Squeak on start up.

[jam1991]

When starting and whilst letting it heat up. The belt on the left side of engine bay (presuming alternator belt correct me if im wrong) was squeaking slightly.

Soon stops however, is there anything I can do to help stop this, WD40 on the belt?

Thanks

Im not sure if its auto tensioner but i'd imagine so...

If not just adjust it, if so then replace the belt.


Be warned small possibility it could be a bearing in the alternator, idler etc.
