Noisy fan 700

My Australian 1988 model 740 has a noisy heater/airconditioning fan. It sometimes howls very loudly, other times it is fairly quiet. I guess the bearing or bushes in the fan are worn out. A new fan from Volvo would probably be quite expensive. Is it possible to repair the fan by fitting new bearings/bushes, or to replace it with one from another make of car. I heard that in the case of 240 series you could replace the fan with one from a Holden Commodore. So I wonder whether a similiar repiar is possible with the 740.

    No drama mate,

    I have been sucessful (running for 1-1/2 years now) in lubricating a fan that was noisy. I removed, sprayed down with WD-40 (don't know if you have that their mate). Oil bushing (bearing - whatever) with regular oil then, it you can get to them.

    Just remember, when you turn the fan on it will throw oil, so stick in a box, connect it and run it to spin off oil before re-installing. You'll smell WD40 for a few days, but then should go away.

    I was down under a year ago last October and November in Melbourne. Didn't see alot of Volvo's, but did see one dealership. Seems that Ausi's I worked with liked the bloody Toyota trucks with the flat beds and hugh Kanga bopping bumpers. Then there are the Ford Fairlanes and, as you mentioned Holdens (GM).

    Must say though, you guys are always looking for a reason to party and gamble (was there during race that stops the nation and rugby quarter finals).

    While the bushing is probably worn, you might try lubricating it with a good motor oil to see if that helps. See the 700/900 FAQ for tips on fan replacement using a GM generic fan. Siemens sells a near drop-in replacement as well, found through aftermarket parts places.

    I don't think you guys down under were ever blessed with the Chevrolet Citation; the cheaper fan listed for it is a perfect fit for the 740's. Check the FAQ's on this site for more info.
