Attention! It is assumed that the work is carried out with the ignition distributor correctly installed (if the distributor is provided).
Attention! If it is necessary to restore the correct position of the distributor, determine the engine stroke by feeling the compression in the 1st cylinder with the spark plug removed, then align the ignition timing marks (see below).
Attention! The installation procedure is the same for 2F, 3F-E and twin-shaft overhead valve 1FZ-FE engines.
1. Setting the piston of the 1st cylinder to TDC of the compression stroke is necessary to perform adjustment and setup work (valve adjustment, ignition timing, etc.).
2. Move the transmission selector to the Neutral or Park position (on automatic transmission) or to a neutral position (with manual transmission). Remove the central high-voltage wire from the ignition distributor and connect it to ground.
3. The crankshaft is turned clockwise using a key on the pulley bolt head.
4. Using the wire from the spark plug of the 1st cylinder, find the corresponding terminal on the distributor cap and mark it with a line on the housing. Remove the distributor cap.

5. Turn the crankshaft clockwise with a wrench on the pulley bolt head until the marks on the flywheel are aligned (the leading disk of the torque converter) with a pointer (on engines 2F and 3F-E, photo on the left) or notches on the crankshaft pulley with the mark "0" on a fixed scale (on engines 1FZ-FE, photo on the right).
6. If the distributor runner pointer is opposite the mark on the distributor housing, then the piston of the 1st cylinder is at TDC of the compression stroke. If the runner is turned 180° from the mark, then turn the crankshaft by 1 revolution, after which the piston of the 1st cylinder will be set at TDC of the compression stroke. In this case, the marks on the scale and pulley should be aligned, and the runner pointer should be opposite the mark indicating the output of the 1st cylinder.
Attention! If it is not possible to set the piston of the 1st cylinder to the TDC of the compression stroke in this way, the reasons are incorrect installation of the ignition distributor, gears or camshaft drive chain.
7. Mark the terminals of the other wires in accordance with the engine operating order. By turning the crankshaft further clockwise relative to the TDC position of the 1st cylinder, you can set the piston of each cylinder to TDC by aligning the runner with the terminal marks.
