soo i got stuck in a deep hole not to long ago, got a lot of mud in my engine bay, killed my second knock sensor so now both are out...problem; my truck's been over heating ever since, its fine if i have the heater on full blast but if not itll get over 210...i thought it was because both knock sensors were out but was told no thats not it. i cleaned the radiator as best as i could, lot of mud, still gettin warm. i need help bc its no longer cold down here and id like to use my a/c lol. only codes it threw were the knocks. also check engine light recently went off for some reason...HELP!!
