Hoses, tubes and fittings carry coolant, oil, fuel and air between the components of an engine and its installation, and a failure in any of them can stop the engine as surely as a mechanical fault. This group covers coolant hoses and clamps, oil supply and drain lines, fuel lines and injector pipes, charge air pipes, and the unions and adaptors that join them. Machine-mounted Doosan engines subject hoses to constant vibration and articulation as well as heat, so failures commonly occur at clamps and bends rather than mid-length. High-pressure injector pipes on common rail engines are a special case: they should not be bent, reshaped or reused once removed, as work-hardening at the sealing ends leads to cracking under pressure.

It is not advised. The sealing ends work-harden in service and reshaping or refitting frequently results in cracking and leakage under high pressure.
At clamps and bends, where vibration and articulation concentrate stress, rather than in the middle of a run. Inspect these points first.
At every service, checking for hardening, softening, cracking and swelling. Hoses close to hot surfaces degrade fastest.
