How To Change Idler Pulley On Ford F150

A bad pulley can be very annoying and with pretty much your engine hard to diagnose. Symptoms will begin with a rattling or rattling sound as the engine heats up and eventually progress to always making that sound. Fortunately, these parts aren’t terribly expensive, and replacing them is relatively easy. So if you have extra money, you shouldn’t replace them all at once. The tensioner will cost around $40 to $50 depending on where you buy it and shipping costs. Idling pulleys cost between $15 and $30. A zigzag belt can cost anywhere from $35 to $50 depending on the brand of belt you’re buying. If you take it to the store, it will cost you another hundred dollars to install.

Step 1 – Access to the pulleys

Depending on your engine bay layout, you may find you’ll need to remove some pieces to make room for the pulleys and belts. In most cases, you just need to remove the air intake manifold running over the shroud. This is usually held in place with a 10mm bolt or with a wire clamp that can be loosened with a flat head.Figure 1. Remove the black plastic snorkel on top of the engine.
