squealing cooling fans

Postby ppete100 » Mon 26.03.2012, 21:28

cooling fans started making a squealing noise lately, is there anyway to lubricate them or are they on their way out? :?

Hi, I noticed your question as I have a similar issue.
Did you work out a solution?
Thanks

Drill a very small hole in the tit on the backplate and syringe a couple of drops of thin oil in to lubricate the bearing.

And after you've done that, and hopefully lost the squeak, remember to let your engine get hot and check that both fans kick in when the needle on the temp gauge is approx. at the 3/4 mark :wink:

Been busy doing Luther things, but got round to looking at this issue today, and to my surprise there was already a drilled hole in the tit of the casing....good because it's easy for me to just add the oil, the bad thing is that it was a problem prior to me getting the car!
Fingers crossed it will work

Yes, be patient. give it a couple more drops of light oil and work it by shorting the sender wire.

Old fans are Renault OEM or Kenlowe and balanced, new generic fans are Chinese and not balanced.

Thanks...will be patient and try some more lube and see how it goes...if not SJ sell a replacement fan....not OEM by the looks of it....Strange is selling a second hander on ebay...OEM version but difficult to know if it's ok.
Thoughts?
