⚙️ Key Features

• Protects engine wiring from abrasion, heat and vibration

• Maintains separation from hot and moving engine components
• Direct replacement for a cracked, crushed or missing conduit
• Engine type: Mechanically or electronically controlled Volvo Penta diesel

🔌 Function

Routes and protects the engine harness so conductors cannot chafe, overheat or contact moving engine components.

⚠️ Common Signs of Failure

• Harness insulation chafing or exposed conductors
• Intermittent electrical faults caused by vibration
• Conduit cracking, crushing or heat deformation
• Harness contacting hot exhaust or moving belt components
• Water, oil or dirt entering the unprotected harness section

🛠️ Service Notes

• Renew the O-rings, seals, gaskets and clamps that seal the pipe rather than reusing them; most leaks after a pipe change come from a reused seal
• Offer the pipe up and get both ends aligned before tightening anything — pulling a rigid pipe into place strains the connections and cracks flanges and fittings
• Check the bore for scale, corrosion and debris and clean the mating faces on both components before assembly
• Refit every support bracket, clip and piece of insulation; an unsupported pipe fatigues at its joints from engine vibration
• Refill and vent the system, then leak check the joints and check them again after the first run up to working temperature
