Topping up the coolant (VW Golf 4)

First, turn off the engine and let it cool down. Then cover the expansion tank cap with a rag and carefully unscrew it counterclockwise.

If under the circumstances you do not have the low-temperature concentrate G12 A8D, do not add any other concentrate to the system. In this case, only water can be added, at the first convenient opportunity it is necessary to restore the required composition of the cooling liquid by adding the recommended low-temperature concentrate.

If there is a large loss of coolant, it should be topped up only when the engine has cooled down to avoid engine damage.

Do not fill the coolant above the max mark: excess liquid will expand and flow out of the cooling system through the safety valve located in the plug.

Tighten the expansion tank cap securely.
