The drive belt idler pulley works in conjunction with the tensioner pulley/tensioner assembly to maintain tension on the belt as well as guide the belt. Idler pulleys are also used to achieve ideal belt routing around the engine drive accessories such as the power steering pump, water pump, A/C compressor, and alternator.

The idler pulley is an often overlooked maintenance item but it is just as important as the belt tensioner itself. In most cases it is recommended to replace the idler pulley at the same time as the belt tensioner.

Very nice

This shirt is very cute. Looks great on my fiancé and is very high-quality. It fits him well. It’s not too thick. I love the color. We got the green one.

Nice shirt for the price
Color: White, Size: Large
Good quality shirt, especially for the price. Drapes nicely, almost a painterly feel with the fabric. Works across the wardrobe spectrum, pairing well with slacks in a business setting or with chinos for a more casual look.

Great Fit and Price While Updating My Wardrobe
Color: Shortbread, Size: Large
As I’ve been getting fitter, my old clothes started looking too baggy, so I needed something that fit better without breaking the bank. This COOFANDY chambray shirt turned out to be exactly what I was looking for—lightweight, wrinkle-resistant, and stylish enough for casual or dressy wear. The fabric feels soft and breathable, and it pairs easily with jeans or slacks. Since I’m still losing weight, I didn’t want to overspend on clothes I may size out of soon, and these hit the sweet spot for both quality and affordability.
