1235205 Aftercooler Gasket — Cat 3406e c-15

This aftercooler gasket is a critical seal within the engine's cooling and air intake system, preventing leaks between the aftercooler and the engine block. Manufactured to precise tolerances, it ensures optimal sealing performance, unlike a degraded gasket that may allow coolant or boost pressure to escape. Operators might observe a loss of engine power, white smoke from the exhaust, or coolant in the oil when this gasket fails.

Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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 gasket may initially present as a slight reduction in engine power or an increase in exhaust temperature. If ignored, coolant can contaminate the intake air or oil, leading to lubrication issues and potential internal engine damage. The worst consequence is severe engine damage due to overheating or lubrication failure.

Installation Tip

Ensure both sealing surfaces on the engine block and aftercooler are perfectly clean and free of any debris or old gasket material. Do not reuse old bolts; use new ones if specified by the manufacturer.

Service Note

Inspect the aftercooler core for leaks or damage, and clean the charge air cooler hoses and connections when replacing the aftercooler gasket.
