I am using the Canton
oil cooler thermostat. I like the fact that it opens at about 215. This is just when the
oil is hot enough to boil off the water that has accumulated from condensation. I also installed the Canton Accusump. I am happy with the way they work. I really don't think the
oil cooler has opened that often, but I am sure it has a few times in the city. There are pictures of the installation in my gallery.
