i am getting ready to install a 6.0 tranny cooler and inter cooler on my 01 7.3 psd, i was going to install a coolant filter and wanted to run some elc coolant. i am considering the evans. i was wonder if anyone is running it or what other options there are for elc coolant for diesels. i prefer not to have to test it and put additives in it over time, as i was told i wouldn't have to do that if i run the evans coolant. thx for you input, rm
