The invention relates to a dosing module (10) for metering a reducing agent into an exhaust system of an internal combustion engine. Said dosing module (10) comprises at least one cooling member (22, 24) through which a cooling fluid flows that is used to cool the internal combustion engine. An electric contact (20) is located in the top region of the dosing module (10). The dosing module (10) is enclosed in a full housing (38) that comprises an upper and a lower cooling member (22, 24, 24) through which a directed cooling fluid stream (34) flows that runs from the valve tip region (18) in the direction of the electric contact (20).
