I have a cooler installed now, but am in the process of adding a Perma Cool filter with a Dakota digital temperature gauge. I want to be able to filter anything that might clog any of the lines within the system. I think that the filter is just additonal protection, and I want to know what the temperature of my fluid is at different driving conditions. I don't do much stop and go traffic, mostly highway driving. Thanks for all of the tips and thoughts.
