Frequently Asked Questions About Kenworth T660 Charge Air Coolers

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

Our Kenworth T660 charge air coolers are designed to fit 2008-2016 model years. They're compatible with most common engine configurations including Cummins ISX, Caterpillar C15/C13, and Paccar MX engines. However, specific mounting brackets and inlet/outlet sizes can vary by engine type. We recommend checking your current cooler's part number or contacting us with your VIN to ensure proper fitment.

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. The most challenging aspects are accessing the mounting bolts behind the grille and properly aligning the inlet/outlet connections. Many customers report that removing the front bumper provides better access. Always drain the cooling system first and have new coolant ready. Professional installation is recommended if you're not comfortable working with cooling systems.

What's the difference between OEM and aftermarket charge air coolers in terms of quality and performance?

Aftermarket charge air coolers often match or exceed OEM specifications at a lower price point. Our coolers feature aluminum cores with reinforced tanks and use the same fin density and tube design as original equipment. The main differences are typically in warranty coverage and minor design improvements. Many aftermarket options include thicker mounting brackets and improved welding at stress points based on common OEM failure patterns.

How can I tell if my charge air cooler needs replacement?

Common signs include loss of boost pressure, increased exhaust temperatures, visible coolant leaks around the cooler, oil residue in the intake system, and decreased fuel economy. A pressure test is the most reliable diagnostic method - coolers should hold 30 PSI for at least 15 seconds without dropping. Also check for bent fins blocking airflow, as even 25% fin damage can significantly reduce cooling efficiency.

What maintenance is required to maximize charge air cooler lifespan?

Clean the external fins every 6 months or 50,000 miles using compressed air blown from the engine side outward. Avoid high-pressure washing which can bend fins. Check all clamps and connections monthly for looseness or wear. Replace coolant according to manufacturer specifications, as degraded coolant can cause internal corrosion. Consider adding a pre-filter or bug screen to protect fins from debris, especially if you frequently drive in dusty conditions or areas with heavy insect populations.
