Peterbilt 587 Charge Air Coolers

Frequently Asked Questions About Peterbilt 587 Charge Air Coolers

What does a charge air cooler do on my Peterbilt 587?

The charge air cooler, also called an intercooler, cools compressed air from the turbocharger before it enters the engine. Cooler, denser air improves combustion efficiency, helps the engine produce power more effectively, and reduces strain on internal components. A properly functioning charge air cooler also supports emissions system performance.

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

Common signs of a failing charge air cooler include visible cracks, oil residue or coolant buildup around the fins, reduced engine power, increased turbo lag, black smoke from the exhaust, or a noticeable drop in fuel economy. If you notice any of these symptoms, it is a good idea to have the unit inspected for leaks or physical damage before they lead to bigger engine issues.

Will this charge air cooler fit my specific Peterbilt 587 model year?

Charge air coolers can vary based on engine configuration, cab style, and production year, so fitment is not always universal across every 587. Before purchasing, check the listed specifications and compare them to your truck's existing unit or VIN details. If you are unsure, our team can help confirm compatibility so you order the correct part the first time.

Are these charge air coolers new, or are remanufactured or used options available?

We offer a range of options depending on availability, including new aftermarket units. Product listings specify the condition of each part, so you can choose based on your budget and how long you plan to keep the truck in service. New units typically come with a warranty, which is worth factoring into your decision.

What should I check during installation to avoid future problems?

When installing a charge air cooler, inspect all mounting brackets, hoses, and clamps for wear before reattaching them, and replace any that show cracking or fatigue. Make sure connections are properly torqued and sealed to prevent boost leaks, and run the engine to check for leaks or unusual noises before putting the truck back into regular service. If you are not comfortable performing the installation yourself, a qualified diesel technician can ensure it is fitted and sealed correctly.
