Click on the following free direct Link. It has the correct Serpentine and Drive Belt Diagrams for your 1993 Toyota Pickup, with either the 2.4L SOHC In-Line 4-Cylinder, 2.7L DOHC In-Line 4-Cylinder, or 3.0L SOHC V6 Engine with the different Engine Options (AC/No AC etc.).

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.
the trans will not allow overdrive until coolant reaches roughly 180 degrees, if the guage shows cool and the trans is not upshifting, or downshifts to third while driving. the problem is either a sticking (or missing) thermostat. follow the lower radiator hose to the engine and find the three 12mm nuts, remove these to get to it. a new toyota t-stat will have a little bleed valve on its face. position it upwards when installing. hope this is helpful.
P.S. Happy New Year
Please send me your e-mail address; I will send you the complete timing proceedure; the file I have is a .pdf, and FixYa will not let me upload a .pdf to the FixYa site. I suspect that your cam timing is off on the passenger side of the engine. You want the specs for a 93 V6, correct?
