Repair Procedures
Removal and Installation
1. Remove the surge tank.
2. Remove the low pressure fuel line.
3. Remove the intake manifold (A).
NOTE:
- Cover the cylinder head intake port with a clean woven stuff or vinyl cover to prevent foreign materials from entering.
- Make sure the engine and radiator are cool to the touch.
- Remove radiator cap.
- Loosen the drain plug and drain the coolant.
- Tighten the radiator drain plug securely.
CAUTION:
Drain the engine coolant before removing the intake manifold.
Otherwise, engine coolant may enter into the intake port from the vent holes of the cylinder head and this can cause problems in the engine combustion chambers.
4. Install in the reverse order of removal.
NOTE:
Tighten the intake manifold bolts and nuts, in several passes as below.
Tightening torque
Step 1: 3.9 - 5.9N.m (0.4 - 0.6kgf.m, 2.9 - 4.3lb-ft)
Step 2: 26.5 - 31.4N.m (2.7 - 3.2kgf.m, 19.5 - 23.1lb-ft)
Step 3: Repeat 2nd step twice or more.
CAUTION:
Fill the engine coolant after installing intake manifold and check coolant level.
