I've got a Cat 239D with just over 900 hrs on it , recently it's been running warmer than normal in the 203 - 208 degree range. It has the variable speed hydraulic fan that doesn't seem to be spinning fast enough to move enough air through the radiator. I've pressure washed the radiator multiple times to be sure it's clear now if I unplug the solenoid on the fan motor it will spool up and cool just fine any suggestions on how to test the solenoid or just replace it ? Also have been told that the hydraulic fan motor may need to be calibrated, any feedback on that ?
Thanks,
