Mouser 10 Posted February 18, 2014 Afternoon gents, My radiator fan that comes on when stopped is now making loads of noise, ive looked, and it appears to be a 'rubber seal'or O-ring on the centre of the fan come loose, so im assuming its running dry, which is grim. I've taken a video for those who really need to see/hear it, but i'd have to make an account on a vid host website, but you can see the ring is loose. If you're leaning under the bonnet, it's on the fan on your right. I'm useless under the bonnet but have the funds. Should it not be driven? Quote Share this post Link to post Share on other sites
