I have a 2014 chevy silverado 1500 5.3l that i am having a issue with the cooling fans running on high occasionally. when this happens my temp gauge will read zero and when i kill the engine the fans stay on. the only way to shut them off is to crank the engine and shut it right back off. i have been through two temp sensors and still have the.

Bad fan relay. you happen to possess a 2014 chevy silverado and observe that the radiator fan persists in running. the first thing you should check is your fan relay. a defective fan relay may be the culprit. the role of the fan relay is to function as a switch that activates or deactivates the cooling process. it will depend on the engine. The fan in your truck has an electronically controlled viscous clutch. there's always a little drag inside so the fan always spins a bit, usually between 3 and 500 rpm going down the road. when the ecm sees coolant temps getting up beyond 200f it will start to slowly engage the fan bit by bit, with full engagement happening around 207 212f. 2015 gmc sierra 5.3. the other day i noticed my radiator fans constantly running at full blast and staying on for 5 minutes after shutdown saw that the coolant temp gauge was pegged low. i replaced the coolant temp sensor and the problem is still there. looking at the live data on my obdii scanner, i can see that the coolant temp is reporting.
Why Is My Radiator Fan Constantly Running The fan in your truck has an electronically controlled viscous clutch. there's always a little drag inside so the fan always spins a bit, usually between 3 and 500 rpm going down the road. when the ecm sees coolant temps getting up beyond 200f it will start to slowly engage the fan bit by bit, with full engagement happening around 207 212f. 2015 gmc sierra 5.3. the other day i noticed my radiator fans constantly running at full blast and staying on for 5 minutes after shutdown saw that the coolant temp gauge was pegged low. i replaced the coolant temp sensor and the problem is still there. looking at the live data on my obdii scanner, i can see that the coolant temp is reporting. So the fan on engine off will start at 225 degrees water temp and will run for 300 seconds. if your engine is off, like not even in accessory on, and the fan runs for more than 300 seconds then there is one of two problems: 1) there is a temp sensor failure or bcm hiccup. 2) your water temp is over 254 and it’s in emergency mode. 2015 chevy silverado 5.3 v8 (lt trim i think) issue: radiator fans stay on as long as the truck is running. initial diagnosis: my research lead me down the coolant sensor (which i replaced) and the thermostat path (which i was about to replace but didn't).
