Overview
The Crown Automotive 53010309 is a smooth fan pulley that mounts to the water pump on 4.0L 6 cylinder engines. It has a 4.57-inch diameter. Crown Automotive describes its parts as replacements for Jeep vehicles, and this pulley is listed among its water pump accessories.
The fitment is the 4.0L 6 cylinder engine with water pump mounting. Confirm fit for your vehicle’s year, model and trim before ordering, and check the pulley diameter against your existing pulley.
Key features
- Mounts to the water pump
- Smooth pulley face
- 4.57-inch diameter
- Fits 4.0L 6 cylinder engines
Belt and pulley alignment
A fan pulley turns with the drive belt, so its face must line up with the other pulleys on the belt path. A pulley that sits off line wears the belt edges and can cause squeal or early belt failure. Spin the pulley by hand after mounting and watch for wobble, roughness or side play that suggests worn bearings.
Pulley wear usually shows as a rough or grooved face, noise from the water pump area, or a belt that rides to one side. When replacing the pulley, inspect the belt, tensioner and water pump mounting bolts at the same time, since they work together and are often worn from the same heat and vibration.
- Check the belt for edge wear after installing
- Spin the pulley by hand and listen for roughness
- Inspect the tensioner and idler pulleys
- Tighten mounting bolts to specification after the first drive
