If the timing belt broke on a 1996 Isuzu Rodeo 3.2L how do you reset the timing?
There are timing marks on the gears that MUST be aligned. An they need to line up on the Compression Stroke not the Exhaust Stroke.
You would be well advised to Consult with a Reputable Repair Shop and have them do it for you.
If you choose the DIY route the Purchase a Repair Manual

1996 Isuzu Trooper 3.2 Timing Belt Instructions.
Actually there are 3 yellow marks on your new belt:
Align top right camshaft (Drivers Side) with mark on cam gear and mark on back plate, should be straight up and to the right a little and put one yellow mark of belt on that mark:
Left Side Camshaft (Passenger Side): align cam gear with back housing which it will be off set of bottom to the left some what: and Again put one of the yellow marks from the belt on these marks.
Now the crankshaft gear has a groove with a blue mark on it: put the last yellow mark from the belt on this blue mark, blue mark will be on bottom and to left a little.
Now rotate engine 2 full turns to take out slack and then make sure the tensioner is tight: be careful not to over tighten as you will stripe out the threads.
BE SURE TO PUT THE ROTATION OF THE BELT AS IT SHOWS YOU ON THE BELT, IF YOU PUT THIS ON BACKWARDS YOU WILL NOT BE ABLE TO ALIGN THE MARKS!
Now if you have these marks of the belt on the marks with the gears it is done it will run.
I searched all over the internet for these simple instructions and could not find them so I had to do this as a touch and feel thing. I guarantee you these are correct for this year application I have been a mechanic for over 30Yrs.
