i have a 2001 chevy monte carlo ss 3.8. temperature gauge works but fans wont engage when they are suppose to. If I unplug the coolant sensor fans will come on. how can i fix this?
FAN SWITCH, THE TEMP SWITCH NOT DOING THE WORK OF THE FAN SWITCH/SENSOR. REPLACE FAN SWITCH
Replace coolent sensor.
Already replaced. I was having an overheating problem all around. Replaced fans radiator water pump and coolant sensor on top of thermostat. Fans weren't engaging so I called Chevy dealership and told them the same thing. I found out I had air in my system that was preventing my fans from working properly. Bleeder valve on top of thermostat.
