3.3.9. Inlet collector


1. Lower pressure in fuel system and disconnect a wire of the minus plug of the accumulator.
2. Merge cooling liquid.
3. Remove an airintaking branch pipe.
4. Disconnect ropes, hoses and wires from the throttle case.
5. In a back part of a final collector disconnect a wire (And), two wires of fuel injectors (In), a tube of supply of fuel (C) and a vacuum hose from a regulator of pressure of fuel (D).
6. Disconnect a rope of a butterfly valve (And), two wires of the electromagnetic valve (In) and an arm on which sockets are fixed. A bolt (C) is one of arm bolts.
7. Disconnect wires from spark plugs.
8. Unscrew bolts and braid collector nuts. Remove a collector.


1. Clean off the remains of old laying and a deposit from being joined surfaces of a collector and a head of cylinders.
2. Under an inlet collector there are two perepuskny tubes of cooling liquid. Carrying out maintenance of these tubes is complicated, therefore, each time when you remove a collector, surely replace a rubber hose of cooling liquid and hose clips.
3. Establish new laying of an inlet collector and a collector.
4. Tighten bolts and collector nuts in three steps till the demanded moment of an inhaling.
5. Establish the remained details, get the engine and check the engine on existence of leaks.
