Replacing the intake manifold sealing rings (Priora 2170)

To seal the joint between the flanges of the cylinder head and the intake manifold, as well as between the flanges of the throttle assembly and the intake manifold, sealing rings are installed in the grooves of the intake manifold pipes. If the tightness of these rings is broken, the engine runs unevenly ("troits").



You will need: flat- and Phillips-head screwdrivers, nippers or a knife, 10 and 13 mm wrenches.

1. Raise the hood and disconnect the wire from the negative terminal of the battery.

2. Remove the decorative engine cover (see "Removing and installing the decorative engine cover").

3. Remove the throttle assembly from the intake manifold (see "Removing and installing the throttle assembly").

8. Install new sealing rings into the grooves of the manifold.
