Antifreeze — General Information and Replacement (VW Golf 2)

1. The manufacturer fills the cooling system with g10 or g11 fluid. Every 15,000 km or 12 months, it is necessary to check the concentration of the coolant and, if necessary, top up with new fluid.

2. The liquid must be in the system at all times, as it prevents sediment formation and provides a higher boiling point than ordinary water - this provides better cooling efficiency, especially when the engine is running at full load.

3. It is recommended to check the concentration of antifreeze before each winter season. The concentration can be checked with a hydrometer. If you do not have a hydrometer, but have doubts about the normal thickness of the coolant, it is better to replace it than to risk getting a cracked block or head. The concentration should never be less than 40%.

4. Before adding coolant, it is necessary to check the tightness of all rubber hose connections.
