NOTE:
When torquing the screw of the hose band (H), do not overtighten the screw to a torque of 3.0 N·m (0.31 kgf·m, 2.2lbf·ft) or more.
After tightening the screw of the hose band, make sure the clearance (I) is less than 0.04 in (1.0 mm).

3. Engine Coolant - Refill

Refill the radiator with engine coolant.

5. PCM - Idle Learn
