Driving car radiator on the way. What to do?
What to do if the drift of the car cooling radiator? There are several solutions to the problem that will help stop leaking with your own hands and give time to get to the car service.
The flow of the cooling system on the road unequivocally testifies to the wear / crack of some details and various sealants to eliminate leaks - this is only a short-term solution to the problem, which will gradually lead to repairs with the replacement of parts. therefore do not consider the means to eliminate the flow of the cooling system as a medicine from trouble, any case is only a temporary solution.
If in the long road, the radiator is low, and there is no possibility to spare or flush the crack, remove the safety valve from the radiator tube. Excessive pressure will disappear, and flow will decrease or completely stop.
Special sealants - Fast elimination of low leaks
Often the radiator or the cooling system nozzles begin to flow into the far road. For such cases of rapid repair on the road there are special sealants that eliminate small leaks in the cooling system - It is enough to pour the jar to the radiator or a coolant tank.The composition for repairing radiators
Reliably eliminates the leaks of antifreeze from the radiator and other elements of the cooling system. It does not evaporate, withstands the high temperature, remains in the system and prevents the emergence of the leaks in the future. Safe for steel, cast iron, color alloys, plastic, rubber. Compatible with all types of cooling fluids. It does not score a radiator tube, hardens only in places of leaks.Such seals are able to overcome to flow in the radiator, at the junction of nozzles, but most manufacturers indicate that the size of the leak hole should not exceed 1.5-2 kV. mm - i.e. These are small cracks, holes. Staying in coolant, sealants and themselves are in a liquid state, and after leaving, they are "frozen" under the influence of air, and form a hermetic polymer film around the leak place.
These funds exist nuances, and not so pleasant - such sealants can over time can be cloging the cooling system, so after applying the sealant, the complete flushing of the cooling system is highly recommended. Yes similar solution to the problem of leaks short-term. But in order to get home or ride a few days in search of parts for repair - the solution is suitable.
"Cold welding" and "metal-sealants"
For more serious repair of radiators (with large cracks), it is possible to use materials such as "cold welding" - it is heat-resistant adhesives, which introduced a metal powder. Cold Welding can be produced both in the finished form and in the form of individual components that should be mixed with each other to obtain a homogeneous mass.
Plastic cold welding
Quick-drying adhesives-putty with steel, bronze and titanium fillers. "Grab" in 5 minutes, harden in 15, may be machined after an hour. Have excellent adhesion to all materials. Glue glass, metal, plastic. A distinctive feature is a volume extension at the time of "setting", i.e. The effect of "traffic jams" occurs. Therefore, it is possible to repair when leakage fluid from a damaged unit. Leaf stops after 5 minutes and forever.It is "plasticine", which is applied around the damaged part, first cleaning and degreased it. Cold welding is captured in a couple of minutes, but it takes a complete hardening to 1 hour. Due to the fact that cold welding holds very well and has a temperature expansion coefficient similar to the metal, such a patch on the rolling radiator is sometimes able to serve several years.
Cold welding may be more useful than the whole drawer of auto tools and gaskets. And most importantly, it attaches confidence in the most unpredictable situations, for example, when driving radiator or gas tank in a long road.
For search for invisible refractory leaks There are special devices. The leak search kit consists of a fluorescent additive, a pistol for entering this additive to the cooling system and UV lamp, the light of which highlights the penetrating the coolant with a fluorescent additive. However, such sets are intended for the service, for private use, they may be expensive.
Determine the place of leakage The color of antifreeze will help if there are fluorescent supplements in it. The main thing is to inspect the cooling system nozzles, especially in the connection places. It can loosen the fastening clamp or the crack form.
