- Dry mustard powder, polymer sealant, special soldering iron, solder, a "cold welding".
Find the place of leakage of antifreeze from a car radiator. If the hole is small, it is easier just patch them with the help of special additives that are backfilled or filled directly into the cooling system through the reservoir or expander through the neck of the radiator.
Dissolve some powder dry mustard in the antifreeze and pour the mixture into the cooling system of the car. Start the engine. When the antifreeze heats up, the mustard steamed and reduce or even completely seal small leaks.
Use modern polymer sealants. Pour in the polymerizing medium and warm up the motor. The heated sealant is exposed to air will turn into a solid film in place of the flow of antifreeze. This method is suitable for small size holes, not more than 2 mm2. Such sealant high cohesion (adhesion of particles), so the tubes of the radiator will not be affected.
If the holes in the radiator are large and sealant powerless, conduct more extensive repairs. Drain the engine coolant. Copper radiator crack sealed using a special powerful soldering iron and solder.
If the radiator is aluminum, use the "cold welding". This is a special two-component adhesive-sealant based on epoxy. In appearance and structure, it resembles clay. Consists of two parts, which prior to use need to mix.
Try to degrease and dry the place of sealing. Tape the crack carefully and thoroughly, observing technology. Give "cold welding" to harden and seize, before you start the car.
Prepare yourself for the fact that such repairs are only temporary. Be sure to watch the coolant level in the reservoir of the expander. If there continue to be leakage of antifreeze, add coolant before each exit of the Parking lot.
Replace leaking radiator new at the first opportunity. At the same time change to new hoses and clamps cooling system of the machine.
Unfortunately, the mustard because of the low level of adhesion of its particles to each other scored tubes of the radiator, and then they fail. Therefore, it is recommended to use for quick repairs on the way.
Advice 2: How to make a hole in the belt
Each strap has numerous holes so that any person could adjust its length to fit your own waist. But sometimes you have to do extra holes in the strapthat will be useful when you lost or too recovered. This saves money on buying a new belt and leaves you in the company of your favorite things.
You will need
- Pen, wooden Board, hammer, nail, rivet, knife, Shoe, toothpick.
Attach the belt to the waist and define the place on it where necessary to make a hole. Mark this area with a pen, making a small point parallel to and at equal distance from the other holes in the strap.
Put the belt on a wooden Board outer side up. Put to the designated place the nail and hold it with two fingers perpendicular to the Board head up.
Gently tap the nail with a hammer, reinforcing each successive blow, until the leg of the nail completely penetrate the belt. Remove the nail from the hole.
If a leather belt – hole ready. If the belt is made of a different material and all the holes in it are processed with rivets, and have this new opening is also decorate with rivet. Use a sharp knife and a hammer to smooth the edges of the rivet.
Leather belt (no studs) in a new puncture site should be treated with a colorless Shoe Polish. Use a toothpick or cotton swab to drop into the hole in the Shoe. This will reinforce the edges of the hole.
Use a nail the same thickness as the other holes of the belt.
