Intake Manifold and EGR Valve Installation

1. Connect the vacuum pump and gauge to the actuator of EGR valve assembly.

1. Apply 0 kPa to 25 kPa (0.25 kgf/cm2, 1.8 lbf/ft) vacuum and check EGR valve moving condition.

1. If there is abnormal moving conditions on the EGR valve, replace the EGR valve assembly.

1. Inspect VSS (Variable Swirl System) for damage or any other problems and push the valve with your finger to inspect normal condition or valve sticking.

1. Inspect the EGR valve for damage or any other problems.

1. Apply liquid gasket to the VSS.

1. Install the intake manifold assembly with gasket to cylinder head.
