i just changed out my coolant.

followed the steps in the owners manual

drain
put bleeder bolt + drain plug back in

fill up to filler neck

bleeder bolt (no bubbles came out BTW it was already a steady stream)

then I tightened that back in

started the car up for at least 30min and heres the problem

problem >>>> radiator fan never turned on not even once!

what should i look for ...i suppose fuse or something right?

// my car didn't over heat
// no other signs of over heating
// a little smoke came out the back but thats normal
// its sorta of cold here in SF i think 40-50 degrees idk if that matters

Just had the same problem today. That, and my bottom radiator hose was flat. I will be waiting to see the answers to this.

Did the temp needle go past about 1/2 way? Did the car sit idling for 30 mins or did the motor see any RPM's?

If it is 40-50°F and the car is idling, the fan may not need to kick on. The ECU only kicks the fan on when needed.

might want to check your temp sensor at the t stat as if the sensor fails, fan doesn't turn on as well. Or try jumping the fan to see if it work at all.
