cooling fan ghost V70-XC70 2001

we recently bought a 2001 V70 T5 from a private party.
Is it normal that the cooling fan comes on, even sometimes an hour after we put the car in the garage ?
It seems OK with me, but my wife is wondering.

    This is normal. Look in your owners manual. From page 43:

    "Approximately 50 minutes after the ignition is turned off, the blower may come on automatically, and run for five minutes, to remove condensation in the A/C evaporator."

    Freaked me out the first time it happened also. It's pretty loud!

    * * * RECALL * * * V70-XC70 2001

    posted by  someone claiming to be Niel on  Wed Sep 15 21:14 CST 2004 [RELATED]

    Days ago there was a recall for S60, V70, and XC70 models built in 2000 and 2001. See http://www.flexiweb.co.nz/volvoforum/viewtopic.php?t=179 and the link from that forum post. Fans are being replaced for free worldwide as a precausion against a small possibility of sparks and engine overheating.

    Have fun...

    (I've got a '71 144 and '88 240, sold the '84 760, and hope to get a 850 wagon or V70 soon to replace the 240)

    Engine cooling fan under hood; normal for this fan to continue running for a few minutes after shutting down a hot engine. If this fan is running an hour later, there is a problem and should be checked out.
    Climate control fan inside cabin; If the A/C has run for at least five minutes, then this fan will start and run at full speed for five min. aprox 50 minutes after engine shutdown to dry out the A/C evaporator and prevent mold/mildew from forming. It is called "afterblow", and if you search, there is a sentence or 2 about it in the owners manual.

    I have an S60 2001. Next time when the cooling fan comes on, go into the car and see if the air-cond is blowing. Mine comes on once in a while. Enquired with an 'expert' and he said that this is normal. On my car, it is claimed that there is a system that works like a "dryer". Humidity is created on the 'pollen filter' once the AC has been used and then switched off. This fan comes on to get it dried, so that there will not be a humidity "smell".
    But this is an optional system, if you do not want this system, an authorised Volvo dealer can switch the function "off" easily by diagnostic computer (called VADIS). But have been recommended you to leave it "on"

      My 01 V70 T5 does exactly this once in awhile (engine fan on followed by interior fan(not sure if AC) on for quiet awhile). Live in Seattle so it doesn't get super hot often.

      I found that if you just turn the key to accessory power position and back, the interior fan will go off for good. Thanks for the post. Now I know what is actually going on and leave it alone next time :-)

    Unusual but possible V70-XC70 2001

    posted by  someone claiming to be cn on  Tue Sep 14 12:40 CST 2004 [RELATED]

    Cooling fanb is triggered by temperature sensor(s), which measures either coolant temp or air temp.

    If temp is high, the fan is ON.

    In HOT weather, if car has been running and parked in garage fan, if ever comes on, will be on while the car is driven into garage.

    It is unusual for fan to be on an hour later.

    have it checked.

    cn
