My temperature gauge I bought from OEM several years ago just stopped working. I bought a new one from them last week and installed it today. Ran the tractor and it came up to temperature just right. I later drove the tractor and it didn't work. I checked the water temperature in the radiator and it was at 180F. Made sure there was no air pocket around the probe by loosening the fitting, but still only a low reading. The old one I put in boiling water and it came up to the "R" on run, so it is not reading correct. Anyone else have trouble with the OEM temperature gauges? They claim to be made in the US. I am calling them tomorrow about it. Roger
