113-4655-1134655 Aftercooler 113 4655 — Cat 3516 3508

This is an Aftercooler, a critical component of the engine's air intake system that cools compressed air before it enters the cylinders. It is built to meet rigorous OEM standards, offering superior heat dissipation and durability over a worn or damaged unit. Operators might observe a loss of engine power, increased exhaust smoke, or higher operating temperatures when the aftercooler is malfunctioning.

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 failing aftercooler may first present as a subtle decrease in engine power or increased fuel consumption. If ignored, internal leaks can lead to coolant contamination or oil in the intake, progressively worsening performance. Continued operation risks severe engine damage from overheating and improper combustion.

Installation Tip

Thoroughly clean the mounting surfaces and ensure all O-rings and seals are correctly seated before assembly. Avoid using excessive force when connecting hoses or pipes, as this can damage the aftercooler core or fittings.

Service Note

Inspect the turbocharger and intake manifold gaskets for leaks when servicing the aftercooler.
