My car usually does that after I go for a long drive and shut off the car for a short period of time, then turn it back on.

So this is normal? Odd that I haven't noticed it over the last 5 years....why would the fan run at such a high rpm at start up as in what is the purpose behind it? Also, why does it not stop until I shut down the vehicle and then start it back up again?

Update- so fan replaced...not cheap. Fan is not as loud, however, still coming on high at start. most of the time it goes away but today it stayed on high for a couple miles so i pulled over shut it down and started back up and it was gone.
thermostat sensor? water pump going? im kinda of upset that i had to pay so much for the fan and it wasnt really the source of the problem. |

I think you're going to continue to waste money on this. Most of our cars have this happen often as was stated by at least 3 different people in this thread.

yea its pretty normal on some of our cars. it is annoying though.
you should go to autozone, get them to look for codes, its free. waterpump you would have known about by now, car would have shut off. thermostat will fail open, and leave a code without notifying on your dash at all. my fan is loud as shit when the AC is on and it is hot out. if it isnt hot out, then the fan wont kick in. |

just to recap- I already did the autozone thing as suggested previously...no codes. This is happening at start up with the engine cold and that is why it is not making any sense at all.

I had the maintenance plan to 100K so i did the CBS stuff as called for at the dealership up to then, nothing special leading up to 100K.
After 100K and out of pocket... i did the rear brakes and rotors. I flushed the engine coolant just after 100K. Changed power steering fluid at the same time. I am going to flush brake fluid and bleed when i get some free time this month. Oil and filter changes on CBS schedule and an extra one in between, so about every 7000 miles. Air filter and MAF cleaner done at 120K. ATF is original, i am on the wall about whether i should mess with it now or leave it since i am passed the window of opportunity. I will do rear diff fluid soon. |

I hear ya about the ATF fluid that is something that concerns me as well. Have you thought about replacing your water pump before it fails?
Back to my high running fan at startup. Isn't it odd that it runs high when engine is cold? |

is it doing it even with the AC compressor off. maybe you could try leaving your AC compressor off before you startup and see if it stills does it. |
