Kenworth T800 Charge Air Coolers

Frequently Asked Questions About Kenworth T800 Charge Air Coolers

What does a charge air cooler do on my Kenworth T800?

A charge air cooler, also known as an intercooler, cools the compressed air coming from the turbocharger before it enters the engine. Cooler, denser air improves combustion efficiency, helps the engine produce more power, and reduces strain on internal components. If your T800 is losing power, running hotter than normal, or showing increased fuel consumption, a failing charge air cooler could be the cause.

Will a charge air cooler for the T800 fit my specific truck?

Fitment can vary based on engine model, model year, and cab configuration, so it is important to check the listed specifications and compatible engine applications before ordering. If you are unsure whether a particular charge air cooler matches your truck, check your VIN or existing part number against the compatibility details on the product page, or contact our parts team for confirmation before purchasing.

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 leaks around the core, reduced engine power, black smoke from the exhaust, or a noticeable drop in fuel economy. A pressure test performed by a qualified technician is the most reliable way to confirm a leak or internal failure before replacing the unit.

Are these charge air coolers new, remanufactured, or used?

Product condition varies by listing, so be sure to check each product description for details on whether the charge air cooler is new, reconditioned, or a take-off part. Each option comes with different pricing and warranty coverage, so review the listing carefully to choose the best fit for your budget and reliability needs.

What should I check before installing a replacement charge air cooler?

Before installation, inspect all connecting hoses, clamps, and mounting brackets for wear or damage, since these components can affect the seal and performance of the new cooler. It is also a good idea to have the system pressure tested after installation to confirm there are no leaks and that the repair fully resolves the original issue.
