Q: Temperature Gauge not working after Coolant system work

asked by on July 28, 2017

I experienced an overheat while hauling a heavy load (13K) up a 6-7% grade. I wasn't sure whether it was the water pump or cooling fan. During this time, the heat stopped working on the truck. I replaced the tstat, water pump, fan, and temp sensor. Now I am not getting a reading on my dash temp sensor gauge. I check the sensor with multimeter and all is well. What am I missing here?
