2、Technologies, LLC Page 1 of 15 COOLANT CONCENTRATE, PHOSPHATED ORGANIC ACID (POAT) WSS-M97B55-A SILICATE, BORATE AND TRIETHANOLAMINE FREE NOT TO BE USED FOR NEW DESIGN 1. SCOPE When mixed 50/50 with water it shall be a satisfactory fluid for vehicle cooling systems that contain aluminum engine compo

3、nents, radiators and heater cores, ferrous metals and copper brass. These materials are for initial fill and service fill. 2. APPLICATION WSS-M97B55-A was originally released for passenger vehicle applications. Products listed on the Ford Approved source list meet this specification. Some materials

4、were intended to be used at a 30/70 mix ratio, therefore, will contain a higher inhibitor level when diluted to 50/50. Other materials are intended to be used at a 50/50 mix ratio and therefore, contain less inhibitors. Refer to the details on the approved source list for relative inhibitor levels.
