At replacement of cooling liquid it is necessary to remember that its concentration and quality not only prevents liquid freezing, but also lifts boiling temperature, and also protects system from corrosion and scaling on walls of channels. For this reason even for the summer is not admissible to fill system of cooling with usual fresh water. Correctly picked up cooling liquid will prolong service life of all system of cooling.

PREVENTION Replacement of cooling liquid make on the cold engine

Replacement of cooling liquid carry out in the following order:

Fig. 4.1. System of cooling of the SOHC engine: 1–radiator; 2–thermostat; 3–connecting branch pipe; 4–broad tank; 5–top cover;    6–air inlet; 7–fan (EZ) arm; 8–fan arm (RV, RP); 9–arm of fans; 10-additional fan; 11-driving belt; 12-electric fan

– unscrew a cover of a broad tank 4 (see fig. 4.1 );

– establish capacity of the corresponding volume for collecting cooling liquid under a radiator;

on the car equipped with the amplifier of a steering, remove a driving belt of the pump of the amplifier of the steering mechanism from a pump pulley, weaken bolts of fastening and turn a pump arm up, for simplification of access to hoses of the thermostat and the pump of system of cooling;

– disconnect bottom and bypass a hose from the thermostat 2 and the case of the water pump on the left side of the engine or unscrew a cover of the thermostat and remove the thermostat;

– merge cooling liquid in the prepared capacity.

– repeatedly connect all hoses and establish the thermostat;

– do not connect the pump of the amplifier of a steering, an arm and a driving belt until fill system of cooling with new cooling liquid;

– slowly fill in cooling liquid in a broad tank to level slightly below a label "MOVE";

– check tightness of the bottom and bypass hoses and connection of the thermostat with the pump of system of cooling;

– establish an arm of the pump of the amplifier of a steering and a driving belt;

– establish into place a cover of a broad tank;

– start the engine and let's to it work in a mode of the accelerated turns of idling, before turning on of the electric fan of cooling of a radiator;

– switch off the engine and check level of cooling liquid in a broad tank. At the normal working temperature, cooling liquid should be about a label "MOVE";

– after the engine will cool down repeatedly check level of cooling liquid.
