Multiquip EE51147 Aftercooler Line Lower KTA50 Rocor Rad

The Multiquip EE51147 is a genuine OEM Aftercooler Line Lower KTA50 Rocor Rad designed for KTA50 series equipment. Sourced directly from Multiquip, this part meets the original engineering specifications for the KTA50 cooling system, ensuring a direct, trouble-free installation. DHS Equipment stocks this component so you can get your machine back up and running without delay. Confirm your model code against KTA50 before ordering to ensure correct fitment.

Key Features

• Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the KTA50 aftercooler circuit, so cooling performance is maintained at the level the machine was designed to deliver.
• Direct-Fit Replacement — Engineered to connect at the same routing points and with the same end fittings as the original lower aftercooler line, eliminating guesswork during installation.
• KTA50 Fitment Confirmed — Validated for KTA50 series equipment; cross-reference your model code before ordering to ensure this is the correct lower line position for your configuration.
• Cooling System Integrity — A compromised or collapsed aftercooler line restricts charge-air flow through the aftercooler core, leading to elevated intake temperatures and reduced engine output; replacing it restores proper thermal management.
• OEM Part Number EE51147 — Use part number EE51147 when ordering through DHS Equipment or submitting a service work order to ensure you receive the correct assembly for the lower line position.

The lower aftercooler line routes compressed, heated charge air from the turbocharger through the aftercooler (also called an intercooler or charge-air cooler) where it is cooled before entering the engine's intake manifold. Cooling the charge air increases its density, allowing the engine to burn fuel more efficiently and produce rated power output. When this line cracks, collapses, or develops a leak, charge-air pressure drops and intake temperatures rise, which can cause the engine to run hot, lose power, or trigger protective shutdowns. Replacing a worn lower aftercooler line promptly protects both engine performance and long-term reliability.
