When mixed 50/50 with water it shall be a satisfactory fluid for vehicle cooling systems that contain

3、 aluminum engine components, radiators and heater cores, ferrous metals and copper brass. This material is for initial fill and service fill. 2. APPLICATION This specification was released originally for passenger car and light truck and commercial truck applications without the use of nitrites. It

4、should not be mixed with previously approved coolants including silicated coolants per WSS-M97B51-A1.
