DRIVE BELTS : Checking Drive BeltsINFOID:0000000009464553
WARNING:
Inspect and check the drive belts with the engine off.
1. Inspect belt for cracks, fraying, wear or o il adhesion. If necessary, replace with a new one.
2. Rotate the crankshaft pulley two times then ensure t he drive belt auto-tensioner is within the possible use
range.
NOTE:
Inspect drive belt tension when engine is cold.
DRIVE BELTS : Tension AdjustmentINFOID:0000000009464554
Belt tension is not manually adjustable, it is aut omatically adjusted by the drive belt auto-tensioner.

SYSTEM
TACHOMETER : System Diagram
INFOID:0000000009461677
TACHOMETER : System DescriptionINFOID:0000000009461678
The crank position sensor sends a crankshaft positi on signal to the ECM. The ECM provides an engine speed
signal to the combination meter via CAN communication lines.
The tachometer indicates engine speed in revolutions per minute (rpm).
ENGINE COOLANT TEMPERATURE GAUGE
ENGINE COOLANT TEMPERATURE GAUGE : System DiagramINFOID:0000000009461679
ENGINE COOLANT TEMPERATURE GAUGE : System DescriptionINFOID:0000000009461680
The engine coolant temperature sensor sends an engine coolant temperature signal to the ECM. The ECM
provides an engine coolant temperature signal to t he combination meter via CAN communication lines.
The engine coolant temperature gauge indicates the engine coolant temperature.
FUEL GAUGE
FUEL GAUGE : System DiagramINFOID:0000000009461681
FUEL GAUGE : System DescriptionINFOID:0000000009461682
The fuel level sensor unit sends a variable resistor signal to the combination meter. The fuel gauge indicates
the approximate fuel level in the fuel tank.

2. Disconnect the transaxle harness connectors.
3. Disconnect the CVT oil warmer water hoses from engine side. Refer to TM-199, "WATER HOSE :
Removal and Installation".
4. Remove the transaxle to engine and engine to transaxle bolts.
5. Remove the CVT fluid charging pipe.
6. Separate the engine from the transaxle assembly. Refer to EM-84, "Removal and Installation"
.
NOTE:
Using paint, put matching marks on the drive plate and torque converter when removing the torque con-
verter to drive plate nuts.
7. Remove transmission bracket.
INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Write down the serial number of the new transaxle assembly.
CAUTION:
• When replacing an engine or tr ansaxle you must make sure any dowels are installed correctly during
re-assembly.
• Improper alignment caused by missing dowels m ay cause vibration, oil leaks or breakage of driv-
etrain components.
• Do not reuse O-rings or copper sealing washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-62, "Removal and Installa-
tion".
• After converter is installed to drive plate, rota te crankshaft several turns to check that CVT rotates
freely without binding.
• When installing the CVT to the engine, align the ma tching mark on the drive plate with the matching
mark on the torque converter.
When installing the CVT to the engine, attach the bolts in accor-
dance with the following standard.
• (A) : Transaxle assembly to engine assembly.
• (B) : Engine assembly to transaxle assembly.

TRANSAXLE ASSEMBLY
1. Remove the engine and transaxle with the front suspension member as a unit. Refer to
EM-220,
"Removal and Installation".
2. Disconnect the transaxle harness connectors.
3. Disconnect the CVT oil warmer water hoses from engine side. Refer to TM-400, "WATER HOSE :
Removal and Installation".
4. Remove the CVT fluid charging pipe.
5. Remove the transaxle to engine and engine to transaxle bolts.
6. Separate the engine from the transaxle and remove the engine from the front suspension member. Refer to EM-220, "Removal and Installation"
.
NOTE:
Using paint, put matching marks on the drive plat e and torque converter when removing the torque con-
verter to drive plate nuts.
7. Remove transmission bracket.
8. Lift the transaxle from the front suspension member.
INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Write down the serial number of the new transaxle assembly.
CAUTION:
• When replacing an engine or transaxle you must m ake sure any dowels are installed correctly during
re-assembly
• Improper alignment caused by missing dowels m ay cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings or copper sealing washers.
• When turning crankshaft, turn it clockwi se as viewed from the front of the engine.
• When tightening the nuts for the torque converte r while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-174, "Removal and Instal-
lation".
• After converter is installed to drive plate, rota te crankshaft several turns to check that CVT rotates
freely without binding.
• When installing the CVT to the en gine, align the matching mark on the drive plate with the matching
mark on the torque converter.
When installing CVT assembly to th e engine assembly, attach the bolts in accordance with the follow-
ing standard.
