Cooling liquid made on the basis of ethylene glycol, used in the cooling system of internal combustion engines and called antifreeze brand "Tosol 40A" (translated from English - antifreeze liquid), in addition to its main function aimed at cooling a running engine, protects the engine from corrosion, thanks to special additives. This significantly increases the service life of the vehicle.
It is necessary
Screwdriver, 13 mm wrench, antifreeze drain container
Instructions
Step 1
The use of antifreeze in the conditions of year-round operation of the car eventually leads to the loss of its properties. The quality of the coolant is determined by simply measuring the density of the antifreeze. When the density drops below acceptable standards, the coolant in the cooling system must be replaced with new antifreeze.
Step 2
Due to the fact that the specified liquid is very poisonous, then when carrying out its replacement in the engine, it is required to observe all precautions when working with poisonous chemical compounds.
Step 3
To drain the old antifreeze, you must remove the plug on the expansion tank.
Step 4
In the lower part of the radiator, as a rule, on the right side, a rubber or silicone tube is put on the hole for draining the coolant from the radiator, which at one end is lowered into a container designed to drain the spent fluid. And then the drain plug is opened with a screwdriver.
Step 5
After that, the tank for draining the antifreeze is installed from below under the plug located at the lowest point of the engine cooling jacket. Then the plug is unscrewed with a wrench, and the old coolant is drained from the engine.
Step 6
After screwing the plugs into place through the expansion tank, the engine cooling system is filled with fresh antifreeze.
