A customer has a 2002 Toyota Sequoia that needs an idler pulley, and all of the parts that I have looked up have grooves. But the customer’s part is smooth with one lip on each side. What’s the deal?

That is very common in our parts world. However, the manufacturer you use should have a spec book that you can measure the old pulley and find something that can be used. The lip on each side is not necessary for most vehicles because the tensioner pulley will keep the belt from moving around.
