Can the cover of the Big Dipper water tank be changed from 1. 1 to 0.9?

465 engine intake bronchus has penetrated into antifreeze, and two have been replaced. Do you feel the pressure in the water tank is high? Can the raw water tank cover of 1. 1 be changed to 0.9? 465 engine intake bronchus has penetrated into antifreeze, and two have been replaced. Do you feel the pressure in the water tank is high? Can the raw water tank cover of 1. 1 be changed to 0.9? Cars are like people. New cars are like young people. It doesn't matter if your blood pressure is higher. Old cars are like old people. When blood pressure is high, they may get into trouble. Even the water tank cover of the original car is 0.9, and 1. 1 is generally modified. Those that enhance the performance of the engine can be used, which can greatly increase the boiling point of the coolant by increasing the pressure of the cooling system and prevent the car from boiling in sports mode. However, under such high pressure, the cooling system must be strengthened. For example, I used the thickened water tank and the water tank cover of explosion-proof water pipe 1. 1. When you warm the car, you pinch the water pipe, and the pressure rises so much that the water pipe can't be pinched. Switch back to 0.9 and pinch it again, it will feel softer. After the rubber of the water tank cover is removed, the sewer pipe of the hot car can also be pinched, indicating that the pressure has dropped. At this time, as long as there is no shortage of water, the fan works normally, and as long as it does not go to the plateau, there is no need to worry about a trip every two days, four or five kilometers at a time. Stop and check the auxiliary water tank, the antifreeze is two centimeters high, and the cold car returns to its original position. The thermometer is the same as before, half of it is a little low, and then it runs further. You still don't understand the structural principle of the water tank cover. The outer sealing ring ensures that the water tank is a closed system and will not enter the air. The small cover inside controls the pressure in the system under the pressure of the spring. When it is big enough, push open the small cover and drain a little water into the auxiliary water tank to relieve the pressure. When the water temperature drops and the pressure drops, the small cover will be sucked down, the water pushed into the auxiliary water tank will be pumped back, and so on. Removing the rubber ring of the lower cover means that there is no pressure in the system. After the water temperature rises, it can be drained to the auxiliary water tank at any time, and it can be completely sucked back after stopping and cooling. As long as the cylinder gasket is not boiled, no matter how far and fast you run, the liquid level of the auxiliary tank will only rise a little, and it is impossible to keep pushing water until the auxiliary tank overflows the tank cover. This design is of course reasonable, just to ensure that the circulating cooling system maintains a reasonable pressure, just like a pressure cooker. High pressure can increase the boiling point, such as 100 boiling under normal pressure, and the boiling of closed high pressure system may not start until 1 10 to 120, which is the original intention of designing this kind of water tank cover. The strength of water tanks and water pipes in many classic cars is not enough. Under the high pressure of the original system, antifreeze is likely to leak, especially like some hose joints and warm water tanks. If slow seepage is found, the pressure is pushed out. If you don't want to make a big fight to replace it, try to deal with the water tank cover to reduce the pressure, so it probably won't leak and there won't be any adverse effects, because I've been doing this for two years. There were some leaks in the upper and lower pipes of my house before. I want to change the water pipe so that the water in the auxiliary tank will not leak back if it runs too much. One is that the rubber ring outside the water tank cover leaks, and the other is that the water pipe inside the auxiliary water tank cover falls off or leaks, and the cylinder gasket leaks too much. The outer sealing ring is not allowed to run on the ground, is it? The internal sealing ring is used to release the pressure after exceeding the specified pressure. When there is no pressure, water can flow to the auxiliary water tank. Is the auxiliary water tank big enough? I wonder if there will be no water in the main water tank after half an hour of opening. If this can still be used normally, I can only say that the designer of the water tank cover is stupid enough, the sealing ring outside is still there, and the water can be sucked back into the water tank, reducing the pressure of the whole circulation system. The disadvantage is that the boiling point is easy to boil, and the advantage is that the pressure is low and it is not easy to leak, especially for old cars, water pipes and water tanks. I have taken off the sealing ring on the inner lid for several years. 15 After the water tank cover was made, nothing happened until 18, and it was 1.4. And if you don't listen to the bird's talk, the principle of thermal expansion and contraction will be fine as long as the rubber tube inserted in the water on the auxiliary water tank cover does not fall off and the rubber tube connecting the water tank cover and the auxiliary water tank does not leak. . Haha, no. Pay more attention to the temperature of the water tank and the amount of antifreeze. It should be no problem. There is no way. Two intake pipes have been replaced, and the third one has begun to leak antifreeze. Now it's good to say that it costs 500 yuan to go to 600 yuan for replacement during the warranty period. I don't know how to change the water tank cover of 0.9 now. I didn't do what you did, but wrapped a copper wire around the post in a small bowl. There is a gap. After ignition, antifreeze will run into the small kettle, just for fear that the water tank will run out of pressure. What's the harm of a long time @20 19.
