Hey guys, here's the concern, i have this Jetta since 1 week. Everything is great and every equipment's working.

This afternoon, i drove to work, heat is working and hot.(same for all week)
Tonight, i leave work, drive at a normal speed, then, beep-beep-beep....High temp warning comes up, the temperature went up like crazy.
I stoped on the shoulder, look under the hood, nothing, no leak, coolant seem ok. but the Rad. Fan doesn't seem to run.....


Any idea anyone???

Thanks
