Frequently Asked Questions About Ford F650-F750 Truck CAC Clamps, Boots & Hoses

What years and models are these CAC components compatible with?

Our CAC clamps, boots, and hoses are designed to fit Ford F650 and F750 trucks from 2000 through current model years. However, there are variations between different engine options (6.7L PowerStroke, 7.3L, Cummins ISB) and whether your truck has an intercooler or aftercooler setup. Always verify your specific engine configuration before ordering, as CAC routing can differ between vocational and straight truck applications.

What are the signs that my CAC boots or hoses need replacement?

Common indicators include boost pressure loss, black soot around connection points, visible cracks or tears in the rubber, collapsed hoses under boost, and increased turbo lag. Many drivers also report hearing a whistling sound under acceleration or seeing higher EGTs due to inefficient air delivery. If your truck feels sluggish or you're getting poor fuel economy, inspecting your CAC components should be a priority.

Are silicone hoses worth the extra cost over standard rubber?

Silicone hoses typically last 3-4 times longer than standard rubber, especially in high-heat applications common in F650/F750 trucks. They resist oil contamination better and maintain flexibility in extreme temperatures ranging from -65?F to 500?F. While the initial investment is higher, most fleet operators find the reduced downtime and replacement frequency make silicone the more economical choice for trucks seeing heavy use or extreme conditions.

What size clamps do I need and can I reuse my old ones?

CAC hose diameters on F650/F750 trucks typically range from 3" to 4" depending on your engine and model year. We recommend replacing clamps when changing hoses, as old clamps may have lost tension or developed corrosion. T-bolt clamps provide more uniform pressure than worm-gear clamps and are preferred for high-boost applications. Always measure your existing hose OD to ensure proper clamp sizing, as aftermarket modifications may have changed stock dimensions.

How difficult is installation and what tools are required?

Installation typically takes 1-2 hours for someone with basic mechanical skills. You'll need standard hand tools, including various socket sizes, screwdrivers, and potentially hose picks for stubborn connections. Access can be challenging on certain model years, particularly around the intercooler connections. Many technicians recommend using a silicone spray lubricant during installation to ease hose fitment. Some applications may require removing the air filter housing or other components for access.
