216-5147 Aftercooler — Cat C12

This aftercooler is designed to reduce the temperature of the air charge entering the engine cylinders after it has been compressed by the turbocharger, increasing power and efficiency. It is constructed from durable materials to withstand engine operating conditions, offering better thermal management than a damaged unit. Operators might notice a loss of engine power, increased exhaust gas temperatures, or black smoke if this part is not functioning correctly.

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 first indication of a failing aftercooler is often a significant reduction in engine power and responsiveness. If left unaddressed, this can lead to increased exhaust temperatures and excessive black smoke. Continued operation with a faulty aftercooler can result in engine overheating and potential turbocharger damage.

Installation Tip

Ensure all air intake and outlet connections are thoroughly cleaned and free of any obstructions before installing the new aftercooler. Always use new clamps and gaskets for a secure seal.

Service Note

Inspect the turbocharger and intake manifold for oil or soot buildup when replacing the aftercooler.
