Kia Sorento: Cylinder Block Inspection

1.	Remove gasket material. Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block.

2.	Clean cylinder block Using a soft brush and solvent, thoroughly clean the cylinder block.

Inspect top surface of cylinder block for flatness.

Using a precision straight edge and feeler gauge, measure the contacting surface of the cylinder block and the manifolds for warpage..

Flatness of cylinder block gasket surface

Standard : Less than 0.05 mm (0.0019 in.) for all

Less than 0.02 mm (0.0007 in.) for 100 mm (3.9370 in.) x 100 mm (3.9370 in.)

4.	Inspect cylinder bore diameter. Visually check the cylinder for vertical scratchs. If deep scratches are present, replace the cylinder block.

Inspect cylinder bore diameter.

Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial directions.

Standard diameter :

88.00 ~ 88.03 mm (3.4645 ~ 3.4657 in.)

Measure position points (from the bottom of the cylinder block)

: 110.7 mm (4.3582 in.) / 160 mm (6.2992 in.) / 210 mm (8.2677 in.)

Check the cylinder bore size code on the cylinder block.

Cylinder Bore Inner Diameter

Size Code	Cylinder Bore Inner Diameter
A	88.00 ~ 88.01 mm (3.4645 ~ 3.4649 in.)
B	88.01 ~ 88.02 mm (3.4649 ~ 3.4653 in.)
C	88.02 ~ 88.03 mm (3.4653 ~ 3.4657 in.)

Check the piston size code on the piston top face.

Stamp the grade mark of basic diameter with rubber stamp.

Piston Outer Diameter

Select the piston related to cylinder bore class.

Clearance : 0.020 ~ 0.040 mm (0.00079 ~ 0.00157 in.)

• Use fender covers to avoid damaging painted surfaces. • ...

1. Install the oil jet (A). Tightening torque : 24.5 ~ 29.4 N.m (2.5 ~ 3.0 kgf.m, 18.1 ~ 21.7 lb-ft) ...
