id074000908219

  Caution

  • If the negative battery cable is disconnected during the purge cycle of the water heater unit, the gas in the unit may not be properly scavenged, causing white smoke (unburnt gas) to emit from the exhaust pipe. Before disconnecting the negative battery cable, verify that the water heater unit is not operating (no blower fan operation noise).

1. Complete the "BEFORE REPAIR PROCEDURE". (See BEFORE REPAIR PROCEDURE [MZR-CD (RF Turbo)].)

2. Disconnect the negative battery cable.

3. Drain the engine coolant.

4. Remove the fuel filter with the pipes still connected, and fix the fuel filter using a rope so that it is out of the way.

5. Remove in the order indicated in the table.

6. Install in the reverse order of removal.

7. Complete the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].)

8. Refill the engine coolant.
