INSTALLATION
Installation is in the reverse order of removal.
Manual Transaxle
CAUTION: When installing the transaxle, do not allow the transaxle input shaft to contact the clutch cover.
^ When installing the transaxle to the engine, use the specified tightening torque in the order shown.
5 A/T
^ When installing the transaxle to the engine, use the specified tightening torque in the numerical sequence as shown.
^ After installation, check the transaxle oil level, and check for any leaks and any loose mechanisms.
^ Install crankshaft position sensor (POS).
Crankshaft position sensor (POS) bolt : 8.4 - 10.8 Nm (0.86 - 0.98 kg-m, 74.6 - 95.5 inch lbs.)

INSPECTION AFTER INSTALLATION
^ Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to "RECOMMENDED FLUIDS AND LUBRICANTS".
^ Use procedure below to check for fuel leakage.
^ Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
^ Start engine. With engine speed increased, check again for fuel leakage at connection points.
^ Run engine to check for unusual noise and vibration.
^ Warm up engine thoroughly to make sure there is no leakage of Fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
^ Bleed air from passages in lines and hoses, such as in cooling system. After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
