21259899 Charge Air Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine reinforced charge-air hose used between rigid turbocharger, charge-air cooler or inlet-manifold pipes. It is moulded to the original diameter and length and is designed to contain boost pressure, oil mist and elevated intake-air temperature.

⚙️ Key Features

• Boost-rated reinforced hose construction
• Factory bore, length and end geometry
• Resistant to heat, oil mist and engine vibration
• Maintains an airtight turbocharger-to-inlet connection
• Application controlled by the exact charge-air pipe arrangement

🔌 Function

The hose carries compressed air between the turbocharger, charge-air cooler and inlet manifold while absorbing engine movement.

⚠️ Common Signs of Failure

• Oil mist around a joint
• Whistling or hissing under load
• Loss of boost and engine power
• Hose swelling, splitting or delamination
• Hose collapsing or blowing off a connection

🛠️ Service Notes

• Check the hose is the one for the position and that its bends and any moulded ports match; charge air hoses are shaped for their location and a substitute that is only close will collapse or chafe through
• Clean the spigots and check them for corrosion, pitting or a lifted bead before fitting — a rough spigot will not seal against a new hose
• Push the hose fully onto each spigot so the clamp lands behind the bead, and fit new clamps where the originals are corroded or have been over-tightened and dug in
• Tighten the clamps evenly to the figure given in the workshop manual for your engine where one is specified, and re-check them after the first run up and again after the first period of use
• Look inside the hose while it is off: oil or soot in the bore points to something upstream that wants investigating before the new hose goes on
