Hi, my truck overheated and i replaced the radiator because it had a leak. I then realized the thermostat was not working so i replaced that. Now i have it on the computer and it states that it is not overheating however the needle on the gauge inside the truck is not moving, do you have any suggestions? Thank you very kindly. Rosie

engine coolant temperature sensor/sending unit for gauge is probably faulty
