Peterbilt 367 Fan Blades & Shrouds

Frequently Asked Questions About Peterbilt 367 Fan Blades & Shrouds

How do I know if a fan blade or shroud will fit my Peterbilt 367?

Fit depends on your truck's engine model, cooling system configuration, and the diameter and blade count of the original fan. Before ordering, check your existing fan blade's diameter, pitch, and mounting hole pattern, as well as your shroud's dimensions and mounting points, and compare them to the specifications listed on each product page. If you are unsure, our team can help you confirm compatibility using your VIN or engine details.

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

Fan blades are typically molded from heavy-duty plastic or composite materials designed to withstand constant airflow, heat, and vibration under the hood, while shrouds are usually made from durable plastic or steel depending on the application. These materials are chosen for long service life in demanding on-road and vocational use, but like any wear component, they should be inspected periodically for cracks, chips, or warping.

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

Many experienced truck owners and shop technicians replace fan blades and shrouds themselves, since the process generally involves removing the old component, checking clearance around the radiator and belt system, and securing the new part with the appropriate hardware. However, because the fan is located near moving belts and pulleys, proper safety precautions and torque specifications should be followed, and if you are not comfortable working around the engine cooling system, having a qualified technician handle the installation is a good option.

Why is my fan blade or shroud cracked, warped, or making noise, and will a replacement fix it?

Cracking, warping, or unusual noise is often caused by age, heat exposure, debris impact, or a shroud rubbing against the fan due to engine mount wear or misalignment. Replacing a damaged blade or shroud will typically resolve the immediate issue, but if the noise or damage returns quickly, it is worth having your engine mounts, fan clutch, and belt alignment inspected to rule out an underlying cause.

Do these fan blades and shrouds meet OEM specifications for the Peterbilt 367?

We offer both OEM and quality aftermarket options for Peterbilt 367 fan blades and shrouds, and each product listing notes whether the part is OEM or aftermarket along with relevant fitment details. Aftermarket parts are manufactured to match the fit and function of the original equipment, but we recommend reviewing the listed specifications or contacting us if you need a part that matches a specific OEM part number.
