305-7597 Intercooler Air Hose — Cat 311D 312D

This intercooler air hose is designed to efficiently transfer compressed air from the turbocharger to the engine's intake manifold, ensuring optimal combustion. Constructed from durable, heat-resistant materials that meet OEM specifications, it offers superior longevity over cracked or collapsed hoses that restrict airflow. Operators may experience a loss of engine power, increased exhaust smoke, or a noticeable hissing sound from the engine bay when this hose 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

The first sign of a failing intercooler hose is often a reduction in engine power or a noticeable loss of boost pressure. If ignored, the hose can develop significant cracks or tears, leading to a substantial air leak, increased fuel consumption, and excessive black smoke from the exhaust. A complete hose rupture can cause a rapid loss of power and potentially allow debris into the intake system.

Installation Tip

Clean the mating surfaces on the turbocharger outlet and intake manifold thoroughly before installing the new hose to ensure a proper seal. Avoid using excessive force or sharp tools when positioning the hose, as this can cause damage to the rubber.

Service Note

Inspect the turbocharger outlet and intake manifold for any carbon buildup or damage, and check the condition of the hose clamps.
