Distinguishing between genuine and fake water pumps

Firstly, the packaging of original water pumps or supporting manufacturers' products is generally standardized, with clear and formal handwriting, detailed product names, specifications, registered trademarks, factory names, addresses, and telephone numbers; Counterfeit accessories usually have rough packaging and unclear factory address and name printing.
Secondly, qualified water pumps have a smooth surface and good workmanship. The more important the spare parts, the higher the processing accuracy, and the stricter the packaging rust and corrosion prevention. If rust spots, rubber cracking, loss of elasticity, or obvious machining patterns are found on the surface of the shaft neck when purchasing, it should not be an original accessory from the factory.
Thirdly, the appearance of low-quality water pumps can sometimes be good. However, due to poor manufacturing processes, it is easy to be damaged. When purchasing, simply observing the hidden parts such as edges and corners of the accessories can reveal the quality of the accessory's craftsmanship.
Fourthly, some water pumps are refurbished from old parts, and in this case, the old paint can be found by simply removing the surface paint of the parts. It is best not to use such water pumps.
Fifth, when installing the purchased spare parts into the car, it depends on whether they can be compatible and have good compatibility with the parts. Generally, original factory parts can be well allocated to the car, while inferior parts are difficult to match well due to poor craftsmanship and large processing errors.
Sixth, in order to ensure that the assembly relationship of the water pump meets the technical requirements, some regular parts are wrapped with assembly marks to ensure the correct installation of the accessories. If there are no marks or the marks are blurry and cannot be recognized, they are not qualified accessories.
Seventh, a regular water pump assembly and components must be in good condition to ensure smooth installation and normal operation. Some small parts on the assembly are missing, which makes it easy to install and cause difficulties. These parts may be counterfeit.
Eighth, some important accessories, especially assemblies, are usually accompanied by instructions and certificates of conformity when leaving the factory to guide users in installation, use, and maintenance. Counterfeit assemblies generally do not have detailed installation instructions to guide these.
