1. Turn a radiator stopper to the left against the stop. If hissing (that testifies to residual pressure) a stopper do not get before full dump of pressure is heard. Now press a stopper a palm, tighten to the left and get a stopper. Carefully wash out a stopper pure water, wipe a mouth of a radiator pure rags. Remove all traces of corrosion. The cooling liquid in a radiator should be transparent. If the cooling liquid is painted in colour of a rust system it is necessary to wash out and replace a liquid. If level of a cooling liquid below edge of a jellied mouth add a water and antifreeze mix (see subsection 2.5.2). |
2. Check up a condition of the top and bottom hoses of a radiator and heater hoses. Examine hoses on all length, at detection of swelling of hoses, cracks and the general deterioration of a condition a hose replace. Cracks are easily found out if a hose to press. Irrespective of a condition of their hoses it is recommended to change each two years. |
3. Be convinced of durability of all connections. Leak of a cooling liquid can be found out on a touch of white or brown colour near to a place of infringement of tightness. If hoses are fixed by wire collars it is necessary to replace the last with collars with screw fastening. |
4. Compressed air or a brush remove from intercostal spaces of a radiator and the condenser of the conditioner the rests of insects, plants and extraneous subjects, thus do not damage a radiator or condenser edge. Be careful, as edges have sharp edges. |
