How do you line up the timing marks on a 1994 Isuzu Trooper 3.2?

Answer 1

there is an excellent resource for this on an Aussie jackaroo site, here:

another guide is here:

http://www.jasperengines.com/pdf/Isuzu_Timing_Belt.pdf

both have diagrams which clearly illustrate the belt and pulley alignment.

as for the alignment marks:

before you put the belt on, align the crank pulley key/keyway with the oil pump (on driver's side of motor, has alignment mark that looks like a dash - )

in aligning the camshafts, there are nice lines/marks on the gears themselves, but the marks they line up with are small dots on the black,steel timing belt covers between the gears and the heads.

on the belt, the dotted line goes on the crankshaft pulley (there is an alignment mark on the gear that lines up) the two solid lines align with the marks on the camshafts. the words on the belt should be readable to you if you are standing in front of the truck, facing the engine.
