| 1. 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. |
| 2. 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. |
| 3. 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 (see subsection 4.2). If the level of cooling liquid is lower than edge of a jellied mouth, then add mix of water and antifreeze (see subsection 2.5.1.2). |
|
4. 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. |
|
5. Always check existence on hoses of traces of a podgoraniye or wear which can be the cause of unforeseen refusal and expensive repair. Softness of a hose indicates destruction of its material, products of destruction can cause pollution of the cooling system and blocking of internal channels of a radiator. |
|
6. The hardened hose can burst at any time, the additional inhaling of a collar will not lead to improvement of consolidation and to the dribble termination. |
|
7. Swelling of a hose or treatment of edges of a hose oil indicates a possibility of destruction of a hose with dangerous consequences, check existence of cracks and gaps for what press a hose. |
| 8. 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. |
| 9. 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. |
| 10. 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. |
