Detailed Product Overview

This Dorman EGR cooler hose, part number 598-5944, is engineered as a direct replacement for the original hose used in the vehicle’s EGR cooling circuit. It is designed for applications that require a cast iron EGR tube with straight-to-straight connections and a 1.189 in. inside diameter at each end. This part cross-references GM OE numbers 20818008 and 20966370 for the same application.

Common Repair Uses

  • Cracked or heat-damaged EGR cooler hose
  • Exhaust gas leakage at the EGR tube connection
  • Restricted EGR flow caused by a damaged hose assembly
  • Failed emissions inspection related to EGR system faults
  • Replacement for worn OE EGR cooler tube hardware on select GM vehicles

Installation Notes and Tips

Verify the hose length, end style, and inside diameter before installation. Because no gasket or seal is included, reuse or replace sealing components as required by the vehicle service procedure. Confirm the routing and connection points on the EGR cooler and related emission control components before tightening the assembly.
