TimberJack Posted 8 hours ago Share Posted 8 hours ago 2008 CHU with MP8 keeps popping up low coolant and derate with the tank full. I’ve replaced the tank, sensor and short harness. It only pops up when you come to a stop. Once you get to rolling it will sometimes go off but normally you have to cut the key off and wait a few minutes. Does any have wiring diagram? Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/76344-low-coolant-alarm/ Share on other sites More sharing options...
