Illustration	Tool Name	Tool Number
	Feeler Gauge Set	303-D027 (D81L-4201-A) or equivalent

NOTE: Refer to ENGINE - 2.0L AND 2.3L article for the specification.

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.

Use a straightedge and a feeler gauge to inspect the cylinder block for flatness.
