Will the bursting of the car's water tank cause the engine to break through the cylinder?

1. Yes, the water tank will notPull the cylinder immediately, but after the water tank is out of water for a period of time, the engine temperature rises, resulting in the cylinder being pulled.

2. Even if the water tank of the car is broken, you must not drive. The rupture of the car water tank may cause the loss of the cooling system, and it is easy to cause the cylinder to be pulled when the engine is severely high. The reason for car rupture: no antifreeze was added in winter. The cold water broke when it is frozen.

3. Due to the high temperature, the wear of the piston will be aggravated, resulting in uneven temperature changes, affecting the power of the car, and the cylinder pad of the car will also be hot; if the piston ring pulls the cylinder and other faults occur, serious will cause permanent damage to the engine.

4. The car cannot continue to drive after the water tank breaks while driving, because the water temperature is too high, which will cause the piston, steel wall, cylinder, crankshaft, etc. to be too high, the oil to become thinner, and the lubrication effect will be lost.If the engine is turned off immediately at this time, the parts will be in a state of expansion, and the gap between the accessories is very small, which will cause some soft metals to fall off and even stick to the cylinder.

Is the engine cylinder block breakdown man-made?

1. No. The cylinder block breakdown is generally broken by the crankshaft connecting rod system, or the valve rod falls into the cylinder.

2. Water enters the cylinder block. It is relatively rare for the connecting rod to break through the cylinder block. Generally, it is because there is water and the oil is not lubricated well, resulting in the cylinder block to break through.

3. Hello, dear! There will be a shortage of water when the cylinder is boiled through the cylinder. There is a missing cylinder phenomenon between the cylinder and the cylinder cylinder, and the exhaust is uneven. The car is unstable. The cylinder and the oil channel will burn the oil.

4. Eventually, it will cause the outer side of the pin hole to fall off, and if it is serious, it will crush the cylinder block. The piston configuration is wrong. It is found that this piston was originally equipped with an ordinary machine with a burst pressure of 10MPa, which is now directly used in the turbocharged engine with a burst pressure of 15MPa, which exceeds the allowable value, causing the inside of the pin hole to crack, and the high-temperature gas to break under the crack, resulting in the top of the plug.

The hood has been pierced. Should the hood be replaced or just repaired?

1. If the damage is serious, it is better to replace it directly, because after the hood is welded to sheet metal, it is easy to rust and perforate, and large-area sheet metal is even more so. And the hood is on the engine, which is subject to cold shrinkage and heat rise, and water vapor erosion, rusting will only become faster.

2, but if the damage is serious, it is better to replace it directly, because after the hood is welded to sheet metal, it is easy to rust and perforate, and the large-area sheet metal is even more so. And the hood is on the engine, which is subject to cold shrinkage and heat rise, and water vapor erosion, rusting will only become faster.

3, but if the damage is serious, it needs to be replaced directly with a new one.Because after the hood is welded by sheet metal, it is prone to rust and perforation, and the hood is above the engine, which is subject to cold shrinkage and heat rise, and water vapor erosion, rusting will only become faster.

4. If the hood of your car is deliberately scratched, you have the right to require the other party to bear the corresponding responsibility and compensation. However, it may not be reasonable to ask the other party to compensate for a brand-new hood, because the amount of compensation should be based on the actual cost of repair or replacement.

Will the power cord be broken by the Corolla 1.2 engine compartment

As the title says, if you need to connect the wiring to the cockpit in the engine compartment? Basically, thick rubber is stabbed with sharp scissors. Use wire to lead.Install a front radar? I directly decorated the store. It seems that there is a wire tube. Observe it slowly. I hope you can find it.

Due to the need for modification, the wiring from the engine compartment to the cockpit is now threaded under the triangular plastic cover next to the front door. Although the wiring is very convenient, the disadvantages are too obvious. When the door is opened, the wire will be seen. Is there a hidden threading method? It's better to provide a photo reference.

Are you asking how Corolla wires from the cockpit to the engine compartment? Its method is as follows: according to the data of Pacific Automobile Network, park the vehicle in a well-lit place and open the engine compartment.

After opening the engine compartment cover, you can see the inside of the cockpit from this hole, which is under the driving computer. Note: The rubber plug is from the cockpit to the cabin card.If you live, you can choose to poke the stopper with a screwdriver from the cabin, and the stopper will fall into the cockpit, or you can pry up the stopper in the cockpit with a word.

50 The engine is broken after the overhaul of the bell hook machine. Why does the big throttle wear oil?

1. In the high temperature season or under the condition of severe engine wear, the choice of high-viscosity oil is conducive to the formation of oil film and reduce engine wear.

2. Engine oil, that is, engine lubricating oil, can play the role of lubricating and reducing wear, auxiliary cooling, sealing and leakage prevention, rust and corrosion prevention, shock absorption and cushioning and so on. It is known as the "blood" of cars. Oil is composed of two parts: base oil and additives.

3. There may be a problem with the sealing of the engine piston, resulting in an excessive gap between the piston and the cylinder wall. Under the high temperature season or severe wear of the engine, the selection of high-viscosity oil is conducive to the formation of oil film and reducing engine wear.

The reason for the engine piston perforation

The piston perforation in the engine is likely to be caused by the oil nozzle urination.

Piston perforation: The connecting rod should be connected under the piston and connected to the crankshaft through the connecting rod. The piston pin should be installed in the piston hole, and the piston should be connected to the connecting rod through the piston pin. The piston is a part that makes reciprocating movement in the cylinder block of a car engine. The basic structure of the piston can be divided into top, head and skirt.

The oil nozzle is leaking.According to the query of Pacific Automobile Network, the engine has a piston perforation, which is due to the oil leakage of the oil nozzle, resulting in excessive temperature perforation at the top of the piston. Some long-term misoperations accumulate less and more, which will eventually cause the engine piston to be perforated.

Piston perforation: The connecting rod should be connected under the piston and connected to the crankshaft through the connecting rod. The piston pin should be installed in the piston hole, and the piston should be connected to the connecting rod through the piston pin. The piston is a part that makes reciprocating movement in the cylinder block of a car engine. The basic structure of the piston can be divided into top, head and skirt.

The reason is that the inside of the engine is overheating. The water temperature of the 460 liberation piston machine engine is too high or the oil lubrication is poor, which will cause the internal overheating of the engine, causing the piston to deform or uneven heat expansion and cold contraction, resulting in piston perforation.
