The Multiquip EE48714 Upper CAC Line Cummins QSM11 is a genuine OEM charge air cooler line designed for QSM11-equipped Multiquip equipment. This is a direct OEM replacement sourced through Multiquip's authorized parts program, ensuring the correct routing, fitment, and material specification for QSM11 applications. If your machine is showing signs of heat-related power loss, intake air leaks, or visible damage to the charge air plumbing, the part is the correct OEM replacement to restore proper system integrity. DHS Equipment stocks this part to get your equipment back in service with confidence.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact specifications for the QSM11 charge air system, ensuring correct pressure rating, hose diameter, and routing geometry for this application.
- Direct Upper CAC Line Replacement — Replaces the upper charge air cooler line with a drop-in fit; connects between the turbocharger outlet and the charge air cooler inlet without modification to surrounding plumbing or mounting hardware.
- QSM11 Fitment Confirmed — Engineered specifically for Multiquip equipment powered by the Cummins QSM11 engine; reference model code QSM11 when verifying compatibility.
- Maintains Charge Air Pressure Integrity — A sound upper CAC line delivers fully cooled, pressurized intake air to the engine, supporting rated power output and fuel efficiency; a cracked or failed line causes charge air leakage, turbo surging, and engine derating.
- Fuel System and Intake Safety — A compromised charge air line can allow debris ingestion or unmetered air into the intake tract, leading to uncontrolled engine behavior; an OEM replacement restores sealed system integrity.
The upper charge air cooler (CAC) line is a pressurized hose or hard-line segment that carries hot, compressed air from the turbocharger outlet to the charge air cooler (intercooler). The cooler drops the intake air temperature before it enters the engine, increasing air density and allowing the engine to produce its rated power output efficiently. When this line cracks, collapses, or loses a clamp connection, the engine receives less dense, hotter air than intended — resulting in visible black smoke, reduced power, elevated exhaust temperatures, and potential engine protection shutdowns. Replacing a failed upper CAC line promptly prevents cascading stress on the turbocharger and engine internals.
