Exhaust Manifold: Testing and Inspection

3UZ-FE EXHAUST: EXHAUST MANIFOLD: INSPECTION

INSPECTION

1. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY (for Bank 2)





(a) Using a precision straightedge and feeler gauge, measure the exhaust manifold's cylinder head contact surface for warpage.
Maximum warpage:
0.50 mm (0.0197 in.)
If the warpage is greater than the maximum, replace the manifold.
2. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY (for Bank 1)
HINT: Use the same procedures described for the bank 2 side.
