Product Overview

The 2048378 is a genuine Paccar EGR cooler coolant pipe designed for Kenworth T680, T880, W900 and Peterbilt 579, 389 trucks. This pipe operates within the Exhaust Gas Recirculation cooling system and carries engine coolant to and from the EGR cooler. 

Product Features

The 2048378 EGR cooler coolant pipe is manufactured to Paccar factory specifications for routing engine coolant through the EGR cooling circuit.

  • Delivers engine coolant to the EGR cooler so heat can be transferred away from recirculated exhaust gases.
  • Returns coolant from the EGR cooler through the engine cooling circuit.
  • Supports the cooling process required before recirculated exhaust gases enter the engine intake.
  • Carries coolant through the portion of the EGR system exposed to high exhaust temperatures.
  • Helps the EGR cooler reduce the temperature of exhaust gases circulated back into the engine.
  • Maintains the coolant path used by the EGR system to support nitrogen oxide emission control.
