Kia Rio: Intake Manifold: Removal and Installation - Intake And Exhaust System - Engine Mechanical System - Kia Rio UB 2012-2021 Service ManualKia Rio: Intake Manifold: Removal and Installation

1.
Remove the engine cover.
2.
Disconnect the battery negative terminal.

Tightening torque :
Without battery sensor :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
With battery sensor :
4.0 ~ 6.0N.m (0.4 ~ 0.6kgf.m, 3.0 ~ 4.4lb-ft)

3.
Remove the air duct and the air cleaner assembly.
(Refer to Engine and transaxle assembly)
4.
Disconnect the injector extension connector (A), the VIS (Variable intake system) connector (B) and the PCSV (Purge control solenoid valve) connector (C).


5.
Disconnect the ETC (Electronic throttle control) connector (A) and the MAPS (Manifold absolute pressure sensor) & IATS (Intake air temperature sensor) connector (B).


6.
Disconnect the knock sensor connector (A).


7.
Disconnect the PCV (Positive crankcase ventilation) hose (A) and the PCSV (Purge control solenoid valve) hose (B).


8.
Disconnect the vacuum hose (A) and the throttle body coolant hoses (B).


9.
Unfasten the filler neck assembly mounting bolts (A).

Tightening torque :
6.9 ~ 10.8 N.m (0.7 ~ 1.1 kgf.m, 5.1 ~ 8.0 lb-ft)


10.
Remove the intake manifold (A) with the gasket (B).

Tightening torque :
18.6 ~ 23.5N.m (1.9 ~ 2.4kgf.m, 13.7 ~ 17.4lb-ft)



     
When installing, replace with new gaskets.
When installing the intake manifold, tighten the bolts and nuts with pre-torque first, and then tighten the bolts and nuts with specified torque in the sequence shown.
