Water is leaking from under my car Will the thermostat make water run a 325I BMW 2005?
A thermostat regulates the flow of coolant in a car's engine, not water. A water leak under your car is likely due to a different issue, such as a faulty hose, broken water pump, or damaged radiator. It's important to identify and fix the source of the leak as soon as possible to prevent further damage to your vehicle.
