Warnings: When opening the expansion tank cap on a hot engine, care must be taken, as escaping vapors can cause severe burns. To do this, close the cap of the expansion tank with a thick layer of cloth and slowly unscrew the cap until a hissing sound is heard. After the hiss stops, slowly unscrew and remove the cap from the expansion tank.
Do not allow coolant to come into contact with clothing or body paintwork. Otherwise, rinse the surface with plenty of water.
All clamps and clamps that are damaged or cut during disassembly of the cooling system must be replaced with new ones during assembly. To fasten band-type clamps, it is necessary to use special VAG 1921 pliers. All removable gaskets and sealing rings must be replaced with new ones. When assembling, the arrows on the elements of the cooling system, if any, must be aligned.
Drained coolant must be collected and disposed of.
