Silverleaf vs. Coach Gauges
Re: Coolant Temperature. Coach gauges (2007 Country Coach w/Cummins 400 ISL) run cooler than Silverleaf by about 9-10 degrees. Question: Is it the coach gauges or the Silverleaf that signal the Engine Warning light to come on? When Silverleaf coolant temp reaches 225, Engine Warning light comes on while coach gauge is around 215-216 (always runs 9-10 degrees cooler than Silverleaf). As soon as heavy climb is over, temp immediately returns to 185-190. Have blown a head gasket and an intercooler, had the fan motor and controller replaced. Not even sure if these temps are all that high, particularly considering we hit these temps when outside air temp was 105 degrees and only on steep grade. Second question: Can Silverleaf coolant temp be calibrated to match coach gauge? Any help would be appreciated. (Silverleaf model is VMS 240 CL)
