DRAIN COOLANT (for Inverter)
Note
Do not reuse the drained coolant because it may contain foreign matter.
Collect the drained coolant and measure its volume to establish a benchmark. When adding coolant, make sure to add more coolant than the measured amount.
Remove the reserve tank cap.
CAUTION:
To avoid the danger of being burned, do not remove the reserve tank cap while the coolant for the inverter is still hot.
Using a hexagon wrench (10 mm), remove the drain plug indicated in the illustration and drain the coolant.
CAUTION:
Use caution when handling coolant immediately after driving or in summer because it may be hot.

Remove the bolt.
DISCONNECT FRAME WIRE
CAUTION:
Wear insulated gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Disconnect the harness clamp.
Using an insulated tool, remove the 4 bolts, and disconnect the frame wire (high voltage cables of the hybrid battery) from the inverter with converter assembly.
DISCONNECT GENERATOR CABLE
CAUTION:
Wear insulated gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Turn back the wire harness cover and release the generator cable.
Using an insulated tool, remove the 5 bolts, and disconnect the high voltage cables of the generator cable (MG1) from the inverter with converter assembly.
DISCONNECT MOTOR CABLE
CAUTION:
Wear insulated gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Disconnect the harness clamp.
Using an insulated tool, remove the 5 bolts, and disconnect the high voltage cables of the motor cable (MG2) from the inverter with converter assembly.
DISCONNECT NO. 2 ENGINE WIRE
CAUTION:
Wear insulated gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Using an insulated tool, remove the 4 bolts, and disconnect the No. 2 engine wire (high voltage cables for the air conditioning compressor) from the inverter with converter assembly.
Disconnect the harness clamp.
INSTALL INVERTER COVER
CAUTION:
Wear insulated gloves.
| *1 | Interlock |
Temporarily install the inverter cover with the 9 bolts to prevent any foreign matter or water from entering the inverter with converter assembly.
Note
Make sure that the interlock is fully engaged.
Do not allow any foreign matter or water to enter the inverter with converter assembly.
DISCONNECT NO. 2 ENGINE ROOM WIRE
Remove the relay block cover.
Release the 2 clamps, and remove the No. 1 relay block cover.
Remove the bolt from the No. 2 engine room wire.
Release the 2 claws, and disconnect the No. 2 engine room wire.
Connect the No. 2 engine room wire to the protector.
DISCONNECT NO. 1 INVERTER COOLING HOSE
Release the retainer and disconnect the No. 1 inverter cooling hose from the inverter with converter assembly.
| *1 | Retainer |
Put pieces of cloth into the pipes and in the disconnected hoses, or cover the pipes and hoses with plastic bags as shown in the illustration to prevent foreign matter from entering the cooling system and to prevent coolant from spilling near the inverter with converter assembly.
REMOVE NO. 6 INVERTER COOLING HOSE
| *1 | Retainer |
Release the retainer and disconnect the No. 6 inverter cooling hose from the inverter with converter assembly.
Put pieces of cloth into the pipes and in the disconnected hoses, or cover the pipes and hoses with plastic bags as shown in the illustration to prevent foreign matter from entering the cooling system and to prevent coolant from spilling near the inverter with converter assembly.
REMOVE INVERTER WITH CONVERTER ASSEMBLY
CAUTION:
Wear insulated gloves.
Remove the 3 bolts and inverter with converter assembly.
Note
Since the inverter with converter assembly is very heavy, 2 people are needed to remove the inverter with converter assembly. When removing the inverter with converter assembly, do not damage the parts around it.
To prevent damage, do not hold the inverter with converter assembly by the connectors.
To prevent damage due to static electricity, do not touch the terminals of the disconnected connectors.
Even after the coolant is drained, coolant remains in the inverter due to its internal structure. Therefore, seal or cover the pipes when removing the inverter so that coolant does not spill out.
