Keith Browning Posted June 2, 2008 Share Posted June 2, 2008 For our CAT Gurus, will a 2007 C-7 de-rate for a low coolant concern with the check engine and stop engine lights flashing? This had the following logged event codes 111-1 and 111-17. Other than the usual low coolant I found nothing wrong and corrected the concern with adding coolant to the MAX line... we have a SSM on this. Just curious.

Alex Bruene Posted June 2, 2008 Share Posted June 2, 2008 I have seen several with a check engine and stop engine due to low coolant... but I have never noticed if they will derate or not. Quote Link to comment Share on other sites More sharing options...
HeuiTim Posted June 9, 2008 Share Posted June 9, 2008 yes, derate than shutdown, needs fatory passwords to clear code. Quote Link to comment Share on other sites More sharing options...
