So fixed the seat bar sensor. Now the coolant temperature light comes on and the hot Hydraulic oil light comes on and shuts down the machine. Weird thing is that sometimes it does it when the machine has only been running for a few minutes and sometimes not until running for an hour or so. Added some coolant and cleaned off the radiator. Getting error codes 07-11 (Hydraulic oil temperature extremely high) and 0821 (engine coolant too hot). Funny thing is the engine temperature gauge shows normal. Temperature doesn't seem extremely hot for a diesel but I am used to working on 6000 hp plus diesel electric locomotives.
