It seems as though my fan clutch is not working. I put in the fss for the sc2. Fan speed runs from 325 to 650. My temps are running 188-192 just regular driving. When pulling heavy loads, temps may run up to 202. I know it's cooler but I think the fan should be coming on more especially when pulling heavy loads. My heavy loads are round 26-28000 lbs. I have not seen the ect above 202. EOT temps are rite where they need to be.
Any of you pros know of any trick I can do to test short of taking it to dealer. Out of warranty on time but short on miles.
Did a good test today I think. Had a job where I had to drive about 1.5 hours to get to with my skid steer & hydro ax.It was a little warmer today so that was good. While pulling 28000 lbs I'm noticing the fan speed & ECT. When ECT gets to 206 the fan will begin to speed up. By 209-210, the fan speed will increase to 18-2100 rpm. It does cool down, but I never here the fan. I have always been able to hear it. I'm just wondering if the fan is slipping being it never goes over 2100. The engine was at 2900 rpm with the fan at 1900-2100. I am using a ScanGauge 2 for all my monitoring.
