Frequently Asked Questions About International S2100-S2300 CAC Clamps, Boots-Hoses

What years and specific International truck models are these CAC components compatible with?

These charge air cooler (CAC) clamps, boots, and hoses are designed specifically for International S2100 and S2300 Series trucks manufactured from 1989 through 2001. They fit trucks equipped with Caterpillar 3406, C12, and C15 engines, as well as Cummins ISX and N14 engines. Always verify your engine model and year before ordering, as some mid-year production changes may affect fitment.

What material are these CAC boots and hoses made from, and how long do they typically last?

Our CAC boots and hoses are constructed from multi-ply reinforced silicone or heavy-duty EPDM rubber, depending on the specific part. These materials are rated for temperatures ranging from -65?F to 500?F and pressures up to 100 PSI. Under normal operating conditions, you can expect 3-5 years of service life. Silicone options typically last longer than standard rubber but come at a higher price point.

Do I need special tools to install these CAC components, and how difficult is the installation?

Installation typically requires basic hand tools including various socket sizes, screwdrivers, and pliers. Most experienced mechanics can complete a boot or hose replacement in 30-45 minutes. The main challenge is accessing tight spaces around the charge air cooler. We recommend having a pick tool for removing old clamps and applying a thin layer of silicone spray to ease boot installation. No special diagnostic equipment is needed.

How do I know if I need T-bolt clamps versus constant torque clamps for my application?

T-bolt clamps are ideal for applications where you need maximum clamping force and don't mind periodic retightening. Constant torque clamps automatically adjust for thermal expansion and contraction, making them better for set-and-forget installations. For CAC connections that see frequent temperature cycling, constant torque clamps reduce maintenance needs. Most OEM applications originally used constant torque clamps, but many drivers successfully use T-bolt clamps as a more economical replacement option.

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

Common indicators include visible cracks or bulging in boots, oil residue around connection points, whistling sounds under acceleration, reduced turbo boost pressure, and black smoke from the exhaust. During inspection, look for soft spots in hoses, loose clamps that won't hold torque, and any signs of rubbing or chafing. If you notice a sudden drop in fuel economy or sluggish acceleration, check your CAC connections first as these are often the culprit.
