crankshaft pulley.
11. Remove the water pump pulley (four bolts).
12. Remove the timing belt.
13. Remove the oil level indicator (dipstick) guide tube.
14. Remove the upper generator adjusting bracket from the water pump (one bolt).
    
    
    1. Remove the rubber seals from the water pump.
    2. Remove the water pump mounting bolts and nuts.
    3. Remove the water pump and gasket from the vehicle.
    4. Clean the water pump and the gasket mating surfaces.
    5. Install the water pump.
    6. Secure the water pump with mounting nuts and bolts. Tighten Tighten the water pump mounting nuts and bolts to 13 Nm (115 ft. lbs.).
    7. Install new rubber seals (1) to the water pump (2).
    8. Install the upper generator adjusting bracket to the water pump (one bolt).
    • Tighten the upper generator mounting bracket bolt to 23 Nm (17 ft. lbs.).
    1. Install the oil level indicator (dipstick) guide tube.
    2. Install the timing belt.
    3. Install the water pump pulley.
    4. Finger-tighten the four bolts.
    5. Install the crankshaft pulley.
    6. Install the water pump/generator drive belt to the crankshaft, water pump and generator pulleys.

As long as they are the same type of engine ( I believe they should both be 1.0L 3 cyl engines). Most parts for the Geo Metro from 1992 to 1994 interchange with out a problem.

Put a jack under the engine. Loosen the upper engine mount bolts and lower the engine until you have enough clearance.
