I can get you a diagram on monday but it goes from the alternator to the power steering pump then around the tensioner pulley then around the crank pulley then to the a/c compressor then pull on the tensioner to give you some slack and slip it on the waterpump.I hope that helps.Let me know if you still need the diagram

Get a T belt from toyota. It has 3 white lines on
it and and arrow mark. 2 lines are solid and one is broken. Put the
arrow facing away from the engine. The cam gears have a dot punched
into them near a certain tooth. This is where the solid white lines
will line up with. The crank gear will have a dot also. It will line up
at 90 degrees from the top, towards the front of the car. This is where
the broken line will match up with. With the belt installed with all
lines on their proper dots and arrow away from the engine, you valve
timming is correct.
Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.

malibluert: YOUR IN LUCK! This series engine is simple and the references aren't hard to find. READY???????
IF you are just trying to reset the belt at the top and have not remover the crank pulley, bring the crank around to Top dead center on the # 1 cylinder,. It will read Zero degrees on the timing mark scale.
Up top, look at the cam gear closely You will see that there are 5 spokes which support the actual gear. Look closer and you will see that one of these spokes has a small hole in it about 3/4th of the way towards the outside of the gear. Position the gear to where that hole is at 12:00 PM. NOW, if you look thorough the hole, you should should see a small notch that the hole should be centered on. If not, move the gear until you can look through the hole and the notch falls dead center. At that point in time, you have the crank ant camshaft in perfect time with each other.
When you put the belt on, make sure that the side which is slack is the tensioner side. You should be able to slip the belt on, matching the teeth with the teeth on the gears to where one side is fairly tight and you can not roll the cam counter clockwise.
IF you are replacing the belt, you have the crank pulley off and you position the woodruff key straight up at 12:00 PM and the procedures are all the same other than that. when you set the tension. A good rule of thumb is to find the longest span of belt, and with your thumb and forefinger twist the belt. if it twists to 45 degrees toward the block, it's perfect. Any more or less, needs to be reset.
I hope my answer suffices. A picture wouldn't be any more clear.
Let me know how you did.
NOTE: This engine does NOT bend valves when a timing belt fails.
