Peterbilt 567/579 Fan Blades & Shrouds

Frequently Asked Questions About Peterbilt 567/579 Fan Blades & Shrouds

How do I know if a fan blade or shroud will fit my Peterbilt 567 or 579?

Fan blades and shrouds vary by engine make, cooling package, and cab configuration, so fitment is not universal across all 567 or 579 trucks. Before ordering, check your truck's VIN, engine model, and OEM part number against the product listing specifications, or contact our parts team to confirm compatibility.

What material are these fan blades and shrouds made from, and how durable are they?

Fan blades are typically molded from high-strength composite or reinforced plastic designed to handle constant airflow, heat, and vibration under the hood. Shrouds are generally made from durable plastic or composite material built to direct airflow efficiently while resisting cracking from engine heat and road debris over time.

Can I install a new fan blade or shroud myself, or do I need a professional?

Many owner-operators and shop technicians replace fan blades and shrouds themselves, as the job generally involves removing the shroud, disconnecting the fan clutch or hub, and swapping in the new component. However, because incorrect fan blade balance or clearance can lead to noise, vibration, or contact with the radiator, we recommend having the installation checked by a qualified diesel technician if you are unsure.

Will a replacement fan blade or shroud affect my truck's cooling performance?

A properly fitted fan blade and shroud are important for maintaining correct airflow across the radiator and engine bay. Using a part designed for your specific truck configuration helps preserve intended cooling performance, while mismatched or damaged components can reduce airflow efficiency and lead to overheating issues.

How do I know if my current fan blade or shroud needs to be replaced?

Common signs include visible cracks, missing or bent blades, excessive vibration, unusual noise from the engine bay, or a shroud that no longer sits securely around the fan. If you notice any of these issues, it is a good idea to inspect the components closely and replace them before they cause further damage to the radiator or fan clutch.
