Frequently Asked Questions About Peterbilt 362 CAC Clamps, Boots & Hoses
What size CAC boots and clamps do I need for my Peterbilt 362?
Most Peterbilt 362 models require 3.5" to 4" diameter CAC boots and corresponding T-bolt clamps for the charge air cooler connections. However, sizes can vary based on your engine model and turbo setup. We recommend measuring your existing connections or checking your engine specifications. Common sizes include 3.5" for inlet connections and 4" for outlet connections on CAT C15 and Cummins ISX engines.
How do I know when my CAC boots need replacement?
Replace your CAC boots if you notice any of these signs: visible cracks or splits in the rubber, oil residue around connections, hissing sounds under acceleration, loss of boost pressure, or poor fuel economy. Soft or swollen boots also indicate deterioration. Most drivers report needing replacement every 3-5 years depending on operating conditions, with high-heat applications requiring more frequent changes.
What's the difference between standard and silicone CAC hoses?
Silicone CAC hoses offer superior heat resistance (up to 500?F), longer lifespan (typically 2-3 times longer than rubber), and better flexibility in cold weather. Standard EPDM rubber hoses are more economical but typically handle temperatures up to 300?F. For heavy-duty applications or extreme climates, silicone is worth the investment. Both types work with standard T-bolt clamps.
Can I install CAC components myself or do I need special tools?
CAC boot and hose replacement is a straightforward DIY job requiring basic hand tools: a socket set for T-bolt clamps (typically 10mm or 7/16"), flat-head screwdriver for positioning, and optionally some dish soap for easier installation. Most drivers complete the job in 30-45 minutes. Ensure the engine is cool before starting, and always torque T-bolt clamps to 75-85 inch-pounds to prevent leaks without damaging the boot.
Why do my CAC clamps keep coming loose?
Loose clamps typically result from improper torque, worn clamp threads, or mismatched component sizes. Always use constant-torque clamps for CAC applications as they maintain pressure despite temperature changes. Standard clamps can loosen due to thermal cycling. Check that your boots aren't oversized for the pipes, and replace any clamps with stripped threads. Many drivers also apply a thin layer of RTV sealant on the pipe before installing boots for extra security.
