the number of teeth is irrelevant
a replacement for the engine will either fit or it is the wrong belt
you go by the position of timing marks on the pulleys against marks on the head and on other pulleys
if you are replacing a timing belt then a workshop manual would be a very good investment.
it is an intereference engine so moving either cams or crank with out a belt in position will cause bent valves
If you are trying to bypass the compressor for the air conditioner then you need to ensure two things.
1. That there is some way to tension that belt if the compressor is bypassed.
2. you will need to find a shorter belt that has the same physical profile. Wrap a string around the pulleys that remain and measure the length. A shop should then be able to give you a belt that will fit. Take the old belt with you to ensure it has the right profile.
1. Ensure locking bolts located correctly [4] & [5] in the picture below: CS = Crankshaft CA = Camshaft IP = Injection Pump
2. Ensure timing marks aligned [10]. 3. Fit timing belt in clockwise direction, starting at crankshaft sprocket.
NOTE: "ISUZU" lettering on belt should be readable from front of engine.
4. Slacken tensioner pulley bolt [9]. Push tensioner pulley against belt. 5. Ensure belt is taut between injection pump sprocket and tensioner pulley as well as crankshaft sprocket and camshaft sprocket. 6. Position tensioner lever [8] against tensioner pulley housing. 7. Remove locking bolts from sprockets [4] & [5]. 8. Apply a load of 10 ... 12 kg to tensioner lever. Use spring balance [11]. 9. Tighten tensioner pulley bolt to 80 Nm. 10. Turn crankshaft slowly 45 degrees anti-clockwise. Use spring balance to tension belt. 11. Repeat tensioning procedure at 45 degrees intervals for one anti-clockwise turn of the crankshaft.
NOTE: DO NOT turn crankshaft clockwise during tensioning procedure!
12. Fit tensioner lever to original position. Tighten nuts [12]. 13. Install: Injection Pump flange [6], Camshaft sprocket flange [7], and water pump pulley. 14. Install components in reverse order of removal & refill coolant. Hope that helps. and good luck out there in the country side.

I would suggest getting a Chilton book or something comprable for your year make and model.. That has all that type of info and how to diagrams.. A great investment..
These can be found at moost auto part stores..
You need a 14mm socket on a extended breaker bar,
place on automatic tensioner center pulley bolt which is the dumpy pulley located above the alternator.
Move the nut to tighten which will move spring loaded tensioner to low side which will allow you to slip belt off.....installlation is the reverse
~KS
Crank the tensioner over so that you have some slack in the belt and pull the old one from one easily accessible pulley. Pull the belt off the pulley system and put the new one on following the diagram. Crank the tensioner again and use a screwdriver to pull the belt over the uppermost pulley. Release the tensioner and check belt tension.
The engine will fit but the accessory's. Just make sure you have the same engine which is the L36. if you can get a L26 which would be the years 2005 to 2008 from a Buick LaCrosse, that would be a better investment since it has the aluminum upper intake and stronger connecting rods which is the only physical changes to the engine. The compression ratio is still the same at 9.4:1 but with the stronger rods, you can put a simple 6 pounds of boost out of a turbo and get another 90 HP with an inter cooler, looking at 285 HP with a 330 pounds of torque running on 91 octane. God luck and hope this helps, here is link http://cartuning.ca/about/
