No No No wd 40 is slippery. They make a product called belt dressing you can use. I would make sure the pulleys that the belt runs on are not going bad and dragging ---

If the belts are more than 4 years old I would go ahead and replace them. Use a high quality belt like Goodyear Poly-V or Gates. I have a 2000 Blazer that even with a brand new belt (Dayco) is very noisy. The Goodyear Poly-V is the only belt that works on the Blazer. I’ve used belt dressing in the past, it is a temporary fix and makes a mess of the engine compartment. I prefer just to replace the belt(s) instead. Ed B.
