Intake Manifold: Testing and Inspection

2GR-FE ENGINE MECHANICAL: ENGINE ASSEMBLY:

INSPECTION
1. INSPECT INTAKE AIR SURGE TANK ASSEMBLY






(a) Using a precision straightedge and feeler gauge, measure the warpage on the contact surface of the intake manifold.
Maximum warpage:
2.5 mm (0.098 in.)
If the warpage is greater than the maximum, replace the surge tank.
2. INSPECT INTAKE MANIFOLD






(a) Cylinder head side:
(1) Using a precision straightedge and feeler gauge, measure the surface contacting the cylinder head for warpage.
Maximum warpage:
0.1 mm (0.003 in.)
If the warpage is greater than the maximum, replace the intake manifold.
(b) Surge tank side:
(1) Using a precision straightedge and feeler gauge, measure the surface contacting the surge tank for warpage.
Maximum warpage:
0.1 mm (0.003 in.)
If the warpage is greater than the maximum, replace the intake manifold.
