Peterbilt 367 Charge Air Coolers

Frequently Asked Questions About Peterbilt 367 Charge Air Coolers

What does a charge air cooler do on my Peterbilt 367?

The charge air cooler, also known as an intercooler, cools compressed air from the turbocharger before it enters the engine. Cooler, denser air improves combustion efficiency, helps the engine run at proper operating temperatures, and supports better fuel economy and horsepower output.

How do I know if my charge air cooler needs to be replaced?

Common signs of a failing charge air cooler include visible cracks or leaks in the end tanks or core, oil residue around fittings, a noticeable drop in power or fuel economy, boost leak codes, or excessive black smoke from the exhaust. If you notice any of these symptoms, it is a good idea to inspect the unit closely before it causes further engine strain.

Will a replacement charge air cooler fit my specific Peterbilt 367 model year?

Charge air coolers can vary by cab configuration, engine option, and production year, so it is important to check the fitment details listed on each product page or confirm your truck's VIN and engine specs with our team before ordering. Choosing the correct fit helps ensure proper mounting and airflow performance.

Are these charge air coolers OEM or aftermarket, and what materials are they made from?

Our selection includes both OEM and quality aftermarket charge air coolers. Most units feature aluminum cores for efficient heat transfer, paired with either aluminum or plastic end tanks depending on the manufacturer and model. Product listings specify the construction details so you can compare options based on durability and budget.

Can I install a charge air cooler myself, or should I have a professional do it?

Replacing a charge air cooler typically involves removing front-end components, disconnecting boost tubes and hoses, and properly securing the new unit to avoid air leaks. While experienced DIY mechanics can handle this job with the right tools, many owners prefer having a qualified technician complete the installation to ensure a proper seal and avoid boost leaks that can affect engine performance.
