18. Disconnect an air pipe from a head of the block of cylinders (see rice. An arrangement of an air pipe on a head of the block of cylinders).
19. Unscrew an arm of fastening of the air valve and remove it together with a pipe from the engine (see rice. Arrangement of an arm of fastening of the air valve).
20. Take off pressure in fuel system and unscrew the giving and returnable fuel-supply lines (see rice. Unscrewing of a fuel-supply line from pressure regulator on the engine of 3,0 l).
21. Unscrew a bolt, pipes fixing an arm for the probe of measurement of level of oil. Take the probe and remove a pipe from the block of cylinders (see rice. Unscrewing of an arm of fastening of a pipe for the probe of measurement of level of oil).
22. Disconnect an accelerator cable from the lever of a butterfly valve.
23. On models with the automatic transmission disconnect a cable of management of pressure from draft of a butterfly valve.
24. On models with the automatic transmission, unscrew bolts of fastening of a pipe of the probe of measurement of level of oil in the transmission from a back part of a head of the block of cylinders (see rice. Unscrewing of a bolt of fastening of a pipe for the probe of measurement of level of oil in the automatic transmission).
25. Unscrew and remove two arms of support of an inlet collector (see rice. Arrangement of bolts of fastening of an arm of support of an inlet collector).
26. Remove a clip of fastening of a vacuum hose and a plait of wires from a reverse side of an inlet collector.
27. Weaken a collar and remove a hose of ventilation of a case from a casing of a sapun under an inlet collector (see rice. Arrangement of a hose of ventilation of a case of the engine).
28. Weaken a collar and remove a hose of supply of cooling liquid from a cranked branch pipe on the forward party of the engine.
29. Check that all hoses and электричес sockets are disconnected by Kia from a head of the block of cylinders.

31. Screw a forward eye for raising of the engine on a head of the block of cylinders.
32. Using the load-lifting mechanism, remove a head of the block of cylinders (see rice. Removal of a head of the block of cylinders from the engine).
33. Remove laying of a head of the block of cylinders.

Preparation for installation


PERFORMANCE ORDER
1. The interfaced surfaces of a head and the block of cylinders of the engine need to be cleared carefully of the remains of laying and a deposit, using a plastic or wooden scraper. It is also necessary to clear the top parts of pistons. When cleaning exclude a possibility of hit of products of cleaning to oil canals of the cooling system. Carefully clear the internal surfaces of cylinders.
2. Check the surfaces of interface of a head and the block of cylinders of the engine for existence of defects. Insignificant damages are eliminated with machining. Also, using металличес I forge a ruler and the probe, check planeness of the interfaced surfaces.
3. Clear openings under bolts in the block. Screwing up of a bolt in the opening filled with oil can break off the block because of hydraulic pressure.
4. Measure length of bolts of fastening of a head of the block of cylinders (see rice. Preparation for installation). If length of a bolt exceeds admissible limits, replace bolts in a set.

Installation

Sequence of tightening of bolts of fastening of a head of the block of cylinders of the 6-cylinder DOHC engine

PERFORMANCE ORDER
1. Check that adjusting tags of cranked and distributive shaft are combined with indexes.
2. Establish laying of a head of the block of cylinders on the directing pins of the block of cylinders.
3. Establish two bolts of back fastening of a head of the block of cylinders.
4. Using the load-lifting mechanism, install a head of the block of cylinders on the engine.
5. Unscrew bolts and remove a forward eye for raising of the engine from a head of the block of cylinders.
6. Grease bolts of fastening of a head of the block of cylinders with engine oil and, being careful, insert them into nests. Screw up bolts of fastening of a head by hand.
7. In the sequence shown in the drawing Sequence of Tightening of Bolts of Fastening of a Head of the Block of Cylinders of the 6-cylinder DOHC Engine tighten bolts of fastening of a head of the block of cylinders in several stages.
