2017 deere 333G. Sn:1TO333GMKHF319372 Coolant temp been getting warmer than usual. It's usually 180 degrees F. N been getting 210 just tracking down the road. Cleaned radiator out n it's clean, pulled the hydraulic temp sensor plug fan went into full speed so ruled out radiator n fan speed. Also did a full service change all fluids and filters I looked into the parts book for themosat location n its in the water pump. Have you guys changed the water pump or themosat on them things? Can it be accessed by removing air filters housing and bracket? Any advice?
You sure the radiator is clean? put a light on one side and look through the other side to see how much is still there. The temperature of the thermostat housing going to the radiator, and the water pump inlet coming back from the radiator, when it's 210, will help guess better what's going on. The idea is to get the top and bottom temps of the radiator, but you can't always "see" those places, and don't shoot shiny metal because it won't reflect so won't read correct temperature.
On large frame Deere SSL's, fan speed has to be ruled out second, after checking package cleanliness and seals. Just because it sounds fast doesn't mean it is reaching full speed. It needs to be measured with a photo tach with all fluids at operating temperature and the engine wide open. The specification is 2450-2600 rpm. Post your results. Your machine also has new software versions available for all your controllers. I suggest you get that done. I know the EMU and the HCU software does address some of the fan speed parameter settings (fan reaches full speed at a lower temperature). According to what I see, your machine has the older software.
