Abstract
A filter device for an engine coolant includes a housing with an inlet for inflow of coolant and an outlet air outflow; a flow path extends between the inlet and outlet, a filter in the flow path filters the coolant; a dosage of corrosion inhibitor is disposed in the housing, corrosion inhibitor being separated from the flow path by a separating means exposed to coolant in the flow path; the separating means disintegrates by corrosion when coolant in the flow path has a corrosiveness above a predetermined level thereby releasing the dosage of corrosion inhibitor into the coolant.
