260-0354 Air Aftercooler Core — Cat C11 C13

This air aftercooler core is a heat exchanger essential for cooling the compressed air exiting the turbocharger before it enters the engine cylinders. It is built to OEM specifications, ensuring efficient heat transfer and optimal engine performance, unlike a clogged or leaking core. Operators may observe a loss of engine power, increased exhaust gas temperatures, or visible coolant leaks if this component fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing aftercooler core is often a noticeable reduction in engine power, especially under load. If ignored, this can progress to higher exhaust temperatures and increased fuel consumption due to inefficient combustion. Continued operation with a compromised aftercooler risks overheating the engine and potentially damaging internal components.

Installation Tip

Ensure all mating surfaces for gaskets are perfectly clean and smooth before installation to guarantee a proper seal. Do not overtighten the mounting bolts, as this can distort the core and lead to leaks.

Service Note

Inspect the turbocharger, intake manifold, and all associated hoses and clamps for leaks or damage when replacing the aftercooler core.
