Hi, I have a squealing noise from one of my belts when I start the car and when it is cold out (it seems). The belts are almost new, replaced August 2017. It is not the timing belt, new too. Any ideas, lube or quick fix?

A friend, who is a former mechanic drove with me yesterday and said to: "Use soap and lube the belt"?

Lubing the belt would only work for a brief period of time. What you need to check would be the belt tension-er. If it is weak, it would slip when starting as the engine would be accelerating from zero rpm, resulting in the noise. Other thing to note would be the serpentine belt, is it of the correct size?
