To fix a problem in an old car, you just need to put it upside down. When working with modern cars, you need to depressurize the cooling system by loosening the pipe on the stove radiator fitting, ensuring the antifreeze is released along with the air.
Necessary
- - partner;
- - overpass;
- - clean cloth;
- - coolant;
- - key.
Instructions
Step 1
An airlock in the cooling system of the "iron horse" can cause many malfunctions, such as engine malfunction, seething, overheating of units, incorrect sensor readings, poor interior heating, thermostat failure and others. But before proceeding to eliminate this problem, it is necessary to exclude other, more serious reasons that could lead to the failure of the car's cooling system. We are talking about mechanical kinks and clogging of the system itself, scrolling, deformation or breakage of the impeller on the shaft, reduced pump performance, incomplete opening of the thermostat, and others.
Step 2
The process of removing the plug depends largely on the make of the vehicle. As a rule, there is a special screw plug on the branch pipe that leads to the stove. If you start the engine with the plug slightly unscrewed, then air will begin to escape from the system. But the problem is that it is difficult to do this on an old car. Therefore, you can try to remove the airlock through the highest point of the cooling system. To do this, the car must be installed on the overpass with its nose up and the engine must be turned on. After a while, the plug will come out through the radiator.
Step 3
To achieve this effect when working with a modern car, it is not enough just to install it on the overpass with its nose up. It is also necessary to break the sealing of the system. To do this, the outlet pipe on the stove radiator fitting is weakened until the pouring antifreeze does not contain air bubbles.
Step 4
You can go the other way: remove the plastic screen from the engine, release the clamp and remove any tube from the heating of the throttle assembly. Unscrew the cover of the expansion tank, cover the neck with a clean cloth and blow so that antifreeze flows from the disconnected tube. The final step is to quickly put the tube on the fitting and tighten the clamp. The plastic screen can then be replaced.
Step 5
You can try to remove the airlock using a universal method: for this, the car needs to be installed with its nose up, add coolant to the upper mark of the expansion tank, unscrew the screw on the radiator and turn on the stove in the cabin to the maximum. One person should get behind the wheel and periodically gas slightly, waiting for hot air to come out of the stove. The second is to drain the liquid until it stops bubbling. Only after that, the missing volume of liquid can be added to the tank and the lid can be screwed on.
