My backhoe never really had great heat but I was always so busy and like the cold anyway so never looked into it. After finally messing with the menu options last week on my JD 310 I found out there a spot that shows the actual coolant temp. It only it's 140-150 when working. Changed the thermostat yesterday and didn't change a thing. I don't believe the fan on those things have a clutch it runs locked with the speed of the belt continuously I seen other backhoes like that so does anyone know what else would cause this? I know some engines run cool but i can't see it supposed to be running this cool. I thought about blocking half the radiator like on a semi in the winter but I thought maybe then the hydraulic cooler wouldn't get enough air to it? Any thoughts? I'd like to fix it I feel like it's accelerating wear? Luckily i havnt used it much but not I have a ton of work for it
