Removal, check and installation of an inlet collector

Withdrawal

Disconnect from the throttle body hose crankcase ventilation (Fig. 2.328).

Disconnect a cable of an accelerator pedal (Fig. 2.329).

Disconnect from the throttle body coolant hose.

Disconnect the hose valve PCV and brake booster vacuum hose.

Remove the vacuum hose fitting (Fig. 2.330).

Remove the support bracket of the receiver intake manifold (Fig. 2.331).

Before disconnecting the fuel hose from the high pressure fuel manifold relieve residual pressure in the system.

Disconnect the fuel manifold fuel hoses (Fig. 2.332).

Remove the receiver and the intake manifold gasket (Fig. 2.333).

Disconnect the harness connector at the fuel injectors (Fig. 2.334).

Remove the fuel manifold with injectors and fuel pressure regulator (Fig. 2.335).

Disconnect the connector coolant temperature sensor (Fig. 2.336).

Remove the intake manifold assembly and gasket (Fig. 2.337).

Check intake manifold and receiver

Check the details for cracks and damage.

Check the condition of the air passage channel, channel outlet and inlet coolant nozzles and vacuum hoses. Clean if necessary

Using Rulers and feeler gauge, measure the warping of mating plane intake manifold (Fig. 2.338).

The nominal value of flatness: less than 0.15 mm.

Limit: 0.20 mm.

Setting

Installation is carried out in reverse order.

Torque:

Intake manifold - 19-21 Nm.

Receiver intake manifold - 15-20 Nm.
