I got a coolant flush and refill tonight and noticed at the stop lights my twin fans were on hyperdrive mode (full speed), but you're probably wondering, "well, that is normal..."

IT WON'T SHUT OFF!! I mean, I turn the key and yes it of course shuts off, but man it won't stay out of high speed mode.

Is this weird?

- I checked the levels they're fine.
- It's +4 out (38 degrees USA)
- Temp gauge reads just below half way mark.
- Bottle of redline water wetter added @ fill.

TIA

 

Is AC on?
Reset the ecu?
Check the wiring harness?
Long shot, but try burping any air that may still be in the loop.

 

Ya, it sat overnight and I'll see if it still does it today. It goes in to Nissan anyways this Friday.

I did burp the lines when I changed the coolant. It's blowing warm air all the time so I know it's working properly. Strange I say!
