Year and type of engine, inline 4 or V6?

If a 5SFE model use the procedure below.

Rotate the crank until the TDC pulley mark lines up with the 0 degree mark on the timing cover and the No 1 piston is at TDC on the compression stoke. If the engine has a distributor remove the cap and look at the rotor. When in the correct position the rotor metal probe should very close (10 degrees) to the No 1 spark plug wire electrode position if the cap were installed.

Look at the face of the cam pulley. There is a hole in one of the spokes. When looking at the front face center the hole on a mark (notch) on top of the front upper cam bearing mount. This is the final setting method.

The rotor should still be within 10 degrees of the No 1 electrode.

Rotate the crank 2 complete rotations CW and recheck the hole/notch alignment.
