I had a look from the scuttle panel side today, and from there it was pretty obvious what was happening. The impeller was catching on the end of its housing, hence why it hasn't made a noise since I've been driving round with it undone. Everytime I pushed the whole lot from the inside (as if it was screwed in again) it made that noise, so it appears that the impeller had slid down the shaft it sits on somehow and was catching on the end. My dad tried to push it back up the shaft but he said it didn't move, but it doesn't make that squeaking noise now, even screwed in.
Fingers crossed!
