21153527 Charge Air Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta earlier-generation charge-air pipe now serviced by replacement part 21507760. The rigid pipe carries compressed air between the turbocharger, charge-air cooler and intake connection while maintaining the correct sensor, hose and clamp geometry for its production version.

⚙️ Key Features

• Genuine Volvo Penta charge-air pipe reference
• Rigid formed pipe for the pressurised charge-air system
• Replacement pipe revision can require matching hoses, clamps or brackets
• Engine model and serial break must be checked before installation
• Engine type: Turbocharged Volvo Penta marine or industrial diesel

🔌 Function

Transfers compressed charge air between the turbocharger, cooler and intake manifold with minimal leakage and pressure loss.

⚠️ Common Signs of Failure

• Boost leakage, hissing or oil-mist tracking at a joint
• Reduced power, slow turbo response or increased exhaust smoke
• Split rubber, cracked pipework or loose clamps
• High charge-air temperature or related sensor faults
• Misalignment or vibration damage at supports and connections

🛠️ Service Notes

• Clean both sealing faces before assembly and check the rubber sleeves, seals and clamps; hardened, swollen or split sleeve rubber will not hold boost on a new pipe
• Seat the pipe fully onto its spigots and set each clamp behind the bead before tightening, so pressure cannot push the joint apart
• Align and support the pipe on its brackets so it is not pulled into tension — a pipe held under strain chafes, cracks and works its clamps loose
• Check the bore for oil sludge and soot before fitting and clean it out; carried-over oil softens sleeve rubber and blackens a new pipe from the inside
• Tighten clamps and any flange fasteners to the figures in the workshop manual for your engine, then re-check them after the first run under load
