Remove the surge tank (A).
Tightening torque
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
Disconnect the LH injector connectors.
Remove the delivery pipe & injector assembly (A).
Remove the intake the manifold (A).
Be sure to drain the engine coolant before removing the intake manifold.
If any coolant drained from the cylinder head vent hole has entered the intake port. This can potentially lead to engine trouble.
Installation is reverse order of removal.
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:Nut- 18.6 ~ 23.5N.m (1.9~2.4kgf.m, 13.7~17.4lb-ft)
Bolt -26.5 ~ 31.4N.m (2.7~3.2kgf.m, 19.5~23.1lb-ft)
Step 3: Repeat 2nd step twice or more.
a ~ h : 1st step order
1 ~ 8 : 2nd step order
Confirm the manifold gasket identification mark (LH, RH) and be careful of the installation direction.
