Exhaust Manifold: Testing and Inspection

2GR-FE ENGINE MECHANICAL: ENGINE ASSEMBLY: INSPECTION

1. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY LH

(a) Using a precision straightedge and feeler gauge, measure the warpage on the contact surface of the cylinder head.





Maximum warpage:

0.7 mm (0.028 in.)

HINT
The maximum allowable warpage of each installation surface is 0.3 mm (0.012 in.).

If the warpage is greater than the maximum, replace the manifold.

2. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY RH

(a) Using a precision straightedge and feeler gauge, measure the warpage on the contact surface of the cylinder head.





Maximum warpage:

0.7 mm (0.028 in.)

HINT
The maximum allowable warpage of each installation surface is 0.3 mm (0.012 in.).

If the warpage is greater than the maximum, replace the manifold.
