demo man- Thanks. Someone the other evening mentioned a washer being used on a tractor, just a bit of restriction, like you say too.
On January 12th, in the evening, I started a thread called, Why does my truck hate thermostats? This last one was a 160 degree Prestone High Performance...
I'm going to see about removing the innards from the 180 degree one that I have & give it a try.
