Honda Accord

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

2. Dump pressure in a power supply system and disconnect electroconducting from injectors of injection of fuel. Disconnect gasoline pipe lines and remove fuel highways (see. Head of the Power supply system and release).
3. Empty cooling system, including the engine block (see. Head of Control and routine maintenance).
4. Remove the generator and the ignition distributor (see. Head engine Electric equipment).
5. Disconnect the grounding tire from the wall of the power unit turned to a gas-distributing belt.
6. Remove the steering pump (see. Head the Suspension bracket and a steering) and, without disconnecting hoses, shift it aside.
7. Remove the top inlet pipeline (see. Section Removal and installation of the inlet pipeline).
8. Remove final collectors (see. Section Removal and installation of final collectors).
9. Throw off a gas-distributing belt and remove cogwheels of a drive of GRM (see. Section Removal, check of a condition and installation of a gas-distributing belt and cogwheels of a drive of GRM).
10. Remove back covers of a gas-distributing belt (see. Section Removal, check of a condition and installation of camshafts).
11. Separate assembly of channels of an okhladitelny path.

12. Remove assemblies of yokes with axes (see. Section Removal, check of a condition and installation of assembly of yokes).

13. A face key in stages (on 1/4 turns for an approach) weaken bolts of fastening of a head of cylinders so that there was a reversing possibility their hands. Weakening of bolts should be made as it should be, the return to an order of their tightening.

14. Remove a head of cylinders from the engine. If the head does not separate from the block, it is possible to use the lever which should be got between molding ledges (at all do not hook a head under an interfaced surface).

15. Operating in the same order (see paragraphs with 12 on 14), remove the second head. Check planeness of both heads.

1. Carefully smooth out interfaced surfaces of heads and the block of cylinders. Having scratched out the remains of a material build laying and coal deposits, wipe surfaces the rags moistened in acetone. Existence on interfaced surfaces of a material of old laying at the moment of installation of a head can lead to violation of tightness of landing of laying and, as a result, development of leaks. Processing the block, закупорьте openings of cylinders rags in order to avoid hit in them small garbage and various extraneous subjects (as a last resort, carefully vacuum cylinders).
2. Check interfaced surfaces of heads and the block on existence of deep scratches, задиров and other damages. Easy defects can be eliminated by means of a fine-grained emery paper. In more serious cases the unique alternative is the pro-point or replacement of components.
3. A tap of the suitable size banish carving отверстияпод bolts of fastening of heads. Having finished pro-race, blow openings the compressed air. Serially clamping bolts in a vice for a head, walk on their carving lerky, - existence in rounds of a carving of old hermetic, dirt and products of corrosion results in discrepancy of real effort of a tightening of fixture to indications of the indicator of a dinamometrichesky key.

At work with reaped air do not forget to put on goggles!

4. Carefully clean jets of masloraspylitel, replace their sealing rings. Lay new sealing laying, putting on them on masloraspylitel and directing pins in the block.
5. Trying not to displace laying, accurately plant a head on the block.

6. Grease a carving and the bottom surfaces of heads of fixing bolts with pure impellent oil and screw fixture on the former places (do not forget to enclose under heads special washers. Tighten bolts by hand. Operating in strictly certain order, in three steps tighten bolts of fastening of a head of cylinders with demanded effort (see. Specifications).

All stages of a tightening should be duplicated twice, i.e., having tightened bolts with effort of the first stage, repeat procedure (tightening them with the same effort), after it pass to the second stage of a tightening, etc.

7. Operating in a similar manner, establish on the engine the second head of cylinders.
8. Installation of the remained components is made as it should be, the return to an order of their dismantle.
9. Do not forget to fill system of cooling and to replace the oil filter (see. Head of Control and routine maintenance).
10. Start the engine and check correctness of installation of a corner of an advancing of ignition (see. Head of Control and routine maintenance). Let's to the engine work within about five minutes on small turns for the purpose of air removal from assemblies of proof-readers of klapanny gaps. Make sure of serviceability of functioning of the unit.

The first five minutes after primary start the klapanny mechanism will work with the increased noise. If the noise level then does not decrease, it can indicate defect of one of proof-readers of klapanny gaps.
