The role of the engine outlet pipe.
The main function of the engine outlet pipe is to discharge the coolant to ensure the normal operation of the engine and heat dissipation.
The engine outlet pipe, also known as the downpipe, is an important part of the cooling system. Its main function is to export the high-temperature coolant after the internal cooling of the engine, dissipate heat through the water tank, and then return the cooled coolant to the engine for recycling. This process is essential to maintain the normal operating temperature of the engine. If there is a problem with the outlet pipe, such as blockage or damage, it will lead to poor coolant circulation, which will affect the heat dissipation effect of the engine, and even cause the engine to overheat and damage the engine parts.
In addition, the design and material of the outlet pipe is also a key consideration to ensure that it can withstand high temperatures and pressures, while maintaining good sealing performance to avoid coolant leakage. Regular inspection and maintenance of the state of the outlet pipe, such as checking whether there are cracks, aging or blockage problems, is of great significance to ensure the safe operation of the engine and extend the life of the engine.
In short, the engine outlet pipe effectively protects the engine from overheating damage by ensuring the circulation and heat dissipation of the coolant, and is an indispensable part of the automobile engine cooling system .
Where is the engine outlet pipe?
Front windshield wiper sides
The engine outlet pipe is basically located on both sides of the front windscreen brush, usually one on the left and one on the right.
The engine room is a relatively open environment, sewage, foreign bodies, etc. will flow into the engine room along the windshield. The engineer designed a water baffle at the rear of the engine room and at the lower edge of the windshield glass, and designed a drainage hole at the position of the baffle. These drainage holes are connected to the front of the sunroof, where water from the sunroof flows along the A-pillar conduits, where it meets with the engine room water in the fender and is discharged near the wheel fender. Sometimes the leaves and muck from the washing will seep into the drainage hole, causing the drainage hole to be blocked, and the water will penetrate the sealing strip into the engine compartment. Therefore, it is very important to check and clean these drainage holes regularly to prevent the potential hazards caused by the long-term wetting of the wiring harness in the engine compartment and the possible backfilling phenomenon of water.
What is the cause of the high pressure of the engine outlet pipe?
The high pressure of the engine outlet pipe may be caused by a variety of reasons, mainly including cooling system problems, reduced pump performance, radiator problems, etc.
First, cooling system problems are a common cause. If the coolant is insufficient, it will lead to the gradual loss of the coolant in the cooling system when the engine is working for a long time, and if the owner does not find and add the coolant in time, it will cause the engine to overheat, which will affect the pressure of the outlet pipe. In addition, if the radiator tube leaks water or is partially blocked, it will also affect the circulation of cooling water, resulting in overheating of the engine, thereby increasing the pressure of the outlet pipe.
Secondly, the deterioration of pump performance is also an important factor. If the pump seal is damaged, resulting in a drop in the pump water, unable to carry out an effective cooling cycle, it will make the hot water in the engine can not be effectively sent to the radiator for cooling, resulting in overheating of the engine, increasing the pressure of the outlet pipe.
Finally, the radiator problem can not be ignored. If the two valves on the radiator cover that pass steam outward and air inward do not work well, it is impossible to control the boiling point of the cooling water in the cooling system, so that the engine can not work at normal temperature, and then affect the pressure of the outlet pipe.
In summary, the pressure of the engine outlet pipe may be caused by a variety of factors such as insufficient coolant, lack of water or partial blockage of the radiator tube, reduced pump performance and radiator problems. Fixing these problems usually involves checking and servicing the cooling system, replacing damaged parts, making sure the pump is working properly, and servicing the radiator .
