[QUOTE="SkidTracks, post: 129714, member: 5570"] Working on a similar over heating problem on a T870 which has moved around. Originally, Engine over heating (previously only seen when debris was blocking air-flow) Moved to, Hydraulics over heating (never seen before, until several months back) Moved to, Diesel fuel over heating (never seen before) Done thus far: New hydraulic fan motor filter New hydraulic fan control valve (replaced twice - field / shop) New hydraulic fan system - motor included New hydraulic oil-radiator (cooler) New hydraulic return manifold block New hydraulic oil return filter by reservoir tank New hydraulic oil (Bobcat Red after flushing New hydraulic oil return temperature sensor (replaced twice field / shop) Bobcat dealer has no ideas at this point. Next up is Lower plastic fan shroud duct and Thermostat Thoughts? [/QUOTE]
