Attention! Proceed with the procedure only after the final cooling of the power unit.
Upper pipeline
1. Relieve the pressure in the supply system (see chapter Power and exhaust systems).
2. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system! 3. Disconnect the intake duct, throttle linkages, and your hoses and wiring from the throttle body (see chapter Power and exhaust systems). Clog the coolant path hoses connected to the throttle body.
4. Remove from the inlet pipeline all plastic covers provided by a design.
5. Acting in the reverse order indicated in the illustration, give the fixing bolts and nuts and remove the pipeline with the throttle body fixed to it.
6. Before installing the top piping, thoroughly clean the mating surfaces of the bottom piping to remove all traces of old gasket material and sealant. Wipe the surfaces with a cloth soaked in acetone. Place a new gasket on the three mounting studs on the lower piping, then install the upper piping and tighten the fasteners to the correct torque in the specified order. Check coolant level, correct if necessary (see chapter Settings and ongoing maintenance).
Lower pipeline
1. Remove the steering pump (see chapter Suspension and steering) and not, disconnecting the hoses, take it to the side.
2. Having previously marked, disconnect the electrical wiring from the fuel injection injectors. Remove from the bottom inlet pipeline fuel highways (see chapter Power and exhaust systems).
3. Give fixing bolts and nuts and remove both sections of the bottom inlet pipeline from heads of cylinders. If any of the sections "got used to" and does not lend itself to separation, tap it around the perimeter with a hammer.
Attention! In no case do not attempt to separate the pipeline by levering its sections by the mating surfaces - any mechanical damage to the latter can lead to the development of leaks.
The fuel injection injectors can be left in their original positions.
4. Using a scraper made of a relatively soft material, carefully clean the mating surfaces of the pipeline and cylinder heads from sealant residues and traces of old gasket material, then wipe them with a rag soaked in acetone.
5. Lay new linings, then establish on heads of cylinders sections of the lower inlet pipeline.
Attention! Make sure that the gaskets are properly seated on the guide pins. Screw the fasteners of the sections.
6. Tighten the fastener to the required torque in three steps. To avoid the development of deformations, move from the center of the sections to their edges, moving from one fastener to another in a diagonal order.
7. Further installation is carried out in the reverse order to the dismantling of the components.
8. Check the coolant level, make appropriate adjustments if necessary (see chapter Settings and ongoing maintenance).
9. Start the engine and check for fuel and coolant leaks. Also make sure there are no vacuum losses.
