MAGNET VALVE REMOVAL

PROCEDURE


  1. CAUTION

    Note


    • The coolant (Toyota genuine FC stack coolant) is an exclusive coolant.

    • The coolant (Toyota genuine FC stack coolant) cannot be reused, so when filling, be sure to fill with new coolant (Toyota genuine FC stack coolant).

    • To prevent degradation of coolant (Toyota genuine FC stack coolant) performance, do not add or fill any other substances such as tap water or battery electrolyte refill liquid.

    • Do not use cotton work gloves or other gloves that could shed fibers.

    • DO NOT use any container that has previously been used to fill substances such as oil.

    • To prevent foreign matter from contaminating the coolant (Toyota genuine FC stack coolant) passages, wash out the prepared container with tap water, then wipe away any water remaining inside the container before using it.

    • If the coolant (Toyota genuine FC stack coolant) passages are filled incorrectly, follow the countermeasures according to "Countermeasures when coolant (Toyota genuine FC stack coolant) passages are filled incorrectly".

    • When the vehicle is parked with the power switch off, if the FC control ECU judges that the FC stack temperature will go below 0°C, it activates the FC air compressor, hydrogen pump and FC cooling water pump for a maximum of 180 seconds and drains water from the FC stack assembly. When performing inspection or repairs with the power switch off (not On or Ready), disconnect the cable from the negative auxiliarybattery terminal before performing work.
