Hi. I am new, and trying to decide if I should give up pulling my horse trailer with my 99 Cherokee Sport for a few years. When it overheats, I usually pull over and run the heater until the engine cools down. I went to Vegas with two horses and had to go 30mph up the grade. I got some wetter water and ran the heater on each grade all the way home. Then I had the thermostat replaced along with a new radiator cap. Hip Hip hooray I towed for the first time without overheating. Then two weeks ago, she was getting hot, but the heater would not work. Being a blonde 50 yr old woman, I didn't know that meant I was out of coolant. So, a quick call to a repair shop who told me I had to stop and cool and put water in the radiator. I pulled over and put some water in my overflow, took the trailer off, and then had to start up to move it off....... Low and behold, the heat started coming through and temp went back down.

But the question is, where did the coolant go? I have seen her drip before, but not this time. I haven't towed since, but the temp is now running nice and under 210 a lot of the time.

I spoke to a radiator guy who thinks he could put in an aluminum radiator to help keep the engine cool. Should I pursue this or go buy a Chevy? Oh, I have 107,000 miles.
