08/04/17 - This morning I left Hardin, Montana about 9 30 am.  I had about 277 miles to the Walmart in Butte, Montana.  I drove a while and then stopped for fuel and I had been munching on some chips along the way so decided to drive to the second rest stop.  It was rather warm outside and I was going up hill when all of a sudden the temperature gauge went up between normal and hot.  Much hotter than it had been running all this time.  I was scared because it would not come down and of course I was many miles from an exit but did find a little bit of an turn off so stopped there on the incline so see what was going on.  My little coolant tank in the back was overflowing and I could not figure that out since it was fine before I left.  I then had some coolant in the trunk of the car so decided that I needed to put some in the narrow black container that Aunt Ada and I had done before when I had the huge leak. It must have always been cooled down when we did it.  Well, there was an angel there because I decided to open that and later learned from my nephew Jeremy that it was the actually radiator and as soon as I released it a tiny bit, all kinds of things started to come out of it and the pressure was huge.  Anyway, I did not get burned but had stuff all over my shirt, pants and some evidently on my face because I could taste it!  I let it finish and then lots of steam came out so I waited awhile until no more steam and poured the coolant in, closed everything up, and started out again.  I drove much slower because I had been cruising at about 64 miles per hour.  I went down to 50 miles per hour.  I had about 15 miles to the rest stop and the temperature gauge held at the first mark.  I then had lunch, tried to settle the nerves and took off again.  I drove 55 miles per hour and the temperature was doing well.  I had 72 miles to the Walmart in Butte, Montana.  My scheduled stop for the night.  After leaving the rest stop, I stopped at a Flying J to buy more coolant in case I needed it because I had no idea how much I had lost when it exploded all over the place on the hill.
Things went OK until I started to climb again because I had the continental divide to go over but I was lucky because there was a semi truck who also was in trouble and we made that long climb together at 25 miles per hour.  The temperature did climb to normal but did not go beyond that on my climb.  I made it safely to Butte.  Tomorrow morning before I leave, I will add some more coolant just to make sure the level is good.  I checked the map but could not let if I had any more passes to go through but my first cousin Onita seems to think I might have one more.  I will just plan to drive very slow and also it is suppose to be cooler tomorrow as well.  Jeremy did let me that the outside heat of 93 degrees probably did not help it as well.  Off to bed.
