Up until a short time ago, everything was running fine. Now, in a short period of time, the hydraulic temperature light comes on and the oil is hot. So far, he has changed oil and filter, put a new temp sending unit in, and cleaned the radiator and oil cooler. We have looked online and haven't been able to read anywhere else about what might be causing the overheating. Does anyone have any ideas? Thanks in advance.</p></blockquote><p></p>
