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.

Brighten up the dark wild
Color: 52Inch Lights +LED Pods+ Wiring Harness
My jeep came with a worn out set of these. In the big picture they were an easy replacement and allowed me to clean up the wiring mess in the jeep. The downside is they are terribly noisy driving down the road. They make great light in the dark wilderness. As soon as I'm ready for some paint correction they will be coming off.

Super Bright and Easy to Install!
Color: 52Inch Lights +LED Pods+ Wiring Harness
The Nilight ZH023 LED Light Bar Combo is outstanding! The 52-inch bar plus the two 4-inch fog lights put out an incredible amount of light—perfect for off-road driving at night. The spot and flood combo gives great distance and wide coverage, and the wiring harness made installation simple. Everything feels durable, weatherproof, and built to last. For the price and performance, this is one of the best lighting upgrades you can get for your vehicle.

very bright
Color: 52Inch Lights +LED Pods+ Wiring Harness
It fit my 2015 f150, but I had to extend the power cable because my battery is on the passenger side, not the driver's. I also wish it came with instructions in the box rather than on the Amazon listing.
