265-9106 Aftercooler — Cat 797

This is an aftercooler, also known as an intercooler, which cools the compressed air from the turbocharger before it enters the engine cylinders. Manufactured to meet stringent OEM quality, it ensures optimal air density for improved combustion and performance, unlike a clogged or leaking aftercooler. Operators may notice a significant loss of engine power, increased exhaust gas temperatures, or overheating when 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

A primary indicator of a failing aftercooler is a noticeable reduction in engine power and responsiveness. If the unit is leaking or clogged, exhaust gas temperatures may rise, and the engine may run hotter than normal. Continued operation risks reduced engine efficiency and potential damage from excessive heat.

Installation Tip

Ensure all mounting surfaces are clean and free of debris before installing the new aftercooler to guarantee a proper seal. Avoid overtightening the mounting bolts, which can warp the mounting flanges.

Service Note

Inspect the turbocharger, intake piping, and exhaust system for any related issues when replacing the aftercooler.
