INSTALLATION
Installation in the reverse order of removal.
Intake Manifold and Fuel Tube Protector
• If stud bolts were removed, install them and tighten to the specified torque below.
• Tighten in numerical order as shown.
NOTE:
No. 6 means double tightening of bolt No. 1.
Electric Throttle Control Actuator
• Tighten bolts equally and diagonally in several steps and in numer-
ical order as shown.
• Perform the “Throttle Valve Closed Position Learning” when har-
ness connector of electric throttle control actuator is disconnected.
EC-123, "Throttle Valve Closed Position Learning"
• Perform the “Idle Air Volume Learning” and “Throttle Valve Closed
Position Learning” when electric throttle control actuator is
replaced. Refer to
EC-124, "Idle Air Volume Learning"
.
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
MA-16, "FOR USA AND CANADA : Fluids and Lubricants"
(United
States and Canada).
• 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 leak-
age 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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• 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 spec-
ified level, if necessary.
