Mitsubishi Galant

1. The wide spectrum of engine failures is connected with infringement of functioning of system of cooling. On the models equipped АТ, the given system provides also cooling ATF, supporting thereby optimum conditions for transmission work.
2. Check of a condition of components of system of cooling should be made after full cooling of the power unit (not less than in three hours after an engine stop).

At all do not remove a cover of a jellied mouth of a radiator at the hot engine!

3. Remove a cover from a radiator or a broad tank for what at first turn it to the left to the first emphasis. If the hissing specifying in superfluous pressure in system is heard, wait its terminations, then press a cover a palm downwards and continue to turn to the left before full clearing. Carefully wash out a cover from within and outside of pure water. Wipe a jellied mouth of a radiator. From cleared surfaces all traces of corrosion should be completely removed. The cooling liquid being in system should be concerning transparent. If the liquid is painted in colour of a rust, the system should be washed out and filled by a fresh mix (see Has undressed Service of system of cooling). If liquid level does not reach top, add in a radiator/tank of a little more mix of demanded structure.
4. Attentively examine top and bottom радиаторные hoses, and also hoses of system of heating of the salon, having smaller diameter and located between the power unit and a partition of an impellent compartment. Check hoses on all their length and in case of revealing of cracks, swellings and signs of ageing of a material make replacement of defective components. Small cracks usually to make out at сжимании a hose easier. Without dependence from a condition it is necessary to change hoses approximately time in two years.
5. Check up reliability of fastening of all hoses on the unions/branch pipes. Leaks of a cooling liquid usually are shown in a kind потеков rusty or white colour on surfaces surrounding their source. If hoses are fixed on unions/branch pipes by collars of braided type, it will be reasonable to replace the last more reliable worm or screw.
6. By blowing off by the compressed air, or by means of a soft brush, remove from backlashes between plates of the heat exchanger of a radiator old leaves, remains of insects and other dust. Try not to damage soft plates of the heat exchanger and not to cut fingers about their sharp edges.
7. Every second check, and also at first signs of infringement of functioning of system of cooling make check of a cover of a radiator by pressure (see further). If near at hand there will be no suitable equipment, address for the help on a car repair shop.
8. Having removed a cover from a radiator or a broad tank, by means of a corresponding transitive nozzle connect to system the manual pump equipped with a manometre.

9. Working as the pump handle, lift pressure in system to the maximum value of the indication of the manometre connected to the pump.

10. During some time observe manometre indications, - if pressure in system falls, hence, leak takes place. Revealing of a source of leak is made during repeated careful survey of all components охладительного a path (once again pump up pressure).

11. If during visual survey to reveal a leak source it is not possible, again lift pressure to a maximum and leave system under pressure upon some time. After nearby 30 minutes check up the manometre indication, - if it has fallen less than to 20 %, it is possible to consider a system condition satisfactory, otherwise it is necessary to address for the help to experts of car-care centre.
12. One more of the reasons of losses of a cooling liquid are its internal leaks. A similar sort of leak are usually connected with infringement of tightness of linings of heads of cylinders or occurrence of cracks in a body of the block and lead to hit of a cooling liquid in engine oil and chambers of combustion of the engine. Oil thus begins эмульгировать, accepting a dairy-shaped consistence, the exhaust smoke at the moment of engine start appears the sated water steam giving to it dense white colour. One more of signs of presence of internal leaks of a cooling liquid is formation on electrodes of spark plugs of a touch of greenish or white colour, - by serial survey of candles it is possible to reveal the cylinder supposing leak.
