Coolant Cap Pressure
I have lost the coolant cap for my 2007 Holiday Rambler Neptune. The Cummins ISB 325 is actually a 2006 engine. My Cummins owners manual specifies a 7 PSI cap WITHOUT EGR, 15 PSI WITH EGR. Seems easy enough, but I am embarrassed to admit I don't know if my 2006 Cummins 325 (5.9L) is equipped with EGR.
So, my question: Does the 2006 Cummins ISB 325 in my 2007 HR Neptune have EGR?
I would just go look at it but it is temporarily stored some distance away and i would like to obtain the new cap before I travel to where it is. If your knowledge can save me an extra trip I will be grateful.
