Why does the fan run after the ignition is off?
If the fluid is good, there may be another issue in your cooling system and hopefully it is minor. The fan running after the ignition is off is just a reaction to the higher temperature of the engine, it is normal for the fan to run after the ignition is off if the engine temperature is too high.
When do your fans stay on when you turn them off?
It even does it on cold days in the middle of February, but the temp gauge never goes above halfway….hmm. It’s rather embarrassing when you get out of your car at school, work, or at a store, lock and proceed to walk away from your car and people say “hey man, your car is still running”.
Why does my car’s temp gauge keep going up?
Not knowing if the sender is reliable it defaults to fans on, in order to prevent a possible over heat. Change the T-stat. and while you are there change the sending unit as well.
What does it mean when your car fans keep running?
When the cooling fans are stuck always running then typically it means that the ECU is not detecting the engine coolant temperature (ECT) sensor or something thereabouts. When the ECU doesn’t know the true temperature is just goes into fail-safe mode and keeps the fans running.
What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
When do you turn on the fan relay?
When the correct parameters are met, a temperature switch or the computer will activate the relay, which will allow power to the fans. The relay will usually be activated once it is detected that the vehicle’s temperature approaches excessively high temperatures.
When to turn off radiator fans in Silverado?
2 stage oul pump and when warm you can see much lower pressure so you are good. 10 months later… My 2015 Silverado 6.2L Z71 Off Road LTZ just started with the fans running all the time when driving. The engine temp is good at 260, the fans shut off 5-10 seconds after I turn off the engine.
Why does the ECT gauge default to cold?
When the DTC sets the engine did not reach a predetermined temp in a calculated time. Fans default on and ECT gauge defaults cold. Replaced water pump and coolant. They referenced a code P0128. Bill came to over $700. Seems to have fixed the issue.
