Maybe so buddy but, HOAT is very good coolant my system is super clean. I even changed my 98 over to it after flushing it out really good with distilled water for about a month. I noticed the water pump stays cleaner and so does the block too using it. I don't care for Chrysler much but, I do feel they did there homework on this one as well as Ford as I have not heard of any body I know with a Ford having problems. I can't speak for Diesel's but, can for cars and there light trucks.
