When is it time to change the timing chain on a 2003 suzuki aereo

WOW you work on engines not knowing what is there?
the engines are: 7 engines.!!!
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 ill guess, ( (die roll)
2.3 L below.

all answers, USA cars, this a USA forum. so.....
ever heard of the FSM the oem factory service manual?

is the chain making noises? if yes, the guide is bad, most chains fail due to that (as a true cause)
the FSM is here , just $4 to look , so ????

the clone is Alldata.com DIY, log in and read like we do.
google alldtata.com , bingo....

now the 2.3L (just the first half, ill let you pay $4 like we do)

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).
   • 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.
   • 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.
   • 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.
     • warning
     • 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.
     • Remove timing chain guide No.1.
     • Remove timing chain tensioner adjuster No.1.
     • Remove timing chain tensioner.
     • Remove idler sprocket and first timing chain.
     • Remove crankshaft timing sprocket.
     • end.
   im not doing INSTALL, sorry.

got that? also there are a hole section on details of gasket seals and such, nothing trivial that.

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.

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.

cuantas libras de aprete lleva la culata del suzuki aereo 2006

Most manufactures recommend changing a timing belt at 100k but I've seen them go several hundred thousand miles and no problem. I've also seen them break under 100k. The best maintenance is preventative maintenance or fixing things before they become a problem. I would recommend replacing it if you have the means to do so as you will also be replacing the water pump which is driven off the timing belt (do them together)..

omg this car is pain to change timing chain it takes me 9 hour to do it with one 30 min break,if you dont have a experience changing timing chain before,do your self a favor let the pro do it.trust me.

TIMING BELT SHOULD BE 60,000 MILE CHANGE
