I have a 2002 grand vitara 2l petrol .it has done 67k . when should i change the timing belt

Possibly a bad connection on the Cam Sensor. Clean the two sides of the plug with electrical switch cleaner.

2.5L engine? v6.
you broke it , didnt you.
the 2.5L has no belt so its not 2.5L , 2.5L is CHAIN,(i own one same year)
must be a 4 cylinder engine??
and G16>
world wide GV have these engines
1.6 L G16B I4 (petrol)
2.0 L J20A I4 (petrol)
2.5 L H25A V6 (petrol)
2.0 L RF/RFM I4 (diesel)
2.0 L RHW/RHZ I4 (diesel)

only the 1.6BL gas has a belt.
lucky for you its not an INTERFERENCE engine or boom.
I also have A G16 suzuki and know how to time it.
the G16, must be cam timed at #4 cylinder firing, never #1
this is stated in the gates belt page, the FSM and alldata.com
and here.

after changing the belt , i always check that i have my 170psi
compression back (wideopen throttle) or its all just a waste of time.

its not the CKP unplugged, as this engine runs with out one.
fact.
here are all G16b steps.
and nice photos. and the false marks, that is correct, suzuki
gawd love em. uses the cogs on 2 engines. 3cyl and 4cyl.

all pitfalls are here. every one.

what engine, there are many. what country ,same.
some have a chain. no belt.
the belt change is complex,
login to alldata , its all there. or mitchells.
or go to pub. lib and see esources , under car repair
free factory service manuals there on that screen there.
i can log in to my lib and see them now. can you?
you need only library card...

the warning light with the padlock on shows that your car immobilizer is active. Need a specialist to re program your immobilizer.

their are no signs taht you can see ,i normally say 80/90 th kms in a dry hot climate and 20,000kms more in a cooler damper climate .The belts tend to dry out quicker in a dry climate ,if you remove the covers and see cracking at the base of the teeth of the belt then is the time to start to think about changing it ,cracking on the outside is not a major problem as this can appear on a belt after a small amount of use as i have seen this after a couple of weeks of changing a belt myself

best bet go to mitchell or chilton on demand, otherwise buy a manual, any free diagrams will not be complete and you don't want to have to do it twice

I'd be first confirming whether you have a 1.6 litre Grand Vitara (petrol), or a 2 litre turbo diesel. The 2 litre petrol (straight 4 or V6) or 2.5 litre petrol engines are all chain drive.
If your engine is petrol then no lock tool is required (to hold the camshaft). Of course, there is a specific position that an engine should be rotated too before removing the belt from ANY engine.
If it's diesel, then although I'm unfamilar with that particular engine, the general requirement for diesel engines with high pressure injection pumps is "yes, you require a lock tool" to hold the injection pump pulley. As I think these are a common rail set-up, this requirement may not be necessary. Check with your Suzuki Dealer, or maybe someone else here will know more. A similar question may have already been asked and answered here too.

The belt is loose. This is one of the first signs for the belt change.

If it has a belt - it should be changes every 60-k to 80-k miles..

Have a great day !

Inside the housing that the BOTTOM hose goes onto. I assume you have a 2L 4 cyl or 2.5L V6 petrol version. I don't know about the TDi (if available).
