Cylinder Head Distortion
SPECIAL TOOLS
| Feeler Gauge Set 303-D027 (D81L-4201-A) or equivalent |
NOTE:
Refer to the ENGINE MECHANICAL - 1.6L
for the specification.
- Using a Straightedge and a Feeler Gauge Set, inspect the cylinder head for flatness in the sequence shown in illustration.
NOTE:
Make sure all cylinder head surfaces are clear of any gasket material, silicone sealant, oil and coolant. The cylinder head surface must be clean and dry before running a flatness check.
NOTE:
Use a Straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of length, such as Snap-On® GA438A or equivalent. For example, if the Straightedge is 61 cm (24 in) long, the machined edge must be flat within 0.010 mm (0.0004 in) from end to end.
