I need the steps to disassembly this machine to replace the engine chain.

you can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

there is a lot to completing this job, your best bet is to look it up on youtube, that will show you step by step. Good Luck it would take a lot of explaining on here.

The engine does not have a chain. If the belt broke or came off for some reason the engine will need to be disassembled and all the bent valves replaced.

wow no engine stated of the many.
1.3 L I4; 1.5 L I4; 1.6 L I4; 1.8 L I4; 2.0 L I4; 2.3 L I4; 1.4 L Diesel I4 amazing huh, no engine or COUNTRY stated.
my answer will be USA< as this is a USA forum
and like all cars in USA the engine list it smaller (EPA rule and Bs)
ever seen and FSM book, factory service manual
for any car made, ?
2nd best is always.... here. log in an read?

real FSMs. here (official suz. site)
or at suzukipitstop (google it)

no my GUESS,(useless if outside USA totally, mostly)

2.0 or 2.3L: working on engines, not knowing what is there???
here is the teaser answer, no photos , no warnings, etc.

quoted in part, and remove chain only.
exploded view of first timing chain and related components-2.0L and 2.3L engines

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove engine assembly from vehicle.
3. Remove oil pan.
4. Remove cylinder head cover.
5. Remove timing chain cover as follows:
   • Remove crankshaft pulley bolt. To lock crankshaft pulley, use special tool 09917-68221 (camshaft pulley holder).

Be sure to use the following bolts instead of pins for fixing special tool to crankshaft pulley. Bolt size: M8, P1.25 L = 25 mm (0.98 in.) Strength: 7T

• Remove crankshaft pulley. To remove crankshaft pulley, use special tools 09944-36011 and 09926-58010 (steering wheel remover and bearing puller attachment).
• Remove A/C compressor bracket.
• Remove alternator belt idler pulley, water pump pulley and alternator belt tensioner.
• Remove timing chain cover bolts and nut.

1. For reinstallation of timing chain, turn crankshaft so that timing marks on cylinder head and lower crankcase match with those on sprockets as shown in figure.
2. Remove second timing chain as follows:
   • Turn crankshaft to meet following conditions.
     • Key (I) on crankshaft is positioned as shown.
     • Arrow mark on idler sprocket (II) points upward.
     • Marks on sprockets (III) match with marks on cylinder head. Note that this step must be followed for reinstallation of timing chain.
   • Remove timing chain tensioner adjuster No.2 and gasket. To remove them, slacken second timing chain by turning intake camshaft counterclockwise a little while pushing back pad.
   • Remove intake and exhaust camshaft timing sprocket bolts. To remove them, fit a spanner to hexagonal part at the center of camshaft to hold it stationary.
   • Remove camshaft timing sprockets and second timing chain.

After second timing chain is removed, never turn intake camshaft, exhaust camshaft and crankshaft independently more than such an extent as shown. If turned, interference may occur between piston and valves and valves themselves, and parts related to piston and valves may be damaged.

1. Remove timing chain guide No.1.
2. Remove timing chain tensioner adjuster No.1.
3. Remove timing chain tensioner.
4. Remove idler sprocket and first timing chain.
5. Remove crankshaft timing sprocket.

end teaser.

its a long process for the novice. I suggest getting a repair manual at your local autoparts store to help in your troubles. The process includes finding the timing marks, partial disassembly of engine to access timing belt/chain. To sum up the process, you disconnect your battery, remove timing chain cover, line up timing mards on camshaft/crankshaft which could be dots, marks or grooves, replacing the belt/chain, and reassembling engine. The repair manual will give step by step instructions as well as pictures. To post all that here would take more than 10,000 charecters of text, which fixya limits us to 10,000 charecters. Very long detailed list of procedures for sure!

If the chain is rattling and the engine still runs, the chain is not broke, but you may have a damaged tensioner that keeps it tight.
The timing parts are behind the timing cover on the passenger side of the engine, behind the water pump.
if you decide to tackle the job, get a repair book and read up on it first to see if you are up to the task.

Hi,

you will be needing the following for this operation:

1. Combination Wrenches
2. A Socket Set
3. Torque Wrench
4. A Harmonic Balancer Puller
5. A Three-jaw Gear Puller
6. Screwdrivers
7. Hammer and Punch
8. Gasket Scraper
9. Timing Light
10. Tube of Silicone Sealer
11. Timing Chain Cover Gasket Set
12. New Timing Chain and Gears
13. Drain Pan
14. Antifreeze
15. Jack
16. Jack stands

Before You Start:

• Follow these instructions carefully. Read and be sure you understand them before you begin.
• Gather together all of your tools and supplies before you begin.
• Allow plenty of time to do the job so you don't have to hurry.
• Remember that these are general instructions. For more detailed instructions pertaining to your specific vehicle, consult an appropriate repair manual.
• Safety is important whenever you're working around machinery. Beware of hot objects, sharp instruments and hazardous materials.
• Don't substitute tools unless you're sure you won't compromise either your safety or the performance of your vehicle.
• Never work on a vehicle that is only supported by a jack. Use jack stands to support the vehicle while you work. Work on a solid, level surface. Never jack a car up on dirt or grass.

Why Replace Your Timing Chain? Over time, wear on internal working parts of your engine will spell the need for replacement. One of the internal working parts that wear is the timing chain and timing sprockets. The timing chain and sprockets are the connecting line between the crankshaft and the camshaft. As the crankshaft turns, via the timing chain, it drives the camshaft that operates the engine's valves via the lifters, push rods and rocker arm assemblies The timing of the valves opening and closing at precise intervals is crucial for proper engine operation. As the timing chain and sprockets wear, this precise timing of the valves gradually changes, eventually to a point where replacement is necessary.
Telltale signs of worn out timing chains are:

Rough idle.

Sluggish performance and poor economy.

Sudden engine performance change including the inability to start the engine.

Intermittent backfire through the intake manifold.

Inconsistent ignition timing or a clattering noise coming from the front of the engine. Before starting the disassembly procedures, I would suggest cleaning the engine with an engine degreaser. A clean engine is easier to work on and helps prevent dirt or contamination from entering the engine during disassembly.

Call for a mechanic help if the task is too much for you.

Best regards.

should be able to get the cover off with the engine in the frame. Just take out the grille and header support, then disassemble the front of the engine. If you are dead set on removing the engine, she comes out the front after taking everything out of the way.

I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time. 

Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".

If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.

Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common. 
These chains are not generally expensive but replacing them can involve a fair amount of work. 

Good Luck and hope this helps, Others will have different ideas.
