1. Turn a radiator stopper to the left against the stop. If hissing (that testifies to residual pressure) is heard, a stopper do not get before complete dumping of pressure. Now press a stopper a palm, tighten to the left and get a stopper. Carefully wash out a stopper pure water, wipe a radiator mouth pure rags. Remove all traces of corrosion. Cooling liquid in a radiator should be transparent. If cooling liquid is painted in color of a rust, system it is necessary to wash out and replace liquid. If level of cooling liquid is lower than edge of a jellied mouth, add a water and antifreeze mix
(see subsection 2.5.2). |
2. Check 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 if a hose to press. Irrespective of a condition of hoses it is recommended to change them each two years. |
3. Be convinced of durability of all connections. Leakage of cooling liquid can be found on a raid of white or brown color near a place of violation of tightness. If hoses are fixed by wire collars, it is necessary to replace the last with collars with screw fastening. |
4. With the compressed air or a brush remove from intercostal spaces of a radiator and the conditioner condenser the remains of insects, plants and extraneous subjects, thus do not injure a radiator or condenser edge. Be careful, as edges have sharp edges. |
