Multiquip EE49269 CAC Line Low Temp Cummins QSB5-G3

The Multiquip EE49269 is a genuine OEM CAC Line Low Temp Cummins QSB5-G3 designed for QSB5-G3 series equipment. As a direct Multiquip OEM component, EE49269 is manufactured to the exact specifications required for proper charge air cooling system function on QSB5-G3 powered units. This part ships as a direct replacement, ensuring a correct, hassle-free installation with no modifications needed to your existing setup. DHS Equipment stocks genuine Multiquip OEM parts so you can get your equipment back up and running with confidence.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications for the low-temperature charge air cooling circuit, ensuring the line handles the thermal cycling and pressure demands of the QSB5-G3 engine.
• Direct-Fit Replacement — Engineered to connect directly to the existing charge air cooler fittings and routing on QSB5-G3 powered equipment, requiring no adapters or rerouting.
• QSB5-G3 Fitment Confirmed — Specifically validated for Cummins QSB5-G3 engine applications within the Multiquip equipment lineup.
• Charge Air Cooling Integrity — A correctly functioning low-temp CAC line maintains proper intercooler efficiency; a cracked or deteriorated line allows hot air bypass, reducing engine output and risking overheating under load.
• Low-Temperature Circuit Rated — Built for the low-temp side of a two-stage charge air cooling system, where precise material compatibility with coolant and operating temperatures is critical to long service life.

The CAC (Charge Air Cooler) line on the low-temperature circuit carries coolant between the charge air cooler and the engine's low-temperature cooling loop, helping reduce the temperature of compressed intake air before it enters the combustion chamber. Cooler, denser intake air improves combustion efficiency and protects the engine from heat-related stress. When this line cracks, collapses, or develops a leak, coolant loss and reduced intercooler performance follow quickly, which can lead to elevated intake temperatures, power loss, and potential engine damage if left unaddressed.
