Attention. When working, handle pipe connections with care. Use only recommended tools to prevent damage.
When a car engine is hot, the fluid in the cooling system is under high pressure. It is necessary to wait a few minutes before starting work on the components of the cooling system, making sure that the pressure is released.
Before starting work on electrical systems (connectors, electrical components, electrical wiring, etc.).
Note. When the battery is disconnected, the steering column lock assembly remains in the same state (blocked or released). If it is necessary to turn the steering wheel with the battery disconnected during work, the TEG must be left inserted when disconnecting the battery - in this case, the steering column remains unlocked.
It is forbidden to loosen the connections of parts before draining the refrigerant from the system.
To prevent the ingress of moisture, immediately close the open openings of the parts with caps or plugs.
Remove the protective plugs only immediately before installing the part.
When connecting fittings of parts, be sure to install new sealing rings, having previously applied refrigerant or oil to the fitting and seal.
If it is necessary to depressurize the cooling system, prepare in advance all the tools and spare parts that will be required to perform system maintenance so that the system is in a depressurized state for the strictly necessary time.
Close all pipelines and connections with plugs or plugs immediately after they have been disconnected to prevent dirt and moisture from entering.
All pipelines and other elements of vehicle systems stored in the spare parts warehouse must be hermetically packed until they are ready for use, or their openings must be closed with plugs.
Do not bend molded piping elements of the system to fit in place. When servicing refrigeration units, use piping elements of the required shape.
All fixtures, including the refrigerant charge manifold, pressure gauge manifold, and inspection hoses, must be clean and dry.
