There are timing marks on the cams and crank sprocket, the cams marks must align and the crank mark will be at the beginning of the tooth that aligns the sprocket. Although this is a non interference motor, you should install the new belt tensioner, idler, and water pump, remove spark plugs, and do a compression check on each cylinder before you start putting any other parts on or covers. Replace cam seals if they are leaking.
Line up the marks on crank shaft gear arrow to arrow, the front cam gear the mark goes to the middle on the rear cam gear the mark goes one notch below front gear mark they line up when the tension is put on belt.

You need to purchase a Haynes Manual or better. They are very common in your nearest chain part store. Like Autozone, Advance, Napa. More than likely you will have to set the crankshaft at TDC. "top dead center" and allign the two marks with the cam shaft! Watch when you put tension on the belt it will move the camshaft sprocket! And throw it back out of time.
It is possible to set the timing wrong....if the belt broke well running I believe this is an interference motor..meaning if the timing is off the cylinder can move up and smack a Valve being exhaust or intake. which means a valve can break or bend cause lack of seal thus no compression. When setting the timing you want to align your marks with Cylinder # 1 it needs to be on the compression stroke..you can do this by removing cyl 1 spark plug and rotating the crankshaft with your finger over the spark plug hole you will feel air press against your finger meaning all valves are closed and your in compression stroke. Then line up your marks and you should have it...I would consider purchasing a compression tester to make sure no damage to the cylinder head....good luck hope this helps
Only the 2.3 liter diesel is an interference engine. The 2.3 Liter gas is not an interference engine. I would guess the belt was not installed correctly. The belt broke so the cam was then out of alignment with the crankshaft. Unless you aligned it correctly it will not start. BTW, the belt must be replaced every 60,000 miles.
I asume you have the timing cover off, put it back on and set the crankshaft at the 0 mark on the timing cover, remove the cover and don't touch the crank. near the bottom of the cam gear is a protruding piece of plastic with three raised areas, set the cam timing mark at the first pointer, closest to the passenger side . on the back part of the timing cover is a v shaped pointer set the distributor gear mark at the pointer, remove the distributor cap and verify that the rotor is pointing at #1. Loosen both bolts on the tensioner and using a pry bar carefully pry the tensioner away from the distributor gear, tighten the small bolt on the tensioner. install the new belt starting at the crank, then the distributor gear, then the cam, then over the tensioner pulley. loosen the small bolt and the tensioner will adjust automatically. tighten the tensioner bolts and turn the engine over by hand 2 or 3 times and make sure all marks line up ( the cam mark should now be at the center pointer with the crank at 0). I find it handy to paint a reference mark for the crank inside the timing cover.
you have to line up the two marks on the gears and set the tension to the correct setting. then check the marks again. trial and error. i just did my timing belt on my ranger haha
hi from uk as you do not mention engine litres ? on average it takes approx 2 hours to change belt and tensioner on 1.8=2;0=cv v t 16 valve engines fitted with air con ? simple enough to diy with instructions and timing mark set up b4 you begin dismantle hope this helps ?
hi from uk the cambelt timing marks you req are as follows the crank cog has a dot indent on it and it has to align with same mark on the engine front at approx 12-30 pm position? it is clearly visible then the cam cog you will see a small drilled hole on the cog between the outer toothed and the centre securing bolt ? this hole in cog has to be positioned at top 12 o'clock position then look through this hole and you will see it lines up with a V indent on cyl head this too is clearly visible and advise setting this up b4 fitting c/head for ease ? with these marks set up the engine is at T D C number 1 firing just a note! if you arefitting new belt? it is advisable to replace the tensioner too ! as a kit here in uk belt+tensioner costs £50 if you wish? i can scan and e mail full instructions on cambelt+tensioner strip+renewal proceedure plus detailed diagram of belt set up and relevent marks and tensioner proceedure if you send an e mail address best wishes from n/west uk
TIMMING BELT MARKS
NEED MORE INFO ON ENGINE 4 CYL OR 6 CYL
ALSO IF YOU JUST REPLACED THE HEAD ASSEMBLY MEANS YOU BENT THE VALVES WHEN THE BELT BROKE. TIMMING MARKS ARE DIFFERANT ON MANY MAKES PURCHASE A CHILTON MANUAL FOR THE YEAR AND MAKE OF YOUR CAR THESE MANUALS ARE GREAT AND TAKE THE GUESS WORK OUT OF THE TIMMIMG MARK ISSUE
If the timing belt broke, he should take it to have it replaced because theres more than likely to be bent valves in the head. Heads should be checked before putting another timeing belt on. If there is valve damage, then more than likely there damage to the pistons too.
