The charge air cooler (also called a CAC or intercooler) cools compressed air coming from the turbocharger before it enters the engine. Cooler, denser air means better combustion, more power, and lower fuel consumption. When a CAC develops cracks or leaks — often from vibration or road debris — you'll notice black smoke, power loss, and rising fuel bills. At True Truck Parts, we carry OEM-spec charge air coolers for all major semi truck makes including Freightliner, Kenworth, Peterbilt, Volvo, Mack, and International.
The Freightliner Cascadia is the most common semi truck on Canadian roads, and its DD13 and DD15 engines are hard on CACs — vibration and flex in the chassis causes hairline cracks in the core over time. We carry direct-fit Cascadia charge air coolers that bolt in without modification, priced from $350–$700 CAD. The Kenworth T680 with the PACCAR MX-13 engine is similarly demanding — we stock CACs for the full T680 production run.
For Peterbilt 386 and 389 trucks running the Cummins ISX or PACCAR MX, we carry aluminum bar-and-plate CACs built to OEM core depth and fin density. Volvo VNL owners running the D13 engine will find both OEM-spec and heavy-duty upgraded options in our catalog. Mack Anthem and Pinnacle CACs for the MP8 engine are also in stock.
All charge air coolers are pressure-tested before shipping. We serve fleets and owner-operators across Mississauga, Brampton, Vaughan, Milton, Oakville, Burlington, Hamilton, Pickering, Ajax, Oshawa, and the greater GTA. Same-day quoting available — call (437) 868-4875.

Browse parts →A charge air cooler cools the compressed air coming from the turbocharger before it enters the engine cylinders. Cooler air is denser, which means more oxygen per combustion cycle — resulting in better power output, improved fuel efficiency, and lower exhaust temperatures. A leaking CAC reduces boost pressure and causes the engine to run rich, producing black smoke and increased fuel consumption.
Symptoms include excessive black smoke from the exhaust, noticeable loss of power especially under load, increased fuel consumption, a hissing noise from the intake system, boost pressure codes on the ECM, or oil residue inside the intake piping from a cracked CAC allowing oil-laden air to bypass the system.
Our CAC inventory covers Freightliner (Cascadia, Columbia, Century), Kenworth (T680, T880, W900), Peterbilt (386, 387, 389), Volvo (VNL series), Mack (Anthem, Pinnacle, Granite, CXU), International (LT, RH, ProStar), and Western Star (4900, 5700).
Disconnect the CAC from the intake piping, plug both ends, and pressurize to 20–30 PSI using shop air. Submerge in water or spray with soapy water and look for bubbles. Any bubbling indicates a crack or pinhole leak. Even small leaks cause significant boost pressure loss on a turbocharged diesel.
Replacement charge air coolers for semi trucks typically cost between $300 and $900 CAD depending on the make and model. A Freightliner Cascadia CAC runs approximately $350–$600, while Kenworth T680 and Peterbilt 389 units are in the $400–$750 range. Dealer pricing is usually 40–60% higher. At True Truck Parts we offer OEM-spec fitment at aftermarket pricing with Canada-wide shipping.
Technically yes, but it is not advisable. A leaking CAC reduces boost pressure, causing the engine to work harder, consume more fuel, and produce more exhaust smoke. Over time, running with low boost can accelerate wear on turbocharger seals and EGR components. Most fleets replace a failed CAC within 1–2 days to avoid compounding repair costs.
A quality charge air cooler typically lasts 500,000 to 800,000 km under normal operating conditions. Trucks operating in cold climates — like Canadian winters — see faster degradation due to thermal cycling. Cascadia trucks on interstate runs often need CAC replacement between 600,000 and 900,000 km. Regular visual inspections at oil change intervals are recommended.
Yes. We ship to all provinces including Ontario, Alberta, British Columbia, Quebec, Manitoba, and Saskatchewan. Most orders ship within 1–2 business days. We serve customers across the GTA — Mississauga, Brampton, Vaughan, Hamilton, Oakville — and coast to coast.
