GENERAL INFORMATION

Prevention

The final valves established on the engine of 20 XEJ and С20 XE (DOHC) contain sodium which is used for increase in heatreturn. Sodium is a highly active metal which can ignite or blow up at contact to water or water vapor.


Replacement of a sealing ring of a casing of the thermostat on the engine of 2,0 l

Arrangement of the unilateral valve of pressure of oil (1) and stopper (2) on the engine of 2,0 l

PERFORMANCE ORDER
1. Remove the remains of old laying from a head of the block of cylinders.
2. Clear a deposit from combustion chambers, then wash up a head in the corresponding solvent.
3. Clear of carbonaceous deposits of the valve, it is possible even with application of a wire brush.
4. Carefully examine a head of the block of cylinders on existence of cracks and other damages. In the presence of cracks the head is subject to replacement.
5. Using a metal ruler and щуп, check planeness of an interfaced surface of a head of the block of cylinders. At not planeness more than 0,1 mm it is necessary перешлифовать a head, thus its height should correspond to requirements.
6. Check a condition of saddles of valves. If they are burned, worn-out or have defects, it is necessary to replace them. If wear of a saddle of the valve is insignificant, they are necessary for grinding in. Check directing plugs of valves on wear, inserting into them a core of the valve and moving it aside. Moving should be insignificant. If moving is excessive, take the valve and measure diameter of a core of the valve. If necessary replace the valve. If the core of the valve is not worn-out, means, the directing plug which it is necessary to replace is worn-out. Replacement of directing plugs of valves should be made at service station.
7. If saddles of valves have to be перешлифованы, this operation is necessary for executing after installation of new directing valves.
8. On engines 1,8 and 2,0 of l replace the sealing ring located between a head of the block of cylinders and a casing of the thermostat (see fig. Replacement of a sealing ring of a casing of the thermostat on the engine of 2,0 l).
9. For replacement of the unilateral valve of pressure of oil (1) in a head of the block of cylinders unscrew a round stopper (2) and take the valve from a head of the block of cylinders. Establish the new valve on a place and screw up a stopper (see fig. An arrangement of the unilateral valve of pressure of oil (1) and a stopper (2) on the engine of 2,0 l).
