2.1.8.3. Cooling liquid
Prevention
Wait until the engine cools down before the beginning a slitiya. You watch that cooling liquid with antifreeze did not get on skin or the painted body surface.
Malfunction of the cooling system is the reason of many characteristic engine failures. On cars with automatic transmission the condition of the cooling system which cools also transmission liquid significantly influences durability and non-failure operation of work of transmission.
Replacement
PERFORMANCE ORDER |
1. The cooling system is checked on the cold engine. Check system to a trip or not less than 3 hours later after an engine stop. |
2. Turn a radiator stopper to the left against the stop. If hissing (that testifies to residual pressure in the cooling system), then do not reach a stopper full dumping of pressure is heard. Now press a stopper a palm, tighten to the left and get a stopper. Carefully wash out a stopper clear water, wipe a radiator mouth with pure rags. Remove all traces of corrosion. Cooling liquid in a radiator has to be transparent. If cooling liquid is painted in color of a rust, then system it is necessary to wash out and replace liquid. If the level of cooling liquid is lower than edge of a jellied mouth, then add mix of water and antifreeze. |
3. Check a condition of the top and lower hoses of a radiator and hoses of a heater which conduct from the engine to a wall of a motor compartment. Examine hoses on all length, at detection of swelling of hoses, cracks and the general deterioration in a state replace a hose. Cracks easily are found if a hose to press. Irrespective of a condition of hoses it is recommended to change them each two years. |
4. Be convinced of durability of all connections. Leak of cooling liquid can be found on a raid of white or brown color near the place of violation of tightness. If hoses are fixed by wire collars, then the last should be replaced with collars with screw fastening. |
5. Remove with compressed air or a brush from intercostal spaces of a radiator and the condenser of the conditioner the remains of insects, plants and foreign objects, at the same time do not injure an edge of a radiator or the condenser. Be careful as edges have sharp edges. |
6. At the subsequent check or in case of abnormal operation of the cooling system check a condition of a stopper of a radiator and pressure in system. In the absence of the manometer it is necessary to address to service of car service where this service will be rendered for the minimum payment. |
7. Remove a cap of a broad tank. |
8. Remove a protective guard from below of the engine if it is necessary, and install a container for collecting cooling liquid. |
|
9. Turn off a drain cap (shooter) and merge cooling liquid. |
10. Establish a cap into place. |
|
Washing of the cooling system
If the cooling system got littered, it needs to be washed out.
Washing of a radiator
PERFORMANCE ORDER |
1. Disconnect all hoses from a radiator. |
2. Insert a water hose into the top branch pipe of a radiator and wash out it clear water or the clearing solution. |
|
Washing of the engine
PERFORMANCE ORDER |
1. Remove the thermostat and temporarily establish a thermostat cover into place. Connect the top hose of a radiator. |
2. Insert a water hose into the top hose of a radiator and wash out the engine clear water. |
|
Gulf of cooling liquid
PERFORMANCE ORDER |
1. Check a condition of all a hose and cooling system collars. |
|
2. Remove a cap of a broad tank and slowly fill in cooling liquid to the mark KALT/COLD in a tank. |
3. Twirl a tank cap. |
4. Start the engine and warm up it up to the normal working temperature. |
5. Kill the engine, wait until it cools down, and check the level of cooling liquid. |
|
Cooling liquid with the content of antifreeze
Regularly replace cooling liquid with the content of antifreeze as over time antifreeze loses the anticorrosive qualities.
