Frequently Asked Questions About Ford LTA / LTL 9000 CAC Clamps, Boots & Hoses

What years and models are these CAC components compatible with?

These charge air cooler clamps, boots, and hoses are designed specifically for Ford LTA 9000 and LTL 9000 models from 1976 through 1997. They fit both single and tandem axle configurations. Always verify your engine model (Caterpillar 3406, Cummins N14, or Detroit Series 60) as different engines may require different hose diameters and boot configurations.

How do I know what size CAC hose or clamp I need?

Measure the outside diameter of your existing CAC pipes where the hose connects. Common sizes are 3.5", 4", and 5" diameter. For clamps, add 1/4" to your hose outer diameter to ensure proper fit. If replacing boots, check for stepped or straight configurations - stepped boots typically go from 4" to 5" or 3.5" to 4". The part numbers on your existing components can also help identify the correct size.

Are silicone hoses worth the extra cost over standard rubber?

Silicone CAC hoses typically last 3-4 times longer than standard rubber hoses and can withstand temperatures up to 500 degrees Fahrenheit compared to 250 degrees for rubber. They resist oil contamination better and maintain flexibility in extreme cold. While silicone costs 40-60% more upfront, most drivers report fewer roadside failures and replacement intervals extending from 2 years to 6-8 years.

What are the most common installation problems and how do I avoid them?

The biggest issues are: 1) Not cleaning pipe ends thoroughly - use emery cloth to remove rust and old adhesive. 2) Over-tightening clamps which can cut into hoses - torque T-bolt clamps to 50-60 inch-pounds only. 3) Twisting hoses during installation - use a silicone spray lubricant and push straight on. 4) Reusing old clamps - always replace clamps when replacing hoses as old clamps lose tension and cause boost leaks.

How can I tell if my CAC boots and hoses are failing before they blow out?

Check for these warning signs during pre-trip inspections: soft spots or bubbles in hoses indicating internal delamination, oily residue on the outside from interior degradation, cracks at the bends of boots, loose clamps that constantly need retightening, and boost pressure dropping below normal operating range. Any black soot around connections indicates exhaust leaks that will quickly destroy rubber components.
