Frequently Asked Questions About Kenworth T700 Fan Blades & Shrouds
What year models of Kenworth T700 are these fan blades and shrouds compatible with?
Most aftermarket fan blades and shrouds for the Kenworth T700 are designed to fit models from 2010 to 2019. However, compatibility can vary based on your specific engine configuration (ISX, DD15, or MX-13). Always verify your engine model and cooling package specifications before ordering. Pre-2010 models may require different mounting brackets due to changes in the radiator design.
Are aftermarket fan blades as durable as OEM parts, and what materials should I look for?
Quality aftermarket fan blades are typically made from reinforced nylon composite or glass-filled polyamide, which offers comparable durability to OEM parts. Look for blades with UV-resistant coating to prevent cracking and warping. Avoid cheaper plastic options that may become brittle in extreme temperatures. For shrouds, heavy-duty fiberglass or ABS plastic construction provides the best longevity and resistance to vibration-related stress cracks.
How difficult is it to install a replacement fan blade and shroud, and what tools will I need?
Installation typically takes 2-3 hours for experienced mechanics. You'll need basic hand tools including socket sets (typically 10mm-19mm), torque wrench, and potentially a fan clutch wrench. The most challenging aspect is often accessing the lower mounting bolts and properly aligning the shroud with existing brackets. Some installations may require removing the radiator hoses or intercooler pipes for clearance. Professional installation is recommended if you're not comfortable working around the cooling system.
What's the difference between 9-blade and 11-blade fan options, and which is better for my truck?
9-blade fans typically move more air at lower RPMs and are quieter, making them ideal for highway driving and fuel efficiency. 11-blade fans provide better cooling capacity for heavy-load applications, stop-and-go driving, or trucks operating in extreme heat. The trade-off is slightly higher noise levels and marginal fuel consumption increase. Match your selection to your typical driving conditions and load requirements.
Why is proper fan blade to shroud clearance critical, and what spacing should I maintain?
Incorrect clearance can cause blade strikes, reduced cooling efficiency, and premature component failure. Maintain 0.75 to 1 inch clearance between the blade tips and shroud opening on all sides. Too much clearance reduces airflow efficiency by up to 30%, while too little risks catastrophic blade damage. Always check clearance after installation by manually rotating the fan and measuring at multiple points around the shroud.
