Instructions for Topping Up Coolant

Model: Volvo S40 MK 1 - Years 1995-2004
Part: Antifreeze coolant

Before topping up the coolant, first check why the level has dropped: it could be a leak or consumption caused by a potential head gasket malfunction. Without neglecting this detail, the top-up should be done with the appropriate antifreeze, which not only prevents freezing at low temperatures but also ensures that rust or deposits do not form in the system. You can choose a ready-to-use formula or a concentrated one to dilute; if you must use water, use distilled water.
