Replacing a refrigerator exhaust gas recirculation (2.0 liter engine

Fig. 2.318. The design of the

exhaust system (Z 20 LEL): 1 endpoint muffler with exhaust pipe, 2 - central exhaust pipe with a central silencer, 3 - Front exhaust pipe with a flexible tube

The chart below shows the position and location of individual components of the exhaust system (Fig. 2.318).

Withdrawal

Open the hood. Disconnect the battery. Disconnect the grounding connector on the grounding clamp. Raise the car completely.

Fig. 2.319. Lower engine compartment lid: 1 - cover

Remove the bottom cover of the engine compartment by unscrewing the mounting bolts 10 and removing the 4 rivets (Fig. 2.319). Place the bottom of the container for drainage. Drain the coolant. To do this, loosen the drain bolt on the radiator and collect coolant. Tighten the drain bolt Lower the car completely. Remove the engine.

Fig. 2.320. Removing hose air

pressurization: 1 - hose

Remove the hose, air pressurization, removing 2 clamp (Fig. 2.320). Remove the battery.

Fig. 2.321. Removing the pipe

cooling system: 1 - screw fixing the lower rubber bearing, 2, 3, 4 Brackets

Remove the pipe cooling system (Fig. 2.321). Unlock the 2 coolant hose from the bracket by removing the mounting bracket.

sensor: 1 - Sensor 2 - wiring harness connector

Fig. 2.323. Housing Thermostat: 1

- body, 2 - bolts fastening

Remove the thermostat housing (see Figure 2.323). 4 Disconnect the coolant hose. 4 Remove the clamp and unscrew the 2 screws fastening.

Fig. 2.324. Hose Air Pressurization: 1 - hose

Remove the hose, air pressurization, removing 2 clamp (Fig. 2.324).

Disconnect the coolant hose from the pipe cooling system, removing the clamp (Fig. 2.325).

Fig. 2.326. Coolant hoses: 1 - hose

coolant main pipe cooling system, 2 - Lower coolant hose pipe cooling system, 3 - hose coolant cooler exhaust gas recirculation

3 Disconnect the coolant hose (Fig. 2.326). Disconnect the coolant hose from the main pipeline of the cooling system. Disconnect the coolant hose from the bottom of the pipe cooling system. Disconnect the coolant hose from the exhaust gas recirculation cooler. Disconnect the EGR tube from exhaust manifold production. Remove refrigerator recycling of exhaust gases. Disconnect the tube from the exhaust gas recirculation valve exhaust gas recirculation.

Setting

Set refrigerator recycling of exhaust gases. Tighten the 2 bolts moment 25 Nm Connect the EGR tube to the exhaust manifold. Install a new gasket. Tighten the 2 screws. Tighten the clamp. Attach the tube to the exhaust gas recirculation valve exhaust gas recirculation. Install a new gasket. Tighten the 2 screws. Tighten the clamp. 3 Connect the coolant hose. Attach the coolant hose to the upper pipe cooling system. Attach the hose to the lower coolant pipe cooling system. Attach the coolant hose to the refrigerator recycling of exhaust gases. Attach the hose to the coolant pipe cooling system. Attach the hose to the turbocharger boost air duct pressurization. Tighten the clamp 2 point 3.5 Nm Clean the sealing surface. Peel 2 Threads. Set the thermostat housing and new gasket.
