How many years does a car hose usually last?
There is no hard and fast standard for this problem, which mainly depends on your vehicle maintenance. Cars that don't pay attention to maintenance,100000 kilometers must be replaced, because the water in the water tank has not been replaced, and there is no double oxidation outside the water pipe. If the water temperature is high, it will definitely crack. If you don't know the car very well, it will be more serious, such as cylinder flushing and overhaul. It is very serious. The concept of vehicle maintenance rather than repair is emphasized. It is not only easy to drive, but also has a high safety factor, because the maintenance power is sufficient.
Is it necessary to change the water pipes of the whole car?
It depends. The maintenance cost of repairing cars will increase year by year, especially in Europe and America, where the rubber parts and water pipes of automobile systems and engines are gradually aging and maintenance is not cheap.
First, observe whether the automobile water pipe expands. Some water pipes will be bigger than before if they are used for a long time. The most obvious thing is that the clamp of the water pipe joint is much smaller than the expanded water pipe, in which case the whole vehicle can be replaced.
Second, the engine water pipe is easy to harden. When the car is cold, you can squeeze the water pipe by hand. If you feel hard, you can consider completely replacing it.
Third, there have been many problems of water pipe joints leaking. With the increase of automobile mileage, the coolant will gradually acidify, corrode the pipeline, produce a lot of scale, and accumulate at the water pipe joint all the year round, which is easy to cause multiple leaks. In hot weather, when the internal pressure is too high, the water pipe may burst. If you can see red powder at the water pipe joint of the car, it is left after the antifreeze leaks and dries, which will lead to the gradual reduction of antifreeze.
Why does the car water pipe burst?
1, excessive pressure, poor waterway. Causing the water not to circulate. Especially at high speed, the water pressure is particularly high! Water pipes burst easily.
2, the water temperature is too high, resulting in high internal pressure of the cooling system and boiling of the water tank. Causes of high water temperature: lack of water, damaged impeller of water pump, poor working of cooling fan, such as damaged fan or temperature control switch, dirty waterway, poor working of thermostat, damaged cylinder gasket, excessive carbon deposition in combustion chamber, wrong ignition timing, etc.
When the engine is hot, it must be stopped for maintenance, so as not to leak water. You can turn on hot air in the car. Crappy mode to fix! It is possible to flush the cylinder pad after high temperature.
3. Dirty blockage of three-way catalytic converter will lead to poor exhaust and high water temperature.
4. The water tank cover is damaged, or the return pipe is dirty and blocked. Can't effectively relieve stress in time.
