Goodyear Belts & Hoses 58147 Idler Pulley Steel 3.3 in. OD Serpentine Belt Drive

The Goodyear Belts & Hoses 58147 Idler Pulley (also called an accessory drive belt idler pulley or FEAD pulley) guides the serpentine belt in your engine's belt drive system. Idler pulleys help keep the belt routed and aligned as it carries power from the crankshaft to the engine accessories.

Key Features:

• Steel pulley construction that stands up to heat and the conditions in the engine compartment
• 3.3 in. outside diameter
• Black finish
• For serpentine belt drive systems
• Sealed ball bearings protect against contaminants and help the bearing last longer
• Precision-machined for proper belt seating and smooth, vibration-free belt travel
• OEM-performance grade, built to meet or exceed OEM specifications

A worn idler pulley bearing can cause noise, belt wear and misalignment. Replacing it helps restore smooth, quiet belt operation and protects the rest of the accessory drive.
