205-6687 Air Hose — Cat 320C 320D

This is an air intake hose designed to connect the air intake system components, ensuring clean air reaches the engine. It is manufactured to meet stringent OEM quality standards, providing superior durability and resistance to heat and ozone compared to worn or cracked hoses. A failing hose may cause a noticeable loss of engine power, rough idling, or a check engine light due to unmetered air entering the system.

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 air hose is often a decrease in engine performance or a rough idle. If left unaddressed, the hose can split further, leading to increased air leaks and potential engine damage. Continued operation with a compromised air intake can result in reduced fuel efficiency and increased emissions.

Installation Tip

Ensure the connection surfaces on both the turbocharger and air filter housing are clean and free of debris before installation. Do not overtighten the clamps, as this can damage the hose or the connection points.

Service Note

Inspect the air filter and air filter housing for any signs of damage or blockage when replacing the air hose.
