Why clog radiator stove
Clogging the radiator - it is one of the most common causes poor performance of the interior heater. Most often this is due to poor coolant mixing two different antifreeze composition, or using water.
All this leads to the formation of plaque on the walls from the inside. Dirt tightly clogs the already thin tube radiator with zavihriteljami, disrupting circulation, and about any heating can be no question.
How to understand that the problem of blockages in
Check whether the stove is clogged radiator is really quite simple. We need to find two thin pipe going into the cabin through the engine compartment bulkhead, and touch them. If one of them is hot and the other barely warm or cold, it is clogged.
In some cases, the heater will blow cold air will be hot even if the two pipe. This may indicate the following: in all culled so much that the heated antifreeze gets in the radiator tank and passing cell, then leaves it, not having time to give heat.
What to do
The standard solution to this problem - replacement radiator a new one. It is recommend to service station. There will have to fork, as to the price of a new radiator is added cost of works, which is 2-3 times more expensive than the actual spare. In modern cars to get to the radiator is not easy: it is necessary to remove the lining and the dashboard, loosen the pipe air conditioner, and then refuel it.
The second option - washing directly on the machine. In this case, everything is much simpler and does not need to shoot anything. Suffice it to detach tubes extending to the heater, instead connect the pump with hoses through the radiator and drive wash solution.
How effective washing heating cooler
Radiator cleaning is much easier, faster, and definitely cheaper replacement, but this procedure, there are also disadvantages. Rinsing is not a panacea, the chances of success of about 50 to 50. In advanced cases, the effect is sometimes not.
Again, on older machines radiator may leak only due to the fact that washed away sediments that covered the holes in the tubes. Well, there is always the chance of re-entering the dirt from the cooling system in the washed stove.
And yet, before changing the radiator, many car owners prefer to wash it first.
How to wash the stove heat sink without removing it
1. Prepare everything you need
Almost everything that you will need to clean up, you can find in any garage, to purchase in the near auto and household store.
- 150-200 g of citric acid;
- bucket of 8-10 liters;
- capacity to drain antifreeze;
- hose length of about 3 m;
- collars;
- wire;
- mesh, gauze or nylon;
- water;
- antifreeze for topping up;
- a pump for pumping;
- boiler or stove;
- spanners;
- screwdriver.
2. Get familiar with the process of the essence
The principle of washing heating cooler is as follows. The heater is disconnected from the cooling system and connected thereto pump with hoses. In a separate container dissolve chemicals and preheated, and then via pump wash liquid is circulated through the radiator. This makes it possible to dissolve and wash all the accumulated dirt.
To again debris does not enter into, its output was collected and removed by the filter gauze impromptu or old nylon tights. Then radiator is rinsed with pure water and regular water hoses are installed in place.
3. Remove the battery terminals
When removing the radiator pipes may have to disconnect some wiring connectors. Therefore, to avoid management errors is better to disconnect the vehicle's electrical system, removing the battery terminals. Minus first, and then - the plus.
Make sure your heater is set at maximum heating. If the control is carried out with a crane, in the closed position it will block and prevent fluid flow washing.
4. Drain the coolant
The heater is filled with antifreeze. So that the fluid does not leak on the floor, when you remove the pipes, it must be drained into a prepared container through the tube on the main radiator.
Since the oven - not the lowest point of the system, you can not pour all the antifreeze, but only part. With adequate accuracy it will be done directly through the pipes during removal time.
5. Remove the tubes from heating cooler
Locate and remove the two thin tube which goes to the salon. They are located between the engine and the partition wall of the engine compartment. They are usually easy to spot, but if you can not or are afraid to make a mistake - check the documentation for the car or look on the Internet.
Then, simply loosen the hold-down clamps and remove the tube, turning from side to side. Be prepared for the fact that flow out of them a little more coolant.
6. Connect hoses and pump
Take any suitable diameter hoses (typically diameter 16 or 18 mm), put on the heater tube and lock the clamps. The free end of a hose connected to the pump, the second wrap gauze and dip into a container for rinsing. Also put on a small section of hose pump for collecting liquid.
It should get something like this scheme, as in the photo. As the pump is most convenient to use an additional pump heater on "Gazelle", which is sold cheaply in any auto. Of the other options - the circulation pump of the boiler or holiday pump for irrigation.
7. Prepare and preheat wash
For cleaning of dirt and scum using specialized tools, reagents for the purification of sewage, caustic soda and plain citric acid. Last is the safest and at the same time not less effective.
Take 5-6 liters of water and 150-200 g of conventional pour citric acid, stir well and heat the solution. Can be heated via reboiler, on an electric or gas burner. For maximum effect, the water temperature should be at least 75 ° C, preferably - close to boiling.
8. Start the pump
Fill the pump intake hose solution, quickly dip the tube into the tank and turn on the pump is energized. After this washing process begins: the fluid will circulate in the bucket and merging again acting THEREOF radiator.
If the heater is packed with too much water will first flow from it a weak trickle. Then, as the impact pressure of the solution increases.
Full flushing takes from one to several hours, depending on the condition of the radiator. If a strong pollution, you may have to change to a fresh solution.
Most importantly, every 15-20 minutes to change the direction of circulation, swapped hoses at the pump. This will help clean up the maximum amount of dirt.
When the output from the radiator good flow goes relatively clean water, flushing can be considered completed.
9. Wash water radiator
Upon completion of the process to wash off the residues of citric acid, so that it is not later mixed with the coolant in the system.
It is sufficient to drive the radiator several liters of distilled water. Drain the excess solution, rinse the container and then fill with water and run the pump as in the previous step.
10. pour antifreeze
After all the manipulations a jet of air to remove excess water from the radiator and disconnect the flushing hose. Set in their place staff and secure clamps.
Once again, check everything and make sure that the plugs are closed. Next, pour the antifreeze which poured earlier, and, if necessary, add a new one - to the level in the expansion tank was normal.
11. Remove air pockets
When removing the flushing nozzles and the cooling system are inevitably formed air pockets. Over time, they will come themselves, but because of them heater can operate intermittently, so it's better to get rid of the air at once.
To do this, you need to stop by the pier or steep hill to pick up car radiator as high as possible, and some times a good push on the gas. At this point it will be heard gurgling inside the heater, which will stop after slugging.
12. Check heater operation
Good warm up the engine and evaluate the results. If the problem really was clogged radiator and you've done everything correctly, the effect will be pleasantly surprised. Oven heat will be like new, and the heat from the ducts will begin to go within a few minutes after the engine startup.
