Coolant Cap Water Leak

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Antifreeze coolant

If you have a water leak from the coolant cap, there are several factors to consider and many things to check. The first thing I recommend checking is the rubber hoses connecting the radiators. Why check them? Because being rubber, if they harden, they can cause water leaks. Another reason could be damage to the radiator due to age or a potential impact. A more serious reason for experiencing water leaks could be a break in the water conduits or deterioration of the gasket.
