This pink stuff is the Jeep coolant for the 2005 Liberty that has been going through the latest flush cycle.
I was so happy with the outcome of the Cherokee, I did my wife's jeep in a 2 month cycle.
3 and a half gallons later it looks very clean. I will never have to flush a coolant system again. This slow way of replacing the coolant puts no shock on the engine or coolant system what so ever. I will never for get how one time i flushed a entire coolant system,and noticed the temp gauge went to 290 degrees!!!!!!!!!!!!!!!! I was very blessed I did not crack a head gasket or head.
