Kenworth T700 Fan Blades & Shrouds

Frequently Asked Questions About Kenworth T700 Fan Blades & Shrouds

What is the difference between a fan blade and a fan shroud?

The fan blade is the rotating component that pulls air through the radiator and charge air cooler to keep engine temperatures in check, while the fan shroud is the stationary housing that surrounds the blade. The shroud directs airflow efficiently across the radiator core and prevents air from recirculating around the sides of the fan, which helps the cooling system work as intended.

How do I know if a fan blade or shroud will fit my Kenworth T700?

Fit depends on factors such as engine model, radiator size, fan diameter, blade pitch, and mounting configuration, all of which can vary by build year and spec. Before ordering, check your truck's existing part number or measure your current blade and shroud dimensions, and compare them against the listed specifications on each product page. If you are unsure, contact our parts team with your VIN or engine details so we can confirm compatibility.

What are fan blades typically made of, and does material affect performance?

Fan blades for the T700 are commonly made from molded plastic composite or nylon, materials chosen for their durability, resistance to heat, and lighter weight compared to metal. Shrouds are often made from durable plastic as well, designed to hold up under engine bay temperatures and vibration while maintaining proper airflow direction.

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

Many experienced truck owners replace fan blades and shrouds themselves, since the job generally involves accessing the front of the engine, removing the old component, and bolting in the replacement. However, because the fan is located near moving belts and the radiator, and torque specs matter for blade balance and safety, we recommend having the work done by someone comfortable with engine bay repairs or a qualified technician if you are not experienced with this type of job.

Why is my fan blade or shroud making noise or causing overheating issues?

Unusual noise can point to a cracked or unbalanced blade, a loose fan clutch, or a shroud that has shifted out of position and is rubbing against the blade. Overheating issues are often related to a damaged shroud that no longer directs airflow properly across the radiator, or a blade that is worn, warped, or missing pieces. Inspecting both components for cracks, warping, or missing mounting hardware is a good first step before deciding whether a replacement is needed.
