Intake Manifold

3UZ-FE INTAKE: INTAKE MANIFOLD: INSPECTION

INSPECTION

1. INSPECT INTAKE MANIFOLD SUB-ASSEMBLY UPPER





(a) Using a precision straightedge and feeler gauge, measure the surface contacting the intake manifold upper for warpage.
Maximum warpage:
0.10 mm (0.0039 in.)
If the warpage is greater than the maximum, replace the intake manifold sub-assembly upper.
2. INSPECT INTAKE MANIFOLD SUB-ASSEMBLY LOWER





(a) Using a precision straightedge and feeler gauge, measure the surface contacting the cylinder head and intake manifold for warpage.
Maximum warpage:
0.15 mm (0.0059 in.)
If the warpage is greater than the maximum, replace the intake manifold sub-assembly lower.
