Frequently Asked Questions About Peterbilt 387 Charge Air Coolers

What years and engine models are these charge air coolers compatible with?

Our Peterbilt 387 charge air coolers are designed to fit models from 2000-2010. They're compatible with most common engine configurations including Caterpillar C12, C13, and C15, Cummins ISX and N14, and Detroit Series 60. Always verify your specific engine model and serial number before ordering, as some mid-year production changes may affect fitment. Check the radiator support measurements and inlet/outlet pipe diameters to ensure proper compatibility.

Are these charge air coolers made from aluminum or plastic tanks, and which is better?

We offer both aluminum tank and plastic tank options. Aluminum tanks are more durable and handle higher pressures better, making them ideal for heavy-duty applications and modified engines. Plastic tank models are lighter weight and more cost-effective for standard applications. Both meet or exceed OEM specifications. Aluminum tanks typically last longer in extreme conditions but may cost 20-30% more than plastic tank versions.

How difficult is the installation process, and what tools are required?

Installation typically takes 2-4 hours for experienced mechanics. You'll need basic hand tools, including socket sets, wrenches, and screwdrivers. A hose clamp plier set is highly recommended for the tight spaces. The most challenging part is usually accessing the lower mounting bolts and ensuring proper alignment. Some installations may require removing the grille or loosening the radiator for clearance. We recommend having new clamps and coolant on hand before starting.

What are the main differences between OEM replacement and aftermarket performance charge air coolers?

OEM replacement coolers match factory specifications exactly, ensuring direct fit and original performance levels. Performance aftermarket coolers feature increased core thickness (typically 2.5-3 inches vs 2 inches stock), additional cooling rows, and improved fin density for 15-25% better cooling efficiency. Performance models may require minor bracket modifications and are ideal for trucks with engine modifications or those operating in extreme conditions.

How can I tell if my charge air cooler is failing, and what warranty coverage is available?

Common failure signs include loss of boost pressure, increased exhaust temperatures, visible oil in the intake system, and decreased fuel economy. Physical inspection may reveal bent fins, leaking connections, or internal blockages. Most of our charge air coolers come with a 1-2 year warranty against manufacturing defects. Performance models typically include a 1-year warranty. Warranty doesn't cover damage from improper installation, road debris, or lack of maintenance.
