- remove the upper part of the air filter 1 (pic. 202);
- disconnect plug 5 of the mass air flow sensor and plug 7 of the heating element;
- remove from the cylinder head valve 10 of the crankcase ventilation system and the ventilation hose 11 leading to the solenoid valve 13 of the activated carbon cleaning system from the top of the intake manifold;
- disconnect high voltage wires (VN) from spark plugs (this requires a special tool 3 277 A);
Pic. 201. The top and bottom parts of an inlet collector and the details located nearby: 1 - the upper part of the intake manifold; 2 - HV wire guide; 3 - sealing ring; 4 - fuel supply hose; 5 - fuel return hose; 6 - fuel distribution line; 7 - bolt, 10 Nm; 8 - the lower part of the intake manifold; 9 - gasket, replace; 10 - nozzle; 11 - O-ring; 12 - bolt, 25 Nm; 13 - lifting eye; 14 - secondary air supply valve bracket; 15 - secondary air supply valve; 16 - vacuum hose; 17 - plug, blue; 18 - clamps; 19 - fuel pressure regulator; 20 - plug, black; 21 - guide sleeve; 22 - plug, black; 23 - temperature sensor; 24 - T-shaped fitting; 25 - vacuum hose, to the brake booster
- remove wire guide HV 2 (pic. 201) from the front and opposite side of the intake manifold 1;
Pic. 200. Details installed near the throttle body: 1 - the upper part of the intake manifold; 2 - cable guide; 3 - bolt, 10 Nm; 4 - rear right support between the upper part of the intake manifold and the cylinder head; 5 - bolt, 25 Nm; 6 - vacuum hose, from the valve of the crankcase ventilation system; 7 - ventilation hose, from the cleaning system with activated carbon; 8 - T-shaped fitting; 9 - throttle body; 10 - plug block, black, 8 connectors; 11 - gasket, should be replaced; 12 - throttle cable support; 13 - connecting element, 35 Nm (for EGR valve); 14 - «mass» cable; 15 - left rear support between the upper part of the intake manifold and the cylinder head
- remove the throttle cable together with support 12 (pic. 200) throttle actuator, but do it in such a way as not to remove the cable clamp;
- mark and remove the coolant hoses from the throttle body. In this case, the cooling system should not be under pressure;
- disconnect the fuel lines from the cylinder head;
- open the fuel tank cap for a while (to relieve excess pressure), then cover the hose connections with a thick cloth and slowly disconnect the hoses. If the fuel still splashes, then a rag will hold it;
Pic. 203. Disconnecting the vacuum hose of the secondary air inlet valve
- disconnect the vacuum hose (pic. 203, shown by arrow) a secondary air intake valve between the fuel pressure regulator and the top of the intake manifold;
- disconnect the vacuum hose going to the brake booster;
- unscrew both rear brackets between the top of the intake manifold and the cylinder head;
- unscrew the EGR valve hose on the top of the intake manifold;
- unscrew the dipstick guide tube from the bottom of the intake manifold;
- remove the upper part of the intake manifold along with the throttle body (when installing, pay attention to the location of the guide bushings) and plug open inlets immediately;
- disconnect the electrical wires from the injectors, from the oil pressure switch and from the oil temperature sensor;
- remove the nozzles together with the distribution fuel line;
- remove the injector clamps and the injectors themselves. If the nozzle sits very firmly in its place, then under its body you can substitute a 16 mm open-end wrench and use it to squeeze out the nozzle
- Remove the O-rings from both ends of the injector and discard immediately.
Attention! When removing the injectors, be careful not to damage the connector plugs and atomizers. The injectors don't work.
Attention! Do not allow engine oil to enter the injector.
Install the injectors in the reverse order of removal. Lubricate new O-rings with clean engine oil.
