3.20. Service of the cooling system


Do not allow hit of antifreeze on open parts of the body and the painted surfaces of the car. Immediately wash away casual splashes a plentiful amount of water. Remember that antifreeze is extremely toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences (up to a lethal outcome). Never leave antifreeze stored in leaky closed container and immediately collect the cooling liquid spilled on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways utilization of the fulfilled cooling liquid consult with local authorities. In many regions of the world special points on different reception of working off are equipped. Do not merge old cooling liquid in the sewerage and on the earth at all!

Recently nontoxical grades of antifreeze were developed, however they also demand care in the address.

1. Regularly, according to the schedule of routine maintenance of the car (see the Section Schedule of Routine Maintenance of the Mitsubishi Galant/Mirage/Diamante Cars), the cooling system has to be emptied, washed out and be filled with fresh mix of antifreeze with water. Such service allows to prevent development of corrosion in a cooling path and considerably increases efficiency of functioning of system.
2. During service also the condition of all hoses of system and a cover of a jellied mouth of a radiator without fail has to be checked (see the Section Check of a Condition of Components of the Cooling System). Defective components are subject to replacement. Do not forget about precautionary measures which have to be observed at service of the cooling system (see the prevention at the beginning of the Section). Remember that the fulfilled cooling liquid is subject to utilization and should not merge in the sewerage at all.



1. Cock the parking brake and prop up wheels antiretractable boots, in case of need the car and establish to a poddomkratta it on props. It is necessary to start direct performing procedures of service only after full cooling of the engine, i.e., several hours later after end of a trip.
2. Uncover a broad tank / radiator.

In order to avoid receiving burns, do not uncover a radiator / a broad tank at all, without having waited for final cooling of the engine!

3. At the corresponding complete set of the car remove elements of protection of a case.
4. Get drain capacity under the drain gate of a radiator, open the gate and lower cooling liquid in the prepared capacity.

For the purpose of decrease in risk of casual damage of the gate manufactured of plastic, previously moisten it with the getting oil.

5. Having waited for depletion of a radiator, close the gate and take drain capacity from under the car. In case of need establish into place protection of a case.
6. Lower the car on the earth.



1. Having completely emptied the cooling system (see above), fill in in it special flushing liquid (as a last resort will approach soft water is usual).
2. Start the engine and wait until the top radiator hose becomes hot to the touch.
3. Having killed the engine, wait for its full cooling and again empty system.
4. Repeat the described procedure until the liquid merged from a radiator completely is not exempted from the maintenance of particles of a scum and will not gain absolute transparency.
5. Separately wash out a broad tank.
6. Having tightened the drain gate and, in case of need, having restored initial connection of all hoses, fill in fresh cooling liquid of the required structure in system, then remove from a cooling path air traffic jams (see further).

Gas station


1. Slowly fill in the fresh, made in proportions 50 x 50 mix of antifreeze with water in a radiator. Continue filling until the level of liquid does not rise to the lower cut of a jellied mouth. Add cooling liquid in a broad tank, having brought its level to the lower mark (FULL COLD) in a tank wall. Wait five minutes and double-check the level of cooling liquid in a radiator, in case of need make adjustment.
2. Without establishing a cover on a radiator, start the engine and warm up it before opening of the valve of the thermostat (liquid has to begin to circulate through a radiator, at the same time there will be a warming up of the top hose of the last).
3. Kill the engine and let's it cool down. Add a little more liquid in a radiator, having brought its level to the lower cut of a jellied mouth.
4. By tightening of the top hose of a radiator let out from it the air, in case of need add a little more cooling liquid. Establish into place a radiator cover.
5. Transfer the handle of management of system of heating of salon to the maximum heating, turn on the heater fan on the maximum speed.
6. Start the engine, warm up it up to the normal working temperature and check system for existence of signs of leaks.
7. Overheating of the unit demonstrates existence in a cooling path of air traffic jams. Kill the engine and let's it cool down, - air has to leave a path automatically. Repeating the procedure, achieve the required temperature condition of the working engine.
8. Double-check the level of cooling liquid in a broad tank, in case of need make the corresponding adjustment.
