Lmackattack Posted October 5, 2008 Share Posted October 5, 2008 Any of those 3 sencers will trigger the shutdown light. If you have good oil press, proper water level and water temps are normal and the light is still on, one of the sencors might be bad?Most times I find that after the hot summer with an older mack that has no overflow coolant tank, the water level is a little low and needs half a gallon. just my .02Trent Quote Link to comment https://www.bigmacktrucks.com/topic/4272-r600-shut-down-light/#findComment-22509 Share on other sites More sharing options...
