Can you give me the engine timming belt instalation procedures for an Isuzu 6vd1 dual overhead CAM engine?

I had to replace the water pump and the timming seems to be a bit off. It idles rough and has less power. I found your related article on an Isuzu trooper but I could not read the diagrams in the article. We live in Ecuador as missionaries and I am trying to make this repair myself.

Only found some info on an izuzu motor. Make sure your timing marks are exactly on time.

Did the old one break? If it did, get a compression test to verify no bent valves/

Timing belt Install the timing belt in the sequence indicated.

Align the matchmarks of the crankshaft timing pulley with that of the front oil seal retainer.

Fig. 20 Aligning camshaft timing pulley & front plate

Align the matchmarks of the camshaft timing pulley with that of the front plate.

Note: At this point the No.4 cylinder comes to its compression, top dead center.

Lay the timing belt over the crank pulley, oil pump pulley, cam pulley, and tension pulley in the indicated order, avoiding any loosening between them.

Loosen bolt "B" to allow the tension spring to tighten the belt.
Temporarily tighten bolt "B".
Temporarily attach the crank pulley.

Turn the crankshaft two revolutions in the opposite direction of normal rotation to align the crankshaft matchmarks with the crankshaft timing pulley matchmarks.
Loosen bolt "B" and tighten the belt with the tension pulley.
Tighten bolt "B" to the specified torque.
