I was dinking in the car the other morning and had the key on, 2 pushes of the start button without the brake applied, motor off, not started. I observed something; this was in the morning and fairly cold out; around 50 degrees. The radiator fans, both of them kicked on then off, then on again over and over. I'd say they were on at least 3X as long as the off cycle; maybe 30 seconds on, 10 seconds off, repeat. Has anyone else observed this and more important, is it supposed to do this? It was as if the motor was still warm after a drive and had not cooled the block enough to open a thermstat or something.
