This procedure applies to M20 and M40 engines only.
If your vehicle's radio is equipped with an anti-theft system, make sure you enter the correct code before disconnecting the battery.
If the instrument cluster displays the wrong language after connecting the battery, refer to Section Anti-theft audio system and instrument cluster language, which describes the procedure for installing the required language.
1. Disconnect the negative battery cable.
2. Remove the drive coupling and fan shroud (see chapter Cooling system).
3. On the M20 engine, remove the radiator (see chapter Cooling system).
4. Remove the fan drive belt pulley.
5. Disconnect the standard sensor wiring, if equipped, that runs through the front of the timing belt cover and move it aside.
6. If the distributor cap is installed directly on the upper timing belt cover, remove the distributor cap, rotor, and black plastic cover located under the rotor.
