I picked this Case 580 super E with the 4-390 non turbo Cummins - it's been a great machine and with the help of this forum I've been able to repack almost all the cylinders as they've been slowly leaking.
My water temp gauge had never worked since I bought it last fall. While repacking the boom cyl I ordered a new gauge and installed it, after installing the temp rose steadily into the red where it remained. I shut machine down made sure I cleaned any junk from radiator with a nice deep cleaning and flushed all the fluid from the system which looked good. I started it up and it steadily climbed to the red again. Thinking it might have been a bad cheapo sensor from amazon I bought a more expensive replacement sensor from mybrokentractor and reinstalled.
The water temp gauge stays in the red level (pictured) but then settles down just over the green/red after operating for a whole. I ran it for about 45 mins doing some work and it barely fluctuated from there. After running it I checked the upper hose which was hot, the lower hose was barely warm and opening up the radiator cap (slowly...) with a digital temperature gauge found the coolant to be at 153 degrees
Do I have just another crappy sensor? It runs great but if I'm causing any harm to it I'd rather track it down, however I don't want to throw parts at it if everything is operating fine
