282-8217 Aftercoller Core — Cat 3512 785B

This aftercooler core is a heat exchanger that cools the compressed air from the turbocharger before it enters the engine cylinders, increasing air density for improved power and efficiency. Constructed from durable materials, it provides effective heat transfer and resistance to corrosion, outperforming a damaged or leaking core with bent fins or internal blockage. Operators might notice a decrease in engine power, increased exhaust gas temperatures, or excessive soot if this component 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

A failing aftercooler core may initially present as a gradual loss of engine power, especially under heavy load, and increased exhaust smoke. If the issue progresses, it can lead to significantly reduced performance, higher engine temperatures, and potential turbocharger damage due to increased backpressure. Continued operation risks inefficient combustion and reduced productivity.

Installation Tip

Ensure all connecting hoses and clamps are in good condition and properly sealed to prevent air leaks after installing the new aftercooler core. Do not use excessive sealant on the connections, as it can restrict airflow.

Service Note

Inspect the turbocharger and intake piping for any signs of oil leaks or damage when replacing the aftercooler core.
