I changed the radiator fluid a year ago in my 2000 toyota tundra with the 4.7L V8, i put amsoil radiator fluid in it and I notice it had the factory radiator fluid in it that was the color of purple about and the amsoil fluid look like normal radiator fluid that is green, but know when i go mudding it will over heat fast and today when it was just idleing it started getting hot, and i also notice that at normal temps it seem to sit higher then it did when i had the factory radiator fluid in it. So should i change the fluid to factory fluid and change the radiator thermostat?
