Hey guys, have a 2004 New Holland LS170. The other day the red coolant light came on and it started beeping and the temp was at 212. I turned it off and replaced the thermostat and engine temp sensor. Now when I run it or turn it on, the yellow coolant light stays on and the engine temp stays displayed on the screen and no longer shows the engine hours as it used to. The temp is staying around 175-180 now and not overheating, just can't get the yellow coolant light to turn off and also not show engine temp on screen. Any help is much appreciated!
