Full model list at the end of this description.

⚙️ Key Features

  • Rigid factory coolant routing
  • Correct flange and hose-end locations
  • Supersedes 3943401
  • Used across D9/D11/D13 industrial engines
  • Maintains coolant flow and component clearance
  • Engine type: 6-cylinder turbocharged industrial diesel

🔌 Function

Carries engine coolant between cooling-system components while maintaining the specified routing and flow area.

⚠️ Common Signs of Failure

  • Coolant seepage at a flange or hose end
  • Rust, pitting or pinhole leakage
  • Cracked mounting tab
  • Hose misalignment after pipe distortion
  • Coolant loss or overheating

🛠️ Service Notes

  • Clean both flanges or spigots and check the sealing lands for pitting and corrosion; renew every O-ring, seal or gasket at the joint rather than reusing one that has taken a set
  • Lubricate coolant-side O-rings with coolant or a rubber-safe lubricant — petroleum oil and grease swell and soften the rubber and end up in the coolant
  • Offer the pipe up and align both ends before pulling any fastener tight, so the joints are not held together by strain from a misaligned pipe or an over-stretched hose
  • Check the bore is clear of scale, sealant and debris before fitting, and inspect the pipe for internal corrosion or thinning if the old one was leaking
  • Refill with the coolant type and mix specified for your engine, bleed the system through, then check the joints again with the engine hot and up to pressure
