I have a case 9020B the engine oil temp is running one bar below the red line what should I look for?, the radiator and screen are clean
Does it have a oil cooler?? Perhaps damaged or colapsed hose?? Check operating temp of oil pan with a infared temp tester. Check cooling system also.
PHP: I am attaching the probable causes of high engine oil temperature.
How is the coolant temp?
I don't recall a 9020B ever having an engine oil temperature gauge. They did have coolant temperature gauge and they usually went bad after a few thousand hours. The solution was to check temps with an infrared thermometer and then install an aftermarket gauge in the cab.
Could it be a hydraulic oil temperature guage?
