is it a big load? towing with a 15 year old car is a sketchy proposition- the thing was not even designed to tow- you will need a new cooling system, one that is high capacity- or a new truck designed to pull that weight-
Have you tried the orange coolant with hoat? Im running zerex g05 orange. I changed everything before realize that green coolant wasn't good enough for what i was trying to do hope this helps you
