With the onset of cold weather, many VAZ car owners have problems with the operation of the heating system. In this case, the stove either does not heat well, or does not heat at all, and cold air blows from it. An air lock in the heating system may be a possible cause of the malfunction.
It is necessary
- - instructions for repairing a VAZ car;
- - coolant: antifreeze or antifreeze.
Instructions
Step 1
To make sure that the airlock is the cause of the stove malfunction, try the stove radiator - in this case, it should be hot. If this is not the case, look for the breakdown elsewhere.
Step 2
After making sure that there is air in the heating system, try to drive your front wheels onto any hill, hill or overpass and let the engine idle at medium speed for several minutes.
Step 3
If the previous method did not give results, disconnect the branch pipe from the throttle assembly, which goes to the return. Pour antifreeze or antifreeze into the tank. If the coolant immediately ran from the throttle unit branch pipe fitting, then plug the fitting and hold until the antifreeze runs from the hose.
Step 4
If the liquid does not go immediately, start the VAZ and close the hose with your finger. Wait until the cooler runs out of the pipe. After the work done, put the pipe back on and loop. Warm up the internal combustion engine to operating temperatures and check the stove.
Step 5
After filling the system, firmly press on all hoses, and screw the expansion tank cap as tightly as possible. This will prevent coolant that has expanded after heating from leaking out of the holes left and air bubbles from entering the expansion tank.
