[Auto maintenance knowledge]Emergency treatment methods for car leakage

Vehicles often fail due to oil, air, and water leakage during use, which not only affects the use, but also increases fuel consumption. Here is a simple emergency treatment method for leakage failure:

Reminder: The following methods and measures can only be used in an emergency, and the use time should be shortened as much as possible to avoid causing other problems.

1,tank,Water tankleakage

When the fuel tank and water tank leak, the common method is to temporarily stop the leak by applying soap or chewed bubble gum to the minor leak. If the radiator core of the water tank is damaged, the damaged radiating copper pipe can be gently clamped flat with needle-nose pliers until it does not leak water. If there is adhesive patching, you can use the patching method to solve the leakage: drain the oil (water) in the tank, remove the oil and rust on the surface of the leak, and use the "two in one" glue on the leak after cleaning. The surface is evenly coated, and it is applied again after half an hour. The glue patch can be tested after 2 hours, and the maximum strength can be reached in 20 hours. This method is simple to operate, safe and reliable, and is a good emergency solution for oil tank and water tank leakage.

2. Leakage of pipe joints

Pipeline joints are prone to leaks due to cracks and threaded sliding fasteners, resulting in oil leakage (gas, water), and the vehicle cannot operate normally. In this case, if you feel that it is leaking at the joints, but you can’t find the specific location of the leak, you can use butter, soap,SealantCoat the entire joint; such as the internal thread sliding buckle of the joint, can be wound on the joint with raw material tape, twine, glove thread, asbestos rope, etc. The gasket made of lead wire, because these materials are soft, is good for sealing.

3. Pipeline leakage

Piping leaks are generally easier to identify specific locations. If the low-pressure pipeline leaks, wrap tape or plastic sheet around the leak and tie it tightly with iron wire on the outside; if there is no tape, cut off the leak and use hose, plastic pipe, iron pipe, bamboo pipe, etc. to tie it tightly. ; If the problem still cannot be solved, short-circuit methods can be used to temporarily remove the pipelines of individual parts that will not have a significant impact in a short time.For example, if the diesel engine dieselFilterIf the oil pipe to the oil transfer pump leaks, the oil pipe can be removed, and the oil tank outlet pipe is directly connected to the oil transfer pump (the diesel filter is short-circuited at this time); dual pipelinesBraking SystemIf one of the systems is damaged, the damaged vehicle can be removed; if a cylinder leaks in the pneumatic braking system, the intake pipe of the leaking cylinder can be blocked. The replacement method can also be used to solve the leakage problem. For example, if the key pipeline on the vehicle that affects normal use is damaged, consider removing other pipelines and temporarily replacing them with key parts.

4. Leakage caused by damaged gasket

If the gasket is damaged and leaks, you can apply sealant, butter or paint on the joint surface to strengthen the seal; you can also use cardboard with the same thickness as the original gasket to make the gasket, and some parts can also be made of cloth for temporary use.

5. Leakage caused by the loss of elasticity of the cylinder head gasket

The leakage caused by the loss of elasticity of the engine cylinder head gasket is difficult to achieve by tightening the cylinder head bolts. When there is no new product to replace, you can put the old cylinder gasket in a pot filled with waste engine oil, heat the oil to about 100℃, and take it out after about 20 minutes. The asbestos in the cylinder gasket will expand and the elasticity can be obtained to a certain extent. Recovery. However, this kind of cylinder head gasket cannot be used for a long time, and it should be replaced in time if there is a new cylinder head gasket.

6. Self-made O-ring for plugging

When repairing the vehicle, if there is no special type of O-ring, the following methods can be used to make an emergency. ①Choose a slightly longer O-ring with the same diameter as the required O-ring, cut the required length, and then bond it with 502 glue at the disconnection. The result is very good after use. ②If there is no other suitable material, it can be usedtireInner tubeCut into O-rings with a rectangular cross section, which is especially suitable for sealing high-pressure oil pipe joints.

7. Water seal,Oil sealLeakage caused by damage

　　Water pumpIf the water seal is damaged, auxiliary sealing materials such as glove thread or asbestos rope can be wound on the outside of the water seal, which can usually be solved. When the oil seal is damaged and leaks, the direction and position of the oil seal can be changed, and sometimes it can take effect. If the spring ring in the frame is damaged, it can be replaced by a small ring made of thin steel wire; a small retaining ring can also be installed on one side of the oil seal to improve the sealing performance and pressure resistance of the oil seal.
