Installation Procedure
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.

duct (1) to the throttle body and air cleaner assembly.
Tighten
Tighten the clamp to 2 N·m (18 lb ft).
- Install the IAT sensor electrical connector to the IAT Sensor.
- Refill the radiator to replace the lost coolant. Refer to
Cooling System Draining and Filling
.
- Install the fuel injection sight shield. Refer to
Fuel Injector Sight Shield Replacement
.
