The better to glue the cooling radiator How to glue the cooling radiator - repair methods

Every car has a cooling system. Without it, the vehicle would be very tight due to constant overheating.

This system is a complex mechanism that has a multi-stage structure, and during the execution of work, the cooling system is subjected to high pressure and temperature.

For this and other reasons, the radiator is capable of leaking, and such a situation will not only add discomfort to the lives of drivers, but will also create a danger to internal car structures. Everyone should know how to glue the cooling radiator so that when such a problem arises, they can solve it.

What is the danger of constant leakage of coolant?

If the cooling radiator starts to leak, you should definitely know what to do or to which craftsmen to contact to fix a similar problem. Constant leakage can lead to aggressive and even the most dangerous situations:

  • Engine overheating and its future failure.
  • Modifications to the configuration of the cooling system and deterioration of the integrity of the material used as a gasket
  • Engine seizure, which can lead to expensive and time-consuming repairs.
  • Thermal burns, which may appear when cracks in the radiator break and the heated liquid flows out in the form of fountains.

Why a radiator is required and why its leaks are so dangerous, you have learned, and now it is worth moving on to the main question - to consider methods of eliminating leaks and returning the sealing to the cooling system.


How to quickly remove a leak

First, you should determine the location of the leaks, and this can be done in several ways:

  1. The better to glue the cooling radiator Carefully, and also in detail, you should inspect the line through which the fluid will move. There will be a wet spot at the site of the leaks, and this method does not always give positive results, for example, if there are microcracks.
  2. The compressor makes it possible to quickly find all problem areas that need repair work. On the radiator, close all the exits, leave only one, and fill the system with water and supply air through the compressor. A pressure of 1 atm will be quite enough, and a cooling radiator will just flow in places with water droplets.

    This method does not require demolition work, which is appreciated by most drivers.

  3. If the radiator begins to leak in the car, but there are no wet spots on the structure and the compressor is not at hand either, then it should be dismantled. The structure should be placed in a container of water, and a bathroom is best suited, and air is also supplied. There are problems at the site of the formation of bubbles.

Leaks often appear even on the road, far from home and even a settlement.

It will not be possible to continue driving, and it is not worth it, it is dangerous for drivers and cars. We will tell you how you can repair a car radiator with your own hands using available tools.

  1. A piece of an old car camera and a clamp makes it possible to temporarily close the leak and drive to the nearest settlement or car accessories store. You can close the leak with rubber, and squeeze it with a clamp.
  2. Pliers are definitely in every driver's travel kit.

    They are required to plug a damaged tube. There should be no more than five such pipes, and otherwise, the cooling will be greatly reduced and the system will not cope with the task assigned to it.

  3. Sealant is an extremely useful tool that can help out at the most unexpected moment. Sealants can be different and the principle of application can be significantly different. Instructions for use are always indicated on the packaging, and study it to follow the recommendations of the manufacturers.

Let's consider other ways of fixing.

What to do if the damage is serious

How to glue the plastic cooling radiator, consider further. The methods described above can help to fix small defects and for a short time. All the same, you will need to engage in major repairs, which makes it possible to increase the service life of parts. In addition, sealing the leak must be thorough so that there are no unpleasant situations on the road.

Bonding of plastic elements of car radiators

Most cars are equipped with plastic radiators. They are made of a special compound that is highly durable and resistant to workloads. The repair of such parts has some peculiarities, and, if you do not take them into account, that the adhesive composition will not be able to adhere to the treated surface. And yet we have found several methods that will make it possible to glue the heating radiators in the car and provide a high quality result.

  1. Soldering is used on heat-resistant plastic, and the simplest soldering iron can be used.

  2. "Cold welding" is a very successful way to eliminate leaks in a plastic housing. If all work is done correctly, in accordance with the manufacturer's recommendations, then there will never be a leak in such a place. "Cold weld" will firmly bond to surfaces and create a high strength bond that is free from vibration, temperature changes and pressure.
  3. Adhesive and sealant (2 in 1) can even repair small cracks. In the case of huge defects, a different method is required, and in any case, this method will be a temporary measure.

  4. Glue-adhesive 3M DP8005 two-component type demonstrates high efficiency and can work even with extremely difficult types of plastic.The treated area will not be the cause of leakage, because the seam is not destroyed by external factors and working type loads. The only drawback is the high cost, and it fluctuates around 1600 rubles.
  5. Hosch welding has been specially designed for working with plastic radiators, and the result will be durable and reliable, and the seam will be designed for high workloads.

We figured out how to seal a plastic radiator for cooling, and now you can proceed to the practical guides.

Depending on the chosen method, the work plan will differ, but in general terms it will look like this:

  • Prepare the materials and tools that are needed in further work. The material for gluing, usually these are two-component type compositions, because they make it possible to achieve a high degree of strength, and also sandpaper for treating leaks, gloves, a degreaser (acetone, as a rule) and cotton swabs.
  • Places with leaks and the surrounding area are thoroughly cleaned and then degreased.
  • Prepare the adhesives according to the manufacturer's advice.
  • Apply the prepared compound to the work area, and if the crack is large, then the adhesive will be applied in several stages until a tightness is achieved.

  • Wait for the specified time, which it takes for the mixture to harden, and this usually takes 1/4 hour. In the case of epoxy resin, you need to wait a day in order to be a significant drawback of such a material.
  • Stiffened surface should be sanded with fine-grained paper.

Now you know how to glue a leaking cooling radiator, we will consider the aluminum version of the tank further. Agree, there is nothing complicated, and therefore it is not at all necessary to contact a specialist with a similar problem.

Soldering aluminum radiators

Do not rush to grab the soldering iron right away - this will all succeed. Before, you should study the scale of the tragedy and choose the most acceptable option for repair work.

  • The place with a small defect can only be filled with solder.
  • A large sample will need to be covered with a patch or even soldered along all contours.

Hereinafter, it will be described in detail how to seal the radiators.

If you follow these instructions, even a person without the necessary experience will definitely succeed.

  1. The better to glue the cooling radiator Disassemble the device, drain the liquid from it, and disconnect the pipes, bolts and remove the assemblies.
  2. Remove dirt, dust and dry at the leak.
  3. It is important to apply rosin to a clean and dry surface, but it is better to use soldering acid.
  4. For aluminum type radiators, it is important to use reactive flux or aluminum solder.

    This is due to an oxide film that forms instantly. She can disrupt the entire repair process.

  5. A leak may appear on the pipe - this situation is not uncommon, and in this case it is necessary to warm up the soldering point and remove the pipe. Next, solder or replace the tube with a new one if the damage is large.
  6. The pipe is not always easily accessible with a soldering iron.

    In this case, you need to insert the heated rod inside the damaged tube, and the temperature will make the solder soft, which will make it possible to remove the tube without problems.

Since we are talking about the soldering of radiators, then recommendations should be made regarding such a repair of structures made of brass and copper. To repair these parts, a special soldering iron should be used, which is designed to work with such building materials. The power of such a tool must necessarily be more than 250 W, and the work will be done according to this scheme - the surface still needs to be cleaned and dried, it is important to warm up the material, apply the rosin as evenly as possible, and then apply the solder in an even layer too.

Is it always possible to repair a radiator?

It won't always be advisable to repair a radiator, and in special cases it will be easier and even cheaper to install a new one .

.. But how to understand that this is exactly the situation in front of you and not waste time on recovery? We will help you understand everything.

  1. Leaks located at the junction of the radiator and the plastic pipe cannot be repaired. Leaks can be removed, but only as a temporary effect, and it is best to use epoxy sealant or glue in such a situation.

  2. Nothing can be saved from rust, which became the root cause of depressurization. You should not waste time, money and materials on such a radiator. It will be subject to recycling.
  3. Structural breakdowns due to an accident often cannot be removed, and even if there is a chance of success, the cost of repairs will be high.

All leaks begin with small cracks, and it will be much faster and easier to fix it.

With regular repair work, the radiator can last for a long time and cope well with the duties. Remember that not all defects can be eliminated, and in some extremely advanced cases, parts will need to be replaced.
